Overview  
The Brocade 6910 Ethernet Access Switches are carrier grade access switches that meet the  
requirements for nonstop networking with Layer 2 services. Each platform provides dual power  
input for redundancy and has been architected with the state of the art hardware design and field  
proven operating system for reliability and resiliency. Brocade 6910 switches support multiple fiber  
or copper configurations on a single switch using a 12 Gigabit combination RJ-45/SFP ports.  
Brocade 6910 allows the same ports to be configured to connect directly to the customer or as  
network interface on the service side. This ideally positions the Brocade 6910 at the edge of a  
broadband access network for Ethernet service demarcation, extension and aggregation.

Switch Architecture  
These switches employ a wire-speed, non-blocking switching fabric. This permits simultaneous  
wire-speed transport of multiple packets at low latency on all ports.  
Network Management Options  
These switches contain a comprehensive array of LEDs for “at-a-glance” monitoring of network and  
port status. They also include a management agent that allows you to configure or monitor the  
switch using its embedded management software, or through SNMP applications. To manage the  
switch, you can make a direct connection to the console port (out-of-band), or you can manage the  
switch through a network connection (in-band) using Telnet, SSH, the on-board web agent, or  
SNMP-based network management software.  
The switch management port (RJ-45) provides a dedicated management channel that operates  
outside of the data transport network. This makes it possible to re-configure or troubleshoot the  
switch over either a local or remote connection to the port when access through the data channel is  
not possible or deemed insecure.  
For a detailed description of the switch’s advanced features, refer to the Brocade 6910 Ethernet  
Access Switch Configuration Guide.

BR-6910-EA-H-DC  
SFP Slots  
The 12 Small Form Factor Pluggable (SFP) transceiver slots are shared with 12 RJ-45 ports. In its  
default configuration, if an SFP transceiver (purchased separately) is installed in a slot and has a  
valid link on its port, the associated RJ-45 port is disabled and cannot be used. The switch can also  
be configured to force the use of an RJ-45 port or SFP slot, as required.  
There are two types of SPF transceivers - one hardened that can operate at temperatures between  
-40 to +65 °C, and non-hardened that can operate at temperatures between 0 to +50 °C.  
The SFP slots support the following SFP transceivers:

10/100/1000BASE-T Ports  
The switches contain 12 1000BASE-T RJ-45 ports that operate at 10 Mbps or 100 Mbps, half or full  
duplex, or at 1000 Mbps, full duplex. Because all of the RJ-45 ports support automatic MDI/MDI-X  
operation, you can use straight-through cables for all network connections to PCs or servers, or to  
other switches or hubs. (See “1000BASE-T Pin Assignments” on page 29.)  
Each of these ports support auto-negotiation, so the optimum transmission mode (half or full  
duplex), and data rate (10, 100 or 1000 Mbps) can be selected automatically. If a device  
connected to one of these ports does not support auto-negotiation, the communication mode of  
that port can be configured manually. Each port also supports auto-negotiation of flow control, so  
the switch can automatically prevent port buffers from becoming saturated.  
10/100/1000BASE-T Management Port (The Craft Interface)  
The 10/100/1000BASE-T port provides a dedicated management interface that is segregated  
from the data traffic crossing the other ports. This port supports auto-negotiation, so the optimum  
transmission mode (half or full duplex) and data rate (10, 100, or 1000 Mbps) can be selected  
automatically, if this feature is also supported by the attached device. However, note that the  
interface connection parameters of this port cannot be configured.  
Console Port  
The console port on the switch’s front panel is an RJ-45 connector that enables a connection to a  
terminal for performing switch monitoring and configuration functions. The terminal may be a PC or  
workstation running terminal emulation software, or a terminal configured as a Data Terminal  
Equipment (DTE) connection. A null-modem wired serial cable is supplied with the switch for  
connecting to this interface.  
It is recommended that you use the cable provided with the box.  
Flow control must be disabled to use the console port and port speed is 9600-N-8-1  
Alarm Interface Port  
The DB-15 alarm port on the switch’s front panel can be used to provide alarm, service port, and  
BITS clock reference interfaces. The switch supports two sets of alarm relay contacts (major and  
minor), and 4 external customer site alarm inputs. It also provides an alarm cutoff button (labeled  
ACO). Refer to “Connecting to the Alarm Port” on page 20 for a description of the pin assignments  
used to connect to the alarm port.  
Port and System Status LEDs  
This switch includes a display panel for key system and port indications that simplifies installation  
and troubleshooting. The LEDs, which are located on the front panel for easy viewing, are shown  
below and described in the following tables.

