Overview  
The Hewlett-Packard SureStore E hub, short-wave model S10 and long-wave model L10, is  
a full-duplex, 1063-megabit-per-second hub. It increases loop reliability, number of loop  
connections, and distances between server and mass storage devices in a Fibre Channel  
Arbitrated Loop. The hub’s port detection and bypass circuitry dynamically detects and  
bypasses a failed node on the loop. Nodes can be added, removed, and reconnected  
without bringing down the loop and disrupting communication for other nodes.  
Fibre Channel Manager is a web-based software application that allows you to remotely  
manage and monitor the health of the hub. To learn more about Fibre Channel Manager,  
visit the Hewlett-Packard (Software Depot (http://www.software.hp.com). Fibre Channel  
Manager is available as a free download from this web site.  
Older hubs may require a firmware upgrade to meet Fibre Channel Manager’s minimum  
requirements. The Software Depot web site has more information about this. The latest  
hub firmware and upgrade instructions are available as a free download from this web site.  
Detailed configuration information and part numbers for the hub are provided in chapter 6,  
Reference.

Features  
HP SureStore E hubs provide the following features:  
Short-wave hub (model S10): 10 non-Open Fibre Control (non-OFC) short-wave  
optical transceivers  
Long-wave hub (model L10): nine non-OFC, short-wave optical transceivers and one  
non-OFC, long-wave optical transceiver  
Local retime and regeneration of transmit signals to prevent accumulation of jitter and  
improve the signal  
Reliable, automatic bypass of failed nodes; dynamic recognition of newly added or  
removed nodes, with a controller in each port permitting the bypass of a port if the port  
fails signal validity tests  
Active loop reconfiguration when a node to an arbitrated loop is added, removed, or  
moved  
Plug-and-play capability, which allows the hub to connect to compatible servers and  
other Fibre Channel Arbitrated Loop (FC-AL) devices while they are operating ( FC-AL  
devices can be added or removed while the hub is active.)  
Cascade support (hub-to-hub connections) for increased loop distances  
Cascaded short-wave hubs are supported up to 500 meters; cascaded long-wave hubs  
are supported up to 3000 meters (3 km). Under certain conditions, cascaded long-wave  
hubs are supported up to 10,000 meters (10 km) (see page 105 for more information).  
The 10-km capability only applies to long-wave hubs connected to HP-UX servers.

Supported Topologies  
Devices such as FC-AL disk arrays and HP system servers that support FC-AL can be  
connected to the hub in a loop that includes one or more servers. All nodes in the loop  
must be 1063 Mbps short-wave, non-OFC, FC-AL. The ports connected by a cable must  
have the same optical transceivers. Figure 4, Figure 5, and Figure 6 show typical hub  
topologies. For details on supported topologies, contact an HP sales representative.  
Single Short-Wave Hub Topology  
For the model S10 short-wave hub, Hewlett-Packard recommends 50-micron multimode  
fiber cable for new installations, but also supports 62.5-micron multimode fiber cable with  
SC-style connectors in existing installations. Stated distances assume 50-micron multimode  
cable.  
A server with an FC-AL short-wave adapter can connect to an hub 500 meters away. Each  
of the 10 ports on the short-wave hub can connect to an FC-AL device up to 500 meters  
away. The maximum distance between the server and the end FC-AL device is 1000 meters  
(1 km).

Cascaded Short-Wave Hub Topology  
The example in Figure 5 shows two model S10 hubs connected in a cascade topology.  
Cascaded short-wave hubs use one port on each hub for the hub-to-hub connection. Such a  
configuration increases the potential distance between nodes in the loop an additional 500  
meters. The maximum distance between the server and FC-AL devices with cascaded  
short-wave hubs is 1500 meters (1.5 km).

Cascaded Long-Wave Hub Topology  
Cascaded FC-AL, non-OFC, model L10 long-wave hubs use the long-wave port for the hub-  
to-hub connection. The maximum supported distance between cascaded long-wave hubs  
with single-mode 9 micron cable is 3 km. The maximum distance between a server and FC-  
AL devices on cascaded long-wave hubs is, therefore, 4000 meters (500 m + 3000 m +  
500 m). Under certain conditions, cascaded long-wave hubs are supported up to 10,000  
meters (10 km) (see page 105 for more information). The 10-km capability only applies to  
long-wave hubs connected to HP-UX servers.  
Caution  
When cascading long-wave hubs, only connect long-wave ports to long-wave  
ports or short-wave ports to short-wave ports.  
Ports 1 through 9 on each long-wave hub are for connections to FC-AL devices. Ports 1  
through 9 can also be used in a cascaded configuration; however, the maximum distance  
between hubs decreases from 3000 meters to 500 meters.

