Connect a Category 3, 4, or 5 unshielded twisted-pair cable to the Ethernet  
connector. 100BASE-TX and 1000BASE-T Fast Ethernet standards require  
Category 5 or higher cabling. The WAVE appliance has one Ethernet connector  
(see Figure 1-3).  
The Ethernet controller is integrated on the system board. It provides an interface  
for connecting to a 10-Mbps, 100-Mbps, or 1-Gbps network and provides  
full-duplex (FDX) capability, which enables simultaneous transmission and  
reception of data on the network. If the Ethernet port in the server supports auto  
negotiation, the controllers detect the data-transfer rate (10BASE-T,  
100BASE-TX, or 1000BASE-T) and duplex mode (full duplex or half duplex) of  
the network and automatically operate at that rate and mode. You do not have to  
set any jumpers or configure the controller.

Chapter 2 Preparing to Install the Wide Area Virtualization Engine  
Safety Guidelines  
The air baffle assembly is always installed in the appliance except when you  
are installing or removing the components that are located under the air baffle  
cover.  
When the air baffle assembly is installed in the appliance, the air baffle cover  
is always closed.  
Microprocessor socket 2 always contains either a microprocessor baffle or  
a microprocessor.  
Protecting Against Electrostatic Discharge  
Static electricity can harm delicate components inside the appliance. To prevent  
static damage, discharge static electricity from your body before you touch any of  
your system’s electronic components. You can do so by touching an unpainted  
metal surface on the chassis.  
You can also take the following steps to prevent damage from electrostatic  
discharge (ESD):  
When unpacking a static-sensitive component from its shipping carton, do not  
remove the component from the antistatic packing material until you are  
ready to install the component in your system. Just before unwrapping the  
antistatic packaging, be sure to discharge static electricity from your body.  
When transporting a sensitive component, first place it in an antistatic  
container or packaging.  
Handle all sensitive components in a static-safe area. If possible, use  
antistatic floor pads and workbench pads.  
Handle the device carefully, holding it by its edges or its frame.  
Do not touch solder joints, pins, or exposed printed circuitry.  
Do not leave the device where others can handle and possibly damage the  
device.  
Take additional care when handling devices during cold weather, because  
heating reduces indoor humidity and increases static electricity.

Installing the WAVE Appliance on a Tabletop  
Installing the WAVE Appliance on a Tabletop  
When you install a WAVE appliance on a workbench or tabletop, ensure that the  
surface is clean and in a safe location and that you have considered the following  
points:  
The WAVE appliance should be installed off the floor. (Dust that accumulates  
on the floor is drawn into the interior of the chassis by the cooling fans.  
Excessive dust inside the WAVE appliance can cause overtemperature  
conditions and component failures.)  
There must be approximately 19 inches (48.26 cm) of clearance at the front  
and rear of the WAVE appliance for accessing network cables or equipment.  
The front should be completely clear. Leave 0.4 inches (10-mm) of clearance  
on the sides and top of the appliance and at least 2.0 inches (50 mm) of  
clearance in the rear. The rear vents should be completely clear.  
To install the WAVE appliance on a workbench or tabletop, follow these steps:  
Step 1  
Remove any debris and dust from the tabletop or workbench, as well as from the  
surrounding area. Also make sure that your path between the WAVE appliance and  
its new location is unobstructed.  
Step 2  
Step 3  
Place the chassis on the tabletop or workbench.  
Ensure that no exhaust air from other equipment will be drawn into the chassis.  
Also make sure that there is adequate clearance at the front and rear of the chassis.  
Installing the WAVE Appliance on a Wall  
You can mount the WAVE appliance on a wall or underneath a desk or workbench  
using the optional mounting sleeve. See Figure 3-1 on page 3-3. Make sure that  
you consider the location requirements as described in the “Installing the WAVE  
Appliance on a Tabletop” section on page 3-2.

equipment rack. Make sure that you follow the guidelines described in the  
following topics:  
Rack-Mounting Considerations, page 3-5  
Rack Requirements, page 3-6  
Rack-Mounting Considerations  
Before installing your WAVE appliance in a rack, review the following guidelines:  
Ensure that the room air temperature is below 95 °F (35 °C).  
Do not block any air vents; usually 6 inches (15 cm) of space provides proper  
airflow.  
Plan the device installation starting from the bottom of the rack.  
Install the heaviest device in the bottom of the rack.  
Do not extend more than one device out of the rack at the same time.  
Remove the rack doors and side panels to provide easier access during  
installation.  
Connect the WAVE appliance to a properly grounded outlet.  
Do not overload the power outlet when installing multiple devices in the rack.  
Caution  
Caution  
Use safe practices when lifting.  
Do not place any object weighing more than 110 lb (50 kg) on top of  
rack-mounted devices.  
Caution  
Install the appliance only in a rack cabinet with perforated doors.