Installing an Optional SFP Transceiver  
FIGURE 13 INSTALLING AN OPTIONAL SFP TRANSCEIVER  
These switches support SFP-compatible transceivers. To install an SFP transceiver, do the  
following:  
1. Consider network and cabling requirements to select an appropriate SFP transceiver type.  
2. Insert the transceiver with the optical connector facing outward and the slot connector facing  
down. Note that SFP transceivers are keyed so they can only be installed in one orientation.  
3. Slide the SFP transceiver into the slot until it clicks into place.  
NOTE  
SFP transceivers are hot-swappable. The switch does not need to be powered off before installing  
or removing a transceiver. However, always first disconnect the network cable before removing a  
transceiver.  
NOTE  
SFP transceivers are not provided in the switch package.  
Grounding the Chassis  
Before powering on the switch, ground the switch to earth as described below.  
1. Ensure that the rack on which the switch is to be mounted is properly grounded and in  
compliance with ETSI ETS 300 253.  
2. Ensure that there is a good electrical connection to the grounding point on the rack (no paint or  
isolating surface treatment).  
3. Disconnect all power cables to the switch.

Connecting to a Power Source  
2
Connecting DC Power  
When using 20-60Vdc power, an external DC power supply must be connected to the DC power  
connector on the left side of the front panel. DC input (DC source) must be isolated from AC mains  
by reinforced insulation.  
DANGER  
Remove both power cords before servicing.  
NOTE  
To provide adequate circuit protection between the DC power supply and the switch, all intermediate  
wiring and circuitry should be rated to carry a load at least two times the maximum rating for this  
switch (see “Power Supply” on page 32.)  
NOTE  
For a DC system, use a grounding wire of at least 18 American Wire Gauge (AWG). The 18 AWG wire  
should be attached to an agency-approved crimp connector (provided on the chassis), and crimped  
with the proper tool. The crimp connector should allow for securement to a ground screw on the  
enclosure.  
NOTE  
Wiring for the power input terminals on the switch are described below. Wiring of the DC power  
supply terminals depends on the equipment in use on the local site, but should be wired in such a  
way as to meet the input requirements shown in “DC PLUG CONNECTIONS” on page 16. The wiring  
should also be color coded according to local standards to ensure that the input power and ground  
lines can be easily distinguished.  
To connect the switch to a power source:  
1. First verify that the DC power can provide 20-60Vdc, 1.9A.  
2. Prepare two wires for each power source to be used. Use 18 AWG stranded copper wire. Make  
sure these wires are not plugged into the power source.  
3. Use a wire stripper to carefully strip about a half an inch of the outer insulation off the end of  
each wire, exposing the copper core.  
4. Twist the copper wire strands together to form a tight braid. If possible, solder the exposed  
braid of wire together for better conductivity.  
5. Connect the external power feed and power ground/return lines to the DC plug (provided with  
the switch) as shown in the following figure. The plugs are labeled on the front of the chassis,  
above the DC power connection block. The -48 VDC power feed uses the “-48VDC” input lines.  
Use a small flat-tip screwdriver to loosen the screws on the power plug and open the wire  
clamps.  
This equipment installation must meet NEC/CEC code requirements. Consult local authorities for  
regulations.

Connecting Network Devices  
These switches are designed to connect broadband access network devices to aggregation  
network devices in the service provider CO. It can connect to twisted-pair devices through its RJ-45  
ports, or to fiber-optic devices through SFP transceivers.  
Twisted-Pair Devices  
Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends.  
Use Category 5, 5e or 6 cable for 1000BASE-T connections.  
Cabling Guidelines  
The RJ-45 ports on the switch support automatic MDI/MDI-X pinout configuration, so you can use  
standard straight-through twisted-pair cables to connect to any other network device (PCs, servers,  
switches, routers, or hubs). See “Twisted-Pair Cable and Pin Assignments” on page 27 for further  
information on cabling.  
CAUTION  
Do not plug a phone jack connector into an RJ-45 port. This will damage the switch. Use only  
twisted-pair cables with RJ-45 connectors that conform to FCC standards.  
Connecting to PCs, Servers, Hubs and Switches  
1. Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector.  
2. Attach the other end to an available port on the switch.  
3. Make sure each twisted pair cable does not exceed 100 meters (328 ft) in length.  
4. As each connection is made, the relevant Port LED (on the switch) corresponding to each port  
will light green or amber to indicate that the connection is valid.