Procedure 3: Verify Hub Operation  
By performing this procedure, you test the hub and verify that it operates properly before  
you mount it in a rack or connect any devices to it.  
1. To initialize the self-test, first plug the power cord into the hub and then into a power  
receptacle. The hub does not have a power switch.  
The hub runs the self-test each time the power cord is plugged in or the Reset button is  
pressed.  
Note  
The hub’s power supply automatically adjusts to a range of 100 VAC ±10% or  
240 VAC ±10%.  
2. The hub finishes the self-test in less than 15 seconds.  
If the Fault LED (amber) stays on after self-test, the hub failed. Refer to chapter 4,  
Troubleshooting, or contact an HP service representative for assistance.  
If the Power LED does not light, refer to chapter 4, Troubleshooting, or contact an HP  
service representative.  
Note  
Interruptions to the hub’s AC power source initiate a self-test. Make sure the  
power source circuits are properly grounded before using the supplied power  
cord to connect the hub to the circuit.  
3. Verify that each Fibre Channel port is operating properly. Insert the loopback cable into  
the port and verify that the port status LED turns on. Both ends of the loopback cable  
plug into the port connectors.  
If you plan to use Fibre Channel Manager to manage the hub, continue with step 4. If you  
do not plan to use Fibre Channel Manager or another hub management tool, go to step 7.  
Procedure 3: Verify Hub Operation  
25

4. Verify that the 10Base-T port is operating properly. Insert an ethernet cable that is  
connected to the LAN into the 10Base-T port, and verify that the 10Base-T status LED  
turns on. (The status LED may begin flashing.)  
5. Set the hub IP address and configure the hub as described in chapter 3, RS-232 Interface  
Functions.  
6. Verify the connection between the HP-UX server and the hub. At the management server  
where Fibre Channel Manager is or will be installed, execute the following command:  
/etc/ping <hub IP address>  
Example: /etc/ping 15.43.214.13  
Fibre Channel Manager requires HP-UX 10.20 or 11.0 on the management server.  
If you are unable to ping the hub, refer to If the Management Server Cannot Ping the  
Hub on page 78.  
7. Unplug the hub.

Procedure 4: Mount the Hub into a Rack (Optional)  
The hub mounts into any standard HP 19-inch wide EIA cabinet. The hub’s front panel will  
face the rear of the cabinet. The front of the hub contains the 10 Fibre Channel connectors.  
You will need a T25 Torx head screwdriver to complete this procedure.  
1. Record the serial number, located on the bottom of the hub, and the MAC address,  
located under the 10Base-T port. The MAC address is unique and cannot be changed.  
2. Verify that the rack is adequately secured and has enough space (1 EIA) for the hub.  
Remove filler panels as needed from the front of the cabinet and open the rear door.  
3. If the rubber feet are attached to the bottom of the hub, peel off the feet. Attach the  
mounting ear brackets and nylon retainers if they are missing from the left and right  
sides of the hub (Figure 8).  
Secure the mounting ear brackets with three M3 x .5 screws to each front outside  
corner, turning the angled end of the bracket outward. Attach the nylon retainers with  
one screw through the center of the retainer and into the hole in each side of the hub.

Procedure 5: Plan the FC-AL Connections  
The hub does not require drivers or specific versions of operating systems. However,  
systems and FC-AL devices that can connect to the hub do have driver and operating  
system requirements. Contact an HP sales representative for information on hardware and  
software requirements for the systems or FC-AL devices you plan to connect to the hub.  
The HP Fibre Channel Manager User Manual lists operating system requirements for  
Fibre Channel Manager.  
1. Verify that the loop cabling configuration is correct by comparing it to the cabling  
examples on the following pages. Modify the network cabling map as needed.  
Caution  
Incorrect wiring can lead to problems such as devices left off the loop and  
inaccessible by the server. Follow the guidelines below before starting.  
2. Refer to your cabling map to review the user-assigned loop ID (hardware address) of  
each FC-AL device to be connected to the hub, and verify that each ID is unique.  
Duplicate IDs on the loop can cause problems.  
3. Verify that the connections between the hub port and the FC-AL mass storage device or  
the FC-AL adapter are of the same wave type and speed. For example, plan to connect  
a short-wave port on the hub to a short-wave port on an FC-AL device.  
4. Document the planned connections in a cabling map.  
Correct Cabling Example for a Short-Wave Hub  
For the model S10 short-wave hub, Hewlett-Packard recommends 50-micron multimode  
fiber cable for new installations but also supports 62.5-micron multimode fiber cable with  
SC-style connectors in existing installations.