Connecting Cables  
Rack Requirements  
Install your WAVE appliance in a rack that meets the following requirements:  
Minimum depth of 2.76 inches (70 mm) between the front mounting flange  
and inside of the front door.  
Minimum depth of 6.18 inches (157 mm) between the rear mounting flange  
and inside of the rear door.  
Minimum depth of 28.27 inches (718 mm) and maximum depth of 30 inches  
(762 mm) between the front and rear mounting flanges to support the use of  
the cable-management arm.  
Racks are marked in vertical increments of 1.75 inches (4.44 cm). Each increment  
is referred to as a rack unit (RU). A 1-RU device is 1.75 inches (4.44 cm) tall.  
Connecting Cables  
To connect cables to your WAVE appliance, follow these steps:  
Step 1  
Step 2  
Power down the appliance before connecting cables to or disconnecting any  
cables from the appliance.  
See the documentation that comes with your optional equipment for additional  
cabling instructions. It might be easier for you to route the cables before you  
install specific optional equipment.  
Step 3  
See the cable identifiers that are printed on the cables that come with the WAVE  
appliance and options. Use these identifiers to connect the cables to the correct  
connectors.  
Figure 1-2 shows the locations of the input and output connectors on your  
appliance.  
Connecting Power and Booting the System  
To connect power to your system, follow these steps:

Checking the LEDs  
Step 1  
Step 2  
Review the information in the “Safety Guidelines” section on page 2-4.  
Plug a power cord into the power cord receptacle on the back of the WAVE  
appliance.  
Step 3  
Step 4  
Step 5  
Connect the other end of the power cord to a power source at your installation site.  
Power up all externally connected devices.  
Press the power control button on the front of the WAVE appliance.  
The system should begin booting. Once the operating system boots, you are ready  
to initialize the basic software configuration. (See the software configuration  
guide for details.)  
Note  
While the WAVE appliance is powering up, the green power-on LED on  
the front of the WAVE appliance is on.  
Checking the LEDs  
When the WAVE appliance is up and running, observe the front panel LEDs (see  
Figure 1-1 and Table 1-1) to verify that your system is operating properly.  
To troubleshoot using the LEDs, see Chapter 5, “Troubleshooting the System  
Hardware.”  
Removing or Replacing a WAVE Appliance  
To remove a WAVE appliance from your network, power it down, disconnect the  
power cords and network cables, and physically remove the chassis from the rack.  
The WAVE appliance is in constant communication with the router on your  
network. When the router notices that the WAVE appliance is no longer  
responding to it, the router stops sending requests to the WAVE appliance. This  
action is transparent to users. If other WAVE appliances are attached to the router,  
the router continues sending requests to the other WAVE appliances.

Chapter 3 Installing the Wide Area Virtualization Engine  
Removing or Replacing a WAVE Appliance  
When you remove a WAVE appliance, the pages that were cached on that device  
are no longer available to the router or other WAVE appliances. You might see an  
increase in outgoing web traffic that might have otherwise been fulfilled by the  
WAVE appliance that you are removing. However, after a time, the router and  
other WAVE appliances redistribute the load of web traffic.  
If you remove the last WAVE appliance from your network, you can also disable  
WAVE appliance support on the router. However, this action is not necessary  
because leaving WAVE appliance support enabled when there are no WAVE  
appliances attached has no effect on the router’s performance.  
To replace a WAVE appliance, remove it from the network, and then install a new  
WAVE appliance and configure it using the same configuration parameters (IP  
address and so forth) that you used for the removed WAVE appliance.

Inline Network Adapter Description  
The WAVE-274 and WAVE-474 appliances include one 2-port Gigabit Ethernet  
inline network adapter.  
The Cisco WAVE inline network adapter provides inline traffic interception  
capability for your appliance. When you configure the WAVE appliance for inline  
interception mode, you can set attributes to control which interfaces are to be used  
over which VLANs. By default, the adapter operates on all inline-capable  
interfaces and VLANs. You can configure the inline redirection feature using the  
WAAS CLI or the WAAS Central Manager GUI.