Fiber Optic Devices  
Fiber Optic Devices  
An optional Gigabit SFP transceiver or 100BASE-FX SFP transceiver can be used for a backbone  
connection between switches, or for connecting to a high-speed server.  
Each single-mode fiber port requires 9/125 micron single-mode fiber optic cable with an LC  
connector at both ends. Each multimode fiber optic port requires 50/125 or 62.5/125 micron  
multimode fiber optic cabling with an LC connector at both ends.  
CAUTION  
This switch uses lasers to transmit signals over fiber optic cable. The lasers are compliant with  
the requirements of a Class 1 Laser Product and are inherently eye safe in normal operation.  
However, you should never look directly at a transmit port when it is powered on.  
NOTE  
When selecting a fiber SFP device, considering safety, please make sure that it can function at a  
temperature that is not less than the recommended maximum operational temperature of the  
product. You must also use an approved Laser Class 1 SFP transceiver.  
1. Remove and keep the LC port’s rubber cover. When not connected to a fiber cable, the rubber  
cover should be replaced to protect the optics.  
2. Check that the fiber terminators are clean. You can clean the cable plugs by wiping them gently  
with a clean tissue or cotton ball moistened with a little ethanol. Dirty fiber terminators on fiber  
cables will impair the quality of the light transmitted through the cable and lead to degraded  
performance on the port.  
3. Connect one end of the cable to the LC port on the switch and the other end to the LC port on  
the other device. Since LC connectors are keyed, the cable can be attached in only one  
orientation.  
FIGURE 21 MAKING CONNECTIONS TO SFP TRANSCEIVERS  
4. As a connection is made, check the Link LED on the switch corresponding to the port to be  
sure that the connection is valid.

configure the switch with a valid IP address, subnet mask, and default gateway. If you have trouble  
establishing a link to the management agent, check to see if you have a valid network connection.  
Then verify that you entered the correct IP address. Also, be sure the port through which you are  
connecting to the switch has not been disabled. If it has not been disabled, then check the network  
cabling that runs between your remote location and the switch.

Twisted-Pair Cable and Pin Assignments  
For 10/100BASE-TX connections, the twisted-pair cable must have two pairs of wires. For  
1000BASE-T connections the twisted-pair cable must have four pairs of wires. Each wire pair is  
identified by two different colors. For example, one wire might be green and the other, green with  
white stripes. Also, an RJ-45 connector must be attached to both ends of the cable.  
CAUTION  
DO NOT plug a phone jack connector into any RJ-45 port. Use only twisted-pair cables with RJ-45  
connectors that conform with FCC standards.  
CAUTION  
Caution: Each wire pair must be attached to the RJ-45 connectors in a specific orientation.  
The figure below illustrates how the pins on the RJ-45 connector are numbered. Be sure to hold the  
connectors in the same orientation when attaching the wires to the pins.  
FIGURE 22 RJ-45 CONNECTOR PIN NUMBERS

10BASE-T/100BASE-TX Pin Assignments  
Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections:  
100-ohm Category 3 or better cable for 10 Mbps connections, or 100-ohm Category 5 or better  
cable for 100 Mbps connections. Also be sure that the length of any twisted-pair connection does  
not exceed 100 meters (328 feet).  
The RJ-45 ports on the switch base unit support automatic MDI/MDI-X operation, so you can use  
straight-through cables for all network connections to PCs or servers, or to other switches or hubs.  
In straight-through cable, pins 1, 2, 3, and 6, at one end of the cable, are connected straight  
through to pins 1, 2, 3, and 6 at the other end of the cable. When using any RJ-45 port on this  
switch, you can use either straight-through or crossover cable.

1000BASE-T Pin Assignments  
All 1000BASE-T ports support automatic MDI/MDI-X operation, so you can use straight-through  
cables for all network connections to PCs or servers, or to other switches or hubs.  
The table below shows the 1000BASE-T MDI and MDI-X port pinouts. These ports require that all  
four pairs of wires be connected. Note that for 1000BASE-T operation, all four pairs of wires are  
used for both transmit and receive.  
Use 100-ohm Category 5, 5e or 6 unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable  
for 1000BASE-T connections. Also be sure that the length of any twisted-pair connection does not  
exceed 100 meters (328 feet).

Cable Testing for Existing Category 5 Cable  
Installed Category 5 cabling must pass tests for Attenuation, Near-End Crosstalk (NEXT), and  
Far-End Crosstalk (FEXT). This cable testing information is specified in the ANSI/TIA/EIA-TSB-67  
standard. Additionally, cables must also pass test parameters for Return Loss and Equal-Level  
Far-End Crosstalk (ELFEXT). These tests are specified in the ANSI/TIA/EIA-TSB-95 Bulletin, “The  
Additional Transmission Performance Guidelines for 100 Ohm 4-Pair Category 5 Cabling.”