Procedure 5: Plan the FC-AL Connections  
Download from Www.Somanuals.com. All Manuals Search And Download.  
In a cascaded configuration of model S10 short-wave hubs, connect any port on the first  
hub to any port on the second hub. Figure 13 includes all 18 nodes in the loop formed by  
FC-AL Device 1, Hub A, Hub B, and FC-AL Device 2:  
Port 1 on Hub A connects to FC-AL Device 1.  
Port 10 of Hub A connects to Port 1 of Hub B.  
Port 10 on Hub B connects to FC-AL Device 2.  
In this configuration, any unused port on Hub A or Hub B can connect to any compatible  
FC-AL device. This is just one example of cascaded short-wave hubs. The connection  
between short-wave hubs can occupy any combination of ports.

Note  
If you plan to use Fibre Channel Manager to manage cascaded hubs, you must  
configure the hub that has the LAN (ethernet) connection as a parent hub and  
the remaining hub as a child hub (see Configuring Cascaded Hubs on page 60).  
Correct Cabling Example for a Long-Wave Hub  
Hewlett-Packard recommends 9-micron, single-mode fiber cable for the long-wave port.  
For ports 1 through 9, the short-wave ports, Hewlett-Packard recommends 50-micron  
multimode fiber cable for new installations but also supports 62.5-micron multimode fiber  
cable with SC-style connectors in existing installations.  
Procedure 5: Plan the FC-AL Connections

Download from Www.Somanuals.com. All Manuals Search And Download.  
In a cascaded configuration of FC-AL long-wave hubs, connect the long-wave port on the  
first hub to the long-wave port on the second hub. Figure 14 shows all 18 nodes in the loop  
formed by FC-AL Device 1, Hub A, Hub B, and FC-AL Device 2:  
Port 1 on Hub A connects to FC-AL Device 1.  
The long-wave port of Hub A connects to the long-wave port of Hub B.  
Port 1 on Hub B connects to FC-AL Device 2.  
Long-wave hubs can be cascaded with ports 1 through 9 (the short-wave ports), but the  
supported distance between hubs is reduced from 3000 meters to 500 meters. When  
cascading long-wave hubs, ONLY connect long-wave ports to long-wave ports or short-  
wave ports to short-wave ports. Any unused short-wave port on Hub A or Hub B can  
connect to any compatible FC-AL device.

Procedure 6: Connect FC-AL Devices  
After the hub and devices are prepared, connect FC-AL devices as follows:  
1. Physically set each FC-AL device to a unique loop ID (hardware address). Refer to the  
FC-AL device’s manual to set the loop ID.  
If devices are added during normal operation and duplicate IDs occur, the Fibre  
Channel driver denies access to both devices until the address conflict is resolved.  
Change the address of the second (duplicating) device.  
If devices are added or device addresses changed while the system is powered off  
and duplicate IDs occur, the system is unavailable until the address conflict is resolved.  
An error message appears on the system console. Change the address of the second  
(duplicating) device.  
2. Remove the covers from the FC-AL ports. Refer to your cabling map, and begin  
connecting devices to the hub. Leave the covers on ports not in use.  
Caution  
Fiber optic cables and connectors are extremely fragile. Avoid twisting or  
bending the cable beyond a 3-cm radius.  
If the hub and all FC-AL devices are powered down, first plug in the hub, then  
power on the devices at all the FC-AL nodes on the loop. The hub should be the first  
operating component in the loop.  
If the hub and all devices are powered up, you can connect the hub to a server or  
FC-AL device while the server or FC-AL device is operating.

Procedure 6: Connect FC-AL Devices  
Download from Www.Somanuals.com. All Manuals Search And Download.  
If the hub is to be connected to an FC-AL adapter that is connected to another FC-AL  
device, follow the removal procedures in the document that came with the FC-AL  
device before disconnecting the device’s cable.  
If the hub is to be connected to an FC-AL device that is connected directly to a server,  
follow the removal procedures in the document that came with the FC-AL device  
before disconnecting the device’s cable.  
When installing model L10 long-wave hubs in a cascaded topology, make sure the  
long-wave port is connected only to the long-wave port on another long-wave hub.  
3. For the model L10 long-wave hub, connect the long-wave loopback cable to the  
long-wave port if the port is not in use.  
4. Install any special files the FC-AL devices need. Refer to the device manual for details.