Chapter 4 WAVE Inline Network Adapter  
Inline Network Adapter Description  
Note  
Throughout this section, we refer to a WAVE appliance configured for inline  
interception mode as a WAVE inline appliance.  
The WAAS software defines two new interface types: A group interface that  
represents an inline pair grouping and a port interface that represents the  
individual port. These interfaces are referred to as inlineGroup and inlinePort.  
InlineGroup interfaces are numbered using the format slot/group. The slot number  
is the slot in which the adapter is inserted. The group number is either 0 or 1 (each  
adapter has 2 group pairs). The group number is displayed on the adapter label.  
InlinePort interfaces are numbered slot/group/lan or slot/group/wan. The last  
attribute is the LAN or WAN designator.  
The inline network adapter also includes an onboard programmable watchdog  
timer (WDT) controller that allows you to set the time to wait after a failure event,  
such as a power outage or a kernel crash, before the unit begins to operate in  
mechanical bypass mode. In mechanical bypass mode, the traffic is bridged  
between the LAN and WAN ports of each group. Mechanical bypass mode  
prevents the WAVE appliance from becoming a single point of failure and allows  
traffic to continue to flow between the router and the client while it passes through  
an unresponsive WAVE appliance without being processed.  
For more information about configuring the inline network adapter, see the Cisco  
Wide Area Application Services Configuration Guide.

Chapter 4 WAVE Inline Network Adapter  
Inline Network Adapter Cabling Requirements  
Inline Network Adapter Cabling Requirements  
The inline network adapter ships with two types of cables: crossover and  
straight-through. When you connect the WAVE inline network adapter, the cable  
that you use depends on the link speed (Gigabit Ethernet or Fast Ethernet) and the  
types of devices (DCE or DTE) being connected.  
Note  
You must retain the same link speed from one end of the connection to the other  
end. Inline adapter interfaces are able to autonegotiate link speeds. If you  
configure any of your connecting interfaces for Fast Ethernet (whether on a switch  
or a router), your WAVE inline adapter uses Fast Ethernet. If you configure any  
of your connecting interfaces for Gigabit Ethernet, your WAVE inline adapter  
uses Gigabit Ethernet. Speed and duplex settings are port specific so that two  
inline ports can negotiate different speeds independently.  
If you are connecting a WAVE inline appliance between two devices using Gigabit  
Ethernet, you can use either straight-through cables, crossover cables, or any  
combination of the two cable types, regardless of the type of device. However, for  
consistency, we recommend that you use straight-through cables for all Gigabit  
Ethernet connections.  
Table 4-2 shows the cable requirements for WAVE appliance and non-WAVE  
appliance connections when you are using Gigabit Ethernet end to end.

Some switches support automatic medium-dependent interface crossover  
(MDIX). You can configure MDIX by using the mdix auto global configuration  
switch command. If your switch supports MDIX, you do not need to follow these  
cabling rules because MDIX automatically adjusts transmit and receive pairs  
when an incorrect cable type (crossover or straight-through) is installed on a  
Caution  
If you are connecting to Fast Ethernet ports on both the LAN and the WAN sides  
of the WAVE inline appliance, you must consider the types of devices that are  
being connected, and you must use the correct cables. You must follow these  
cabling instructions for the inline network adapter to work properly. (See  
Table 4-3. For illustrations and examples, see the “Installation Scenarios and  
Cabling Examples for Fast Ethernet Connections” section on page 4-7.)  
To connect the inline network adapter using the correct cables for Fast Ethernet  
connections, follow these steps:  
Step 1  
Determine the type of cable that you would use for a direct connection between  
your two end devices (without a WAVE inline network appliance connected  
between them) by using the following standard cabling rules:  
When you are directly connecting two network devices that are similar, such  
as two switches, use a crossover cable.  
When you are directly connecting two network devices that are different, such  
as a switch and router, use a straight-through cable.

Chapter 4 WAVE Inline Network Adapter  
Inline Network Adapter Cabling Requirements  
Note  
Because the inline network adapter has an internal crossover connection  
that becomes active when the InlineGroup interface is placed in  
mechanical bypass mode, you must decide which cable you would use to  
connect the two network devices directly, and then you must install the  
other cable type (on one side, usually the WAN side of the inline  
appliance) instead.  
Table 4-3 shows the cable requirements for WAVE and non-WAVE connections  
when you are using Fast Ethernet end to end.