Twisted-Pair Cable and Pin Assignments  
Note that when testing your cable installation, be sure to include all patch cables between switches  
and end devices.  
Adjusting Existing Category 5 Cabling to Run 1000BASE-T  
If your existing Category 5 installation does not meet one of the test parameters for 1000BASE-T,  
there are basically three measures that can be applied to try and correct the problem:  
1. Replace any Category 5 patch cables with high-performance Category 5e or Category 6 cables.  
2. Reduce the number of connectors used in the link.  
3. Reconnect some of the connectors in the link.

duplex mode) based on the capabilities of the node to which it is connected.  
Bandwidth  
The difference between the highest and lowest frequencies available for network signals. Also  
synonymous with wire speed, the actual speed of the data transmission along the cable.

Glossary  
Collision Domain  
Single CSMA/CD LAN segment.  
CSMA/CD  
CSMA/CD (Carrier Sense Multiple Access/Collision Detect) is the communication method employed  
by Ethernet, Fast Ethernet, and Gigabit Ethernet.  
End Station  
A workstation, server, or other device that does not forward traffic.  
Ethernet  
A network communication system developed and standardized by DEC, Intel, and Xerox, using  
baseband transmission, CSMA/CD access, logical bus topology, and coaxial cable. The successor  
IEEE 802.3 standard provides for integration into the OSI model and extends the physical layer and  
media with repeaters and implementations that operate on fiber, thin coax and twisted-pair cable.  
Fast Ethernet  
A 100 Mbps network communication system based on Ethernet and the CSMA/CD access method.  
Full Duplex  
Transmission method that allows two network devices to transmit and receive concurrently,  
effectively doubling the bandwidth of that link.  
Gigabit Ethernet  
A 1000 Mbps network communication system based on Ethernet and the CSMA/CD access  
method.  
IEEE  
Institute of Electrical and Electronic Engineers.  
IEEE 802.3  
Defines carrier sense multiple access with collision detection (CSMA/CD) access method and  
physical layer specifications.  
IEEE 802.3ab  
Defines CSMA/CD access method and physical layer specifications for 1000BASE-T Gigabit  
Ethernet. (Now incorporated in IEEE 802.3-2005.)  
IEEE 802.3u  
Defines CSMA/CD access method and physical layer specifications for 100BASE-TX Fast Ethernet.  
(Now incorporated in IEEE 802.3-2005.)  
IEEE 802.3x  
Defines Ethernet frame start/stop requests and timers used for flow control on full-duplex links.  
(Now incorporated in IEEE 802.3-2005.)

LAN Segment  
Separate LAN or collision domain.  
LED  
Light emitting diode used for monitoring a device or network condition.  
Local Area Network (LAN)  
A group of interconnected computer and support devices.  
Media Access Control (MAC)  
A portion of the networking protocol that governs access to the transmission medium, facilitating  
the exchange of data between network nodes.  
MIB  
An acronym for Management Information Base. It is a set of database objects that contains  
information about the device.  
Modal Bandwidth  
Bandwidth for multimode fiber is referred to as modal bandwidth because it varies with the modal  
field (or core diameter) of the fiber. Modal bandwidth is specified in units of MHz per km, which  
indicates the amount of bandwidth supported by the fiber for a one km distance.  
Network Diameter  
Wire distance between two end stations in the same collision domain.  
Redundant Power Supply (RPS)  
A backup power supply unit that automatically takes over in case the primary power supply should  
fail.  
RJ-45 Connector  
A connector for twisted-pair wiring.  
Switched Ports  
Ports that are on separate collision domains or LAN segments.  
TIA  
Telecommunications Industry Association  
Transmission Control Protocol/Internet Protocol (TCP/IP)  
Protocol suite that includes TCP as the primary transport protocol, and IP as the network layer  
protocol.

Glossary  
User Datagram Protocol (UDP)  
UDP provides a datagram mode for packet-switched communications. It uses IP as the underlying  
transport mechanism to provide access to IP-like services. UDP packets are delivered just like IP  
packets – connection-less datagrams that may be discarded before reaching their targets. UDP is  
useful when TCP would be too complex, too slow, or just unnecessary.  
UTP  
Unshielded twisted-pair cable.  
Virtual LAN (VLAN)  
A Virtual LAN is a collection of network nodes that share the same collision domain regardless of  
their physical location or connection point in the network. A VLAN serves as a logical workgroup  
with no physical barriers, allowing users to share information and resources as though located on  
the same LAN.