Download from Www.Somanuals.com. All Manuals Search And Download.  
Procedure 7: Verify the Connections  
After connecting devices and the server to the hub, verify the connections.  
Note  
Because the hub is strictly a pass-through device for FC-AL traffic, there is no  
hub address and the hub is not listed in ioscan output (HP-UX servers) or the  
SCSI Adapters window (HP NetServers).  
For HP-UX servers:  
1. Use the following HP-UX command to run ioscan and check the hardware paths  
between the server and the attached FC-AL devices:  
ioscan -f  
For details on ioscan and its options, refer to the HP-UX System Administration  
Tasks Manual. Also consult the device documentation to interpret the ioscan output.  
2. If the Hardware State of a device connected to the hub is “Unclaimed” or “No H/W,” see  
chapter 4, Troubleshooting, for more information.  
For HP NetServers:  
1. From the Start menu, select Settings, then select Control Panel.  
2. Double-click the SCSI Adapters icon. The SCSI Adapters window appears.  
3. Click the Devices tab, then verify that the FC-AL devices connected to the hub are  
displayed.

Overview  
This chapter describes how to use the RS-232 port to update firmware, enable hub  
management, run diagnostic tests, and view hub information. The RS-232 port is located on  
the front panel of the hub (see Figure 1 on page 14 or Figure 2 on page 15).  
To configure the hub for Fibre Channel Manager or another management application, use  
the hub’s configuration menus to set SNMP values and the IP address.  
If you do not plan to manage the hub with Fibre Channel Manager or another management  
application, you do not have to update the firmware or enable hub management. You do not  
have to update hub firmware to run diagnostic tests or view hub information.  
Before beginning the procedures in this chapter, determine the configuration values that  
are required for the hub. Obtain IP addresses from the network administrator for the LAN  
to which the parent hub is connected. IP addresses are optional for the child hub. Values  
can be written in the spaces of the following worksheet.

Setting Up an RS-232 Connection  
The RS-232 interface requires a connection from the hub to a dumb terminal or to a PC with  
a terminal emulator program. A PC is required for updating firmware. To access the hub  
configuration menus, you can use either a PC or a dumb terminal.  
Setting Up a Connection to a PC  
Setting up a PC connection requires the following equipment:  
FC-AL hub  
A personal computer, such as an OmniBook notebook PC  
A null-modem serial cable  
The cable must have a DB-9 female connector for connection to the hub. For example,  
for an OmniBook notebook PC, you can use an HP 24542U RS-232 cable, which has  
two DB-9 female connectors.  
Terminal emulation software, such as HyperTerminal  
The terminal emulator must be capable of ASCII text file transfers and support VT100  
or ANSI emulation with no flow control.  
To establish a connection, do the following:  
1. Connect the serial cable between the RS-232 port on the hub and a serial (COM) port on  
the PC.

Updating the Hub Firmware  
The hub’s management tool, Fibre Channel Manager, requires the following versions of hub  
firmware: .  
Device Agent  
Hub Controller  
02.14 (or higher)  
03.06 (or higher)  
Before you begin this procedure, determine whether the hub requires a firmware update to  
communicate with Fibre Channel Manager. A label on the bottom of the hub chassis lists  
the EDC datecode. If the EDC datecode is C-38XX or higher, the hub has the required  
firmware.If you are not able to access the label, determine the firmware versions by  
connecting to the hub’s RS-232 interface (see Setting Up an RS-232 Connection on page 45).  
To update the hub firmware, use a PC connected to the hub. First copy the firmware files to  
the PC and then transfer the firmware from the PC to the hub.  
The general process for updating the hub firmware is the following:  
1. Obtain the current firmware.  
2. Reboot the hub.  
3. Update the hub controller firmware.  
4. Update the hub device agent code.  
5. Reset the hub.  
6. Set manufacturing values.  
If any hubs are cascaded, repeat the procedures for each child hub. Parent and child hubs  
must have identical versions of the firmware.  
The procedures in this section require a total of 30 to 60 minutes to complete.

self-test, an error number is displayed; for example:  
Status of Hub Controller self-test:  
0200  
A value of 0200 in the self-test represents a fan failure. Replace the fan module as  
described in Replacing the Fan Module on page 88.  
Any other numeric value represents an internal hub failure. Internal parts are not  
replaceable. If an internal malfunction occurs, replace the hub.  
WARNING  
Do not attempt to open the hub chassis. Uninsulated parts inside the  
chassis constitute a hazard.  
3. After correcting any problems, enter 1 to reset the hub.