Connect Fast Ethernet ports on both the LAN and the WAN sides of the WAVE  
inline appliance by using the following cable types:  
On the LAN side of the connection, use a straight-through cable between the  
WAVE inline appliance and the network device.  
On the WAN side of the connection, use the cable that is different from the  
cable that you would use to connect the two network devices directly (as  
determined in Step 1).

Chapter 4 WAVE Inline Network Adapter  
Installation Scenarios and Cabling Examples for Fast Ethernet Connections  
For example, if you are connecting a router and a switch (two different  
devices) through the WAVE inline appliance, use a straight-through cable on  
the LAN side of the connection and use a crossover cable on the WAN side  
of the connection. (If you were connecting the two different devices directly,  
you would use a straight-through cable, so use the crossover cable instead.)  
If you are connecting two switches (or two similar devices), use  
straight-through cables on both the LAN and the WAN sides of the WAVE  
inline appliance.  
Figure 4-2 and Figure 4-3 show which cables to use for the WAVE LAN and  
WAN connections between Fast Ethernet ports.  
Installation Scenarios and Cabling Examples for Fast  
Ethernet Connections  
WAVE appliances can be installed physically between two network devices (such  
as the branch office router and branch office LAN switch) by connecting the  
WAVE inline network adapter ports to the network devices using the proper  
cables.  
If you are connecting a WAVE inline appliance between two devices using Gigabit  
Ethernet, you can use either straight-through cables, crossover cables, or any  
combination of the two cable types, regardless of the type of device. This section  
shows cabling examples for Fast Ethernet connections only, because Fast Ethernet  
has specific cabling requirements.  
Two WAVE appliances with inline network adapters can be installed back-to-back  
in a serial fashion between two network devices for failover purposes. In this  
serial cluster configuration, if one WAVE appliance fails or becomes overloaded,  
the other WAVE appliance can provide optimization. (See Figure 4-2.)  
Note  
When you connect two WAVE inline appliances to each other serially, always use  
a crossover cable between the two WAVE appliances. (See Figure 4-3.)

Chapter 5 Troubleshooting the System Hardware  
Identifying System Problems  
Note  
The WAAS software does not support the use of a keyboard or mouse  
(Personal System/2 [PS/2] or Universal Serial Bus [USB]) for Linux and WAAS  
software troubleshooting. However, the keyboard and mouse are supported by the  
BIOS for power-on self-test (POST) and the diagnostic programs that are located  
in the device ROM.  
When console redirection is enabled, all the tests available from a keyboard are  
accessible through the console connection as well. (Mouse support, however, is  
not available through the console connection.)  
You can run all the diagnostics and tests that are supported by the BIOS, with a  
few exceptions. Tests for ports (such as the systems-management Ethernet  
connector and the SAS connector) that are not supported by the WAAS software  
are invalid.  
Identifying System Problems  
To identify system problems, follow these steps:  
Step 1  
Step 2  
Check the front panel LED indicators. (See Table 5-10 on page 5-13.)  
Power down the device and all external devices.  
Check all cables and power cords. (See the “Checking Connections and Switches”  
section on page 5-3.)  
Step 5  
Step 6  
Power up the device.  
Record any POST error messages that are displayed on the screen. If an error is  
displayed, look up the first error in the “Power-On Self Test (POST)” section on  
page 5-12.  
Step 7

Chapter 5 Troubleshooting the System Hardware  
Checking Connections and Switches  
Checking Connections and Switches  
Improperly set switches and controls and loose or improperly connected cables  
are the most likely source of problems for the chassis or other external equipment.  
A quick check of all the switches, controls, and cable connections can easily  
solve these problems. (See Figure 1-1 for the location of front panel controls  
and indicators. See Figure 1-2 for the location of back panel connectors on  
the system.)  
To check all the connections and switches, follow these steps:  
Step 1  
Step 2  
Power down the system. Disconnect all the power cables from their electrical  
outlets.  
If the system is connected to a power strip (or power distribution unit), turn the  
power strip off and then on again.  
Is the power strip receiving power?  
Yes. Go to Step 5.  
No. Go to Step 3.  
Step 3  
Step 4  
Plug the power strip into another electrical outlet.  
Is the power strip receiving power?  
Yes. The original electrical outlet probably does not function. Use a different  
electrical outlet.  
No. Go to Step 4.  
Plug a system that you know works into the electrical outlet.  
Does the system receive power?  
Yes. The power strip is probably not functioning properly. Use another power  
strip.  
No. Go to Step 5.  
Step 5  
Step 6  
Reconnect the system to the electrical outlet or power strip.  
Make sure that all connections fit tightly together.  
Power up the system.  
Is the problem resolved?  
Yes. The connections were loose. You have fixed the problem.