Troubleshooting Procedures  
If there is a problem accessing a device connected to the hub, the source of the problem  
can be with the device, the hub, the host, or any of the connections between the host and  
the device. Follow the steps below to investigate the problem from the most likely to the  
least likely cause. In addition, check the troubleshooting tables in this chapter for solutions  
to specific symptoms.  
1. For HP-UX servers, run ioscan from the server’s console.  
If the hardware paths for all FC-AL devices connected to the hub are listed in ioscan,  
the connection from the host to the device is good, and problems accessing a device  
probably originate in the software, driver, or device.  
If the hardware path for a FC-AL device connected to the hub is not listed in ioscan,  
the source of the problem is likely to be bad connections, duplicate hardware  
addresses, a faulty device, or a faulty hub (see steps 2 through 5). The hub does not  
appear in ioscan output because it does not have a hardware address.  
For HP NetServers, open the SCSI Adapters window, then click the Devices tab. If  
the device is not displayed, the problem is likely to be bad connections, duplicate  
hardware addresses, a faulty device, or a faulty hub (see steps 2 through 5). The hub  
does not appear in this window because it does not have a hardware address.  
2. Inspect the cabling between the hub and FC-AL devices. Check for loose, dirty,  
broken, or bent cabling and connectors. Cables should attach with an audible click.  
3. Check the loop ID (hardware address) of each device on the loop and eliminate  
any duplicate addresses. Reset the hub after changing any loop ID, then run ioscan to  
make sure there are no duplicate addresses. Duplicate addresses can be indicated by  
“NO H/W” in the S/W State field.  
4. Inspect the FC-AL device for a fault. Follow the instructions that came with the  
device. Make sure you check the fiber optic transmit or receiving port on the device.  
5. Inspect the hub LED indicators for apparent problems (see Table 2 on page 70). If  
the Fault LED is lit, either the fans or the hub is faulty. If a cable is connected to a port  
68  
Troubleshooting Procedures

and the corresponding port LED is not lit, try replacing the cable with a loopback cable  
to determine if the problem is with the cable or the port. For the long-wave hub, use the  
long-wave loopback cable (A4839-63001) if you are testing the long-wave port.

Introduction  
This chapter explains how to maintain the hub and replace the fan module. The fan module  
is the only replaceable part on the hub. To identify the source of a problem, see chapter 4,  
Troubleshooting.  
WARNING  
Do not attempt to open the hub chassis. Uninsulated parts inside the  
chassis constitute a hazard.  
86  
Introduction  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Maintenance  
Good system performance requires clean port optics and cable ferrules to avoid  
obstructing the optical path. The following preventive maintenance will protect the hub for  
longer use.  
Vacuum to remove dust.  
Leave the FC port covers on unused FC ports.  
Replace the fan module every three years.  
Avoid dropping fiber optic cable ends. This can cause internal glass fractures and  
intermittent signals.  
Keep unused cable ends covered to avoid contaminant-obscured or attenuated light  
signals.  
Never insert foreign objects into the optical transmit and receive ports.  
Avoid bending fiber cables over more than a 3-cm bend radius.  
When a faulty connection is suspected, blowing clean compressed air on the FC port and  
cable end often is sufficient to remove dirt particles. Cleaning the connectors with  
methanol on a lint-free cloth is also effective. Alcohols that can be used include methyl,  
isopropyl, and isobutyl. Other acceptable substances for cleaning fiber optics are hexane  
and heptane aliphatics, soap solution, and naphtha.  
Caution  
DO NOT use partially halogenated hydrocarbons, ketones, acetone,  
chloroform, ethyl acetate, methylene dichloride, phenol, methylene chloride, or  
N-methylpyrolldone to clean the connectors.

Replacing the Fan Module  
The three fans in the fan module operate in parallel. If one fan fails, the other two will  
continue to operate. However, it is important to replace the fan module immediately.  
Replace the fan module at least once every three years.  
You will need the following tools:  
Standard Phillips screwdriver  
Fan module (A3724-60002)  
WARNING  
The power cord is the main disconnect for this product. To protect  
against hazard, always unplug the AC power cord before removing  
the fan module.  
1. Relocate or power off devices connected to the hub as needed to prepare for powering  
off the hub.  
2. Unplug the power cord from the hub.  
3. Using a standard Phillips screwdriver, remove the four screws that secure the fan  
module. Sheet metal marks indicate the location of the screws on the top and sides of  
the hub.

systems and FC-AL devices that can connect to the hub do have driver and operating  
system requirements. Contact an HP sales representative for information on hardware and  
software requirements for the FC-AL devices you plan to connect to the hub.  
Physical and Cabling Requirements  
Note  
For short-wave ports, SC Connectors must be AMP multimode #504657-1 or  
equivalent to meet FCC Part 15 standards. For long-wave ports, SC Connectors  
must be AMP single-mode #504655-1 or equivalent to meet FCC Part 15  
standards. Cable Plant Specifications on page 101 lists more requirements.  
Model S10 Short-Wave Hub  
The short-wave hub supports 10 non-OFC, short-wave FC-AL connections. In arbitrated  
loop topology, data rates and wavelength between ports must be the same. The short-wave  
hub supports only gigabit short-wave to gigabit short-wave connections using fiber cables.  
For the short-wave hub, Hewlett-Packard recommends 50-micron multimode fiber cable  
for new installations but also supports 62.5-micron multimode fiber cable with SC-style  
connectors in existing installations. Installations can mix 50-micron and 62.5-micron  
cables.  
Model L10 Long-Wave Hub  
The long-wave hub supports short-wave gigabit to short-wave gigabit connections from  
ports 1 through 9 using fiber cables. The long-wave hub also supports a long-wave hub to  
long-wave hub connection from the long-wave port.

For the long-wave port, Hewlett-Packard recommends 9-micron single-mode fiber  
cable.  
For ports 1 through 9, Hewlett-Packard recommends 50-micron multimode fiber cable  
for new installations but also supports 62.5-micron multimode fiber cable with SC-style  
connectors in existing installations.  
Cable Plant Specifications  
The cable plant includes losses of the fiber and splices and connectors (excluding those at  
the ends of the link that are accounted for in the transmitter and receiver specifications).

HP suggests that the loss of a new single-mode cable plant be limited to 6dB or lower in  
order to maximize the probability that the cable plant will permit 10- km operation with  
the majority of long-wave hubs (HP-UX servers only). Larger losses are permissible if the  
receiver power is greater than -17dBm. For new installations, HP recommends that the  
single-mode fiber be low-loss fiber equivalent to Corning’s premium grade of their single-  
mode SMF-28 cable with loss of 0.35 dB/km or lower in order to more easily attain the  
required signal power at the receiver in spite of losses due to connectors and splices.

Model L10 Long-Wave Hub  
Note  
Stated distances assume 9-micron single-mode cable for the long-wave port and  
50-micron multimode cable for the short-wave ports.  
For ports 1 through 9, the long-wave hub supports distances of 500 meters between the  
port and a connected FC-AL device. For the long-wave port, the long-wave hub supports  
distances up to 3 kilometers between two long-wave hubs. Under certain conditions,  
cascaded long-wave hubs are supported at distances up to 10 kilometers. The 10-km  
capability is supported only for long-wave hubs connected to HP-UX servers.  
To verify 10-km capability for the long-wave hub over an existing cable plant:  
The received average optical power of the long-wave port on both long-wave hubs must be  
higher (more positive) than -17 dBm in order for the long-wave hubs to support cascade  
distances of up to 10 km. Use an optical power meter that measures average optical power  
at a wavelength of 1300 nm in dBm units (for example, the Fotec Model 712A Power Meter  
with Model A262 SC connector adapter).  
To verify the long-wave port’s received average optical power, do the following:  
1. Power on both long-wave hubs and connect the long-wave ports with the 10-km single-  
mode cable.  
2. Turn the optical power meter on. The meter performs a self-test.  
3. If necessary, set the meter’s wavelength to 1300 nm and measuring units to dBm.  
4. Disconnect the Fibre Channel cable from the long-wave port of one of the two hubs.  
5. Determine which connector of the Fibre Channel cable is the transmitter. Connect one  
plug of the Fibre Channel cable into the SC receptacle of the meter. If the meter does  
not indicate a signal, connect the other plug of the Fibre Channel cable.  
6. Verify that the reading on the meter is higher (more positive) than -17 dBm and lower  
than -3 dBm.  
7. Reconnect the Fibre Channel cable to the long-wave port.  
8. Repeat steps 4 through 7 with the long-wave port of the second long-wave hub.