Troubleshooting the Ethernet Controller  
No. Call your customer service representative. (See the “Obtaining  
Documentation, Obtaining Support, and Security Guidelines” section on  
page xix.)  
This section provides troubleshooting information for problems that might occur  
with the 10/100/1000-Mbps Ethernet controller.  
This section contains the following topics:  
Network Connection Problems, page 5-4  
Ethernet Controller Troubleshooting Chart, page 5-5  
Network Connection Problems  
If the Ethernet controller cannot connect to the network, check the following  
conditions:  
Make sure that the cable is installed correctly.  
The network cable must be securely attached at all connections. If the cable  
is attached but the problem remains, try a different cable.  
If you set the Ethernet controller to operate at either 100 Mbps or 1000 Mbps,  
you must use Category 5 or higher cabling.  
Determine whether the switch or device to which the WAVE appliance is  
connected supports autonegotiation. If it does not, try configuring the  
integrated Ethernet controller manually to match the speed and duplex mode  
of the switch.  
Check the Ethernet controller LEDs on the device back panel. (See  
Figure 1-2.)  
These LEDs indicate whether a problem exists with the connector, cable,  
or switch:

Troubleshooting the Ethernet Controller  
The Ethernet link status LED is on when the Ethernet controller receives  
a link pulse from the switch. If the LED is off, there might be a defective  
connector or cable or a problem with the switch.  
The Ethernet activity LED is on when the Ethernet controller sends or  
receives data over the Ethernet network. If the Ethernet activity LED is  
off, make sure that the switch and network are operating and that the  
correct device drivers are installed.  
Make sure that you are using the correct device drivers that are supplied with  
your device and that the device drivers on the client and the device are using  
the same protocol.  
Check for operating system-specific causes for the problem.

Maintaining the Wide Area  
Virtualization Engine  
Proper use of preventive maintenance procedures can keep the Wide Area  
Virtualization Engine (WAVE) in good operating condition and minimize the need  
for costly, time-consuming service procedures. This chapter contains  
maintenance procedures that you should perform regularly.  
This chapter covers the tasks required for maintaining a WAVE appliance or a  
WAVE farm:  
Maintaining Your Site Environment, page B-1  
Using Power Protection Devices, page B-7  
Maintaining Your Site Environment  
An exhaust fan in the power supply cools the power supply and system by drawing  
air in through various openings in the system and blowing it out the back.  
However, the fan also draws dust and other particles into the system, causing  
contaminant buildup, which results in an increase in the system’s internal  
temperature and interferes with the operation of various system components.  
To avoid these conditions, we recommend keeping your work environment clean  
to reduce the amount of dust and dirt around the system, thereby reducing the  
amount of contaminants drawn into the system by the power supply fan.  
This section discusses various environmental factors that can adversely affect  
system performance and longevity.

Temperature  
Temperature extremes can cause a variety of problems, including premature aging  
and failure of chips or mechanical failure of devices. Extreme temperature  
fluctuations can cause chips to become loose in their sockets and can cause  
expansion and contraction of disk drive platters, resulting in read or write data  
errors.  
To minimize the negative effects of the temperature on system performance,  
follow these guidelines:  
Ensure that the system is operated in an environment no colder than 50 °F  
(10 °C) or hotter than 95 °F (35 °C).  
Ensure that the system has adequate ventilation. Do not place it within a  
closed-in wall unit or on top of cloth, which can act as insulation. Do not  
place it where it will receive direct sunlight, particularly in the afternoon. Do  
not place it next to a heat source of any kind, including heating vents during  
winter.  
Adequate ventilation is particularly important at high altitudes. System  
performance may not be optimum when the system is operating at high  
temperatures as well as high altitudes.  
Make sure that all slots and openings on the system remain unobstructed,  
especially the fan vent on the back of the system.