If both ends of the Fibre Channel cable are between the limits listed in step 5, the two  
long-wave hub’s are verified for cascading up to 10 km using this cable plant. If the meter  
readings are not within range, verify that the Fibre Channel cable is securely connected to  
the hub’s long-wave port. Also verify, that the cable connectors are clean by wiping them  
with a lint-free cloth dampened with reagent grade isopropyl alcohol and blowing the  
connectors dry with clean, compressed air.

GLOSSARY  
Arbitrated Loop  
See Fibre Channel - Arbitrated Loop.  
Child Hub  
The HP SureStore E short-wave and long-wave hubs support a cascaded topology. In a  
cascaded hub topology, the child hub is the hub that is not connected to the LAN  
(ethernet). HP SureStore E hubs are configured as a parent or child hub through their  
RS-232 interface.  
Device

Fibre Channel  
Logically, Fibre Channel is a bidirectional, full-duplex, point-to-point, serial data  
channel structured for high performance capability. Physically, the Fibre Channel is an  
interconnection of multiple communication ports, called NL_Ports, interconnected by a  
switching network, called a fabric, a point-to-point link or an arbitrated loop. Fibre  
Channel is a generalized transport mechanism that has no protocol of its own or native  
input/output command set, but can transport any existing Upper Level Protocols  
(ULPs) such as SCSI and IPI at speeds of 100 Mbytes/sec over distances of up to 10  
kilometers over optical links. Fibre Channel can interconnect two devices in a point-to-  
point topology, from two to 126 devices in an arbitrated loop, and up to 224 devices in a  
fabric switched topology.  
Fibre Channel Arbitrated Loop (FC-AL)  
One of three existing Fibre Channel topologies in which two to 126 devices are  
interconnected serially in a single loop circuit without hubs and switches.  
Communication is managed using an arbitration process in which the lowest port  
address has the highest priority for communicating. The arbitrated loop topology  
supports all classes of service and guarantees in-order delivery of frames when the  
source and destination are on the same loop.  
Link  
For Fibre Channel, a connection between two nodes, each having at least one N_Port,  
interconnected by a pair of optical or copper links, one inbound and one outbound.  
Long Wave  
Lasers or LEDs that emit light with wave lengths around 1300 nm. Long-wave lasers are  
used for long Fibre Channel links, from 700 to 2000 meters. They are typically used with  
single-mode fiber of a 9-micron core size.  
Loop Address  
The unique ID of a node in Fibre Channel loop topology, sometimes referred to as a loop  
ID.  
118  
Glossary  
Download from Www.Somanuals.com. All Manuals Search And Download.  
N_Port  
A “Node” port. A Fiber Channel-defined hardware entity that performs data  
communication over the FC-AL link. It is identifiable by a unique World Wide Name. It  
can act as an originator or a responder.  
N_Port Identifier  
A unique address identifier by which an N_Port is uniquely known. It consists of a  
Domain (most significant byte), an Area, and a Port, each 1-byte long. The N_Port  
identifier is used in the Source Identifier (S_ID) and Destination Identifier (D_ID) fields  
of an FC-AL frame.  
Parent Hub  
The HP SureStore E short-wave and long-wave hubs support a cascaded topology. In a  
cascaded hub topology, the parent hub is the hub that is connected to the LAN  
(ethernet). HP SureStore E hubs are configured as a parent or child hub through their  
RS-232 interface.  
Short Wave  
Lasers or LEDs that emit light with wave lengths around 780 nm or 850 nm. Short-wave  
lasers are used for FC-AL links up to approximately 700 meters. They are typically used  
with multimode fiber. The preferred fiber core size is 50 micron because this fiber has  
large bandwidth so that the distance is limited by the fiber attenuation. A 62.5-micron  
core size is also supported for compatibility with existing FDDI installations. Fiber of  
this type has smaller bandwidth and, in this case, the distance is limited by the fiber  
bandwidth.  
Topology  
The physical or logical layout of nodes on a network. FC-AL topologies include point-to-  
point, FC-AL, and fabric. The hub supports FC-AL topology.