Appendix B Maintaining the Wide Area Virtualization Engine  
Maintaining Your Site Environment  
Clean the system at regular intervals to avoid any buildup of dust and debris,  
which can cause a system to overheat.  
If the system has been exposed to abnormally cold temperatures, allow a  
2-hour warm-up period to bring it up to a normal operating temperature  
before turning it on. Failure to do so may cause damage to internal  
components, particularly the hard disk drive.  
If intermittent system failures are noticed, try reseating any socketed chips,  
which might have become loose because of temperature fluctuations.  
Humidity  
High-humidity conditions can cause moisture migration and penetration into the  
system. This moisture can cause corrosion of internal components and  
degradation of properties such as electrical resistance and thermal conductivity.  
Extreme moisture buildup inside the system can result in electrical shorts, which  
can cause serious damage to the system.  
Each system is rated to operate at 20 to 85 percent relative humidity, with a  
humidity gradation of 10 percent per hour. Buildings in which climate is  
controlled by air conditioning in the warmer months and by heat during the colder  
months usually maintain an acceptable level of humidity for system equipment.  
However, if a system is located in an unusually humid location, a dehumidifier can  
be used to maintain the humidity within an acceptable range.  
Altitude  
Operating a system at high altitude (low pressure) reduces the efficiency of forced  
and convection cooling and can result in electrical problems related to arcing and  
corona effects. This condition can also cause sealed components with internal  
pressure, such as electrolytic capacitors, to fail or perform at reduced efficiency.  
Each system is designed to operate at a maximum altitude of 6500 feet (2000  
meters) and can be stored at a maximum altitude of 30000 feet (9144 meters).

Appendix B Maintaining the Wide Area Virtualization Engine  
Maintaining Your Site Environment  
Dust and Particles  
A clean operating environment can greatly reduce the negative effects of dust and  
other particles, which act as insulators and interfere with the operation of a  
system’s mechanical components. In addition to regular cleaning, you should  
follow these guidelines to deter contamination of the system equipment:  
Do not permit smoking anywhere near the system.  
Do not permit food or drink near the system.  
Use dust covers when the system is not in use.  
Close windows and outside doors to keep out airborne particles.  
Corrosion  
The oil from a person’s fingers or prolonged exposure to high temperature or  
humidity can corrode the gold-plated edge connectors and pin connectors on  
various devices in the system. This corrosion on system connectors is a gradual  
process that can eventually lead to intermittent failures of electrical circuits.  
To prevent corrosion, you should avoid touching contacts on boards and cards.  
Protecting the system from corrosive elements is especially important in moist  
and salty environments, which tend to promote corrosion. Also, as a further  
deterrent to corrosion, the system should not be used in extreme temperatures, as  
explained in the “Temperature” section on page B-2.  
Electrostatic Discharge  
Electrostatic discharge (ESD) results from the buildup of static electricity on the  
human body and certain other objects. This static electricity is often produced by  
simple movements such as walking across a carpet. ESD is a discharge of a static  
electrical charge that occurs when a person whose body contains such a charge  
touches a component in the system. This static discharge can cause components,  
especially chips, to fail. ESD is a problem particularly in dry environments where  
the relative humidity is below 50 percent.  
To reduce the effects of ESD, you should observe the following guidelines:

Appendix B Maintaining the Wide Area Virtualization Engine  
Maintaining Your Site Environment  
Wear a grounding wrist strap. If a grounding wrist strap is unavailable, touch  
an unpainted metal surface on the chassis periodically to neutralize any static  
charge.  
Keep components in their antistatic packaging until they are installed.  
Avoid wearing clothing made of wool or synthetic materials.  
Electromagnetic and Radio Frequency Interference  
Electromagnetic interference (EMI) and radio frequency interference (RFI) from  
a system can adversely affect devices such as radio and television (TV) receivers  
operating near the system. Radio frequencies emanating from a system can also  
interfere with cordless and low-power telephones. Conversely, RFI from  
high-power telephones can cause spurious characters to appear on the system’s  
monitor screen.  
RFI is defined as any EMI with a frequency above 10 kilohertz (kHz). This type  
of interference can travel from the system to other devices through the power  
cable and power source or through the air like transmitted radio waves. The  
Federal Communications Commission (FCC) publishes specific regulations to  
limit the amount of EMI and RFI emitted by computing equipment. Each system  
meets these FCC regulations.  
To reduce the possibility of EMI and RFI, follow these guidelines:  
Operate the system only with the system cover installed.  
Ensure that the screws on all peripheral cable connectors are securely  
fastened to their corresponding connectors on the back of the system.  
Always use shielded cables with metal connector shells for attaching  
peripherals to the system.  
Magnetism  
Because they store data magnetically, hard disk drives are extremely susceptible  
to the effects of magnetism. Hard disk drives should never be stored near magnetic  
sources such as the following:  
Monitors  
TV sets

Maintaining Your Site Environment  
Printers  
Telephones with real bells  
Fluorescent lights  
Shock and Vibration  
Excessive shock can damage the function, external appearance, and physical  
structure of a system. Each system has been designed to operate properly even  
after withstanding a minimum of six consecutively executed shock pulses in the  
positive and negative x, y, and z axes (one pulse on each side of the system). Each  
shock pulse can measure up to 5 gravities (G) for up to 11 milliseconds (ms). In  
storage, the system can withstand shock pulses of 20 G for 11 ms.  
Excessive vibration can cause the same problems as mentioned earlier for shock,  
as well as causing components to become loose in their sockets or connectors.  
Systems can be subject to significant vibration when being transported by a  
vehicle or when operated in an environment with machinery that causes vibration.  
Power Source Interruptions  
Systems are especially sensitive to variations in voltage supplied by the AC power  
source. Overvoltage, undervoltage, and transients (or spikes) can erase data from  
memory or even cause components to fail. To protect against these types of  
problems, power cables should always be properly grounded and one or both of  
the following methods should be used:  
Use one of the power protection devices described in the “Using Power  
Protection Devices” section on page B-7.  
Place the system on a dedicated power circuit (rather than sharing a circuit  
with other heavy electrical equipment). In general, do not allow the system to  
share a circuit with any of the following:  
Copier machines  
Air conditioners  
Vacuum cleaners  
Space heaters  
Power tools

Using Power Protection Devices  
Teletype machines  
Adding machines  
Laser printers  
Facsimile machines  
Any other motorized equipment  
Besides these appliances, the greatest threats to a system’s supply of power are  
surges or blackouts caused by electrical storms. Whenever possible, turn off the  
system and any peripherals and unplug them from their power sources  
during thunderstorms.  
If a blackout occurs—even a temporary one—while the system is turned on, turn  
off the system immediately and disconnect it from the electrical outlet. Leaving  
the system on may cause problems when the power is restored; all other  
appliances left on in the area can create large voltage spikes that can damage  
the system.  
A number of devices are available that protect against power problems such as  
power surges, transients, and power failures. The following subsections describe  
some of these devices:  
Surge Protectors, page B-7  
Line Conditioners, page B-8  
Uninterruptible Power Supplies, page B-8  
Surge Protectors  
Surge protectors are available in a variety of types and usually provide a level of  
protection commensurate with the cost of the device. Surge protectors prevent  
voltage spikes, such as those caused during an electrical storm, from entering a  
system through the electrical outlet. Surge protectors, however, do not offer  
protection against brownouts, which occur when the voltage drops more than  
20 percent below the normal AC line voltage level.

Appendix B Maintaining the Wide Area Virtualization Engine  
Using Power Protection Devices  
Line Conditioners  
Line conditioners go beyond the overvoltage protection of surge protectors. Line  
conditioners keep a system’s AC power source voltage at a fairly constant level  
and therefore can handle brownouts. Because of this added protection, line  
conditioners cost more than surge protectors—up to several hundred dollars.  
However, these devices cannot protect against a complete loss of power.  
Uninterruptible Power Supplies  
Uninterruptible power supply (UPS) systems offer the most complete protection  
against variations in power because they use battery power to keep the system  
running when AC power is lost. The battery is charged by the AC power while it  
is available, so once AC power is lost, the battery can provide power to the system  
for a limited amount of time—from 15 minutes to an hour or so—depending on  
the UPS system.  
UPS systems range in price from a few hundred dollars to several thousand  
dollars, with the more expensive units allowing you to run larger systems for a  
longer period of time when AC power is lost. UPS systems that provide only  
5 minutes of battery power let you conduct an orderly shutdown of the system but  
are not intended to provide continued operation. Surge protectors should be used  
with all UPS systems, and the UPS system should be Underwriters Laboratories  
(UL) safety-approved.
