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.

Description of Hardware

The Brocade 6910 switches consist of two model types, one hardened for extended temperature
range environments, the other non-hardened for standard temperature range environments:

• Standard temperature range switches for 0 to +55 °C:

• BR-6910-EA-AC

• BR-6910-EA-DC

• Extended temperature range switches for -40 to +65 °C:

• BR-6910-EA-H-AC

• 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 +55 °C.

The SFP slots support the following SFP transceivers:

• Standard temperature range optics (0 to +55 °C)

• 100Base-FX-IR

• 100Base-FX-LR

• 1000Base-SX (OM) 33210-100

• 1000Base-LX (OM) 33211-100

• 1000Base-LHA (OM) 33212-100

• 1000Base-LHB 33004-000

• 1000Base-BXU 33006-000

• 1000Base-BXD 33005-000

• 1000Base-CWDM

• Extended temperature range optics (-40 to +65 °C)

• 1000Base-SX (OM)

• 1000Base-LX (OM)

• 1000Base-LHA (OM)

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

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.

“1000BASE-T Pin Assignments” on page 29.)

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
used to connect to the alarm port.

4. If installing multiple switches, attach four adhesive feet to each one. Place each device
squarely on top of the one below, in any order.

Rack Mounting

Before rack mounting the switch, pay particular attention to the following factors:

• Temperature: Since the temperature within a rack assembly may be higher than the ambient

room temperature, check that the rack-environment temperature is within the specified
operating temperature range. Also be sure to leave adequate space around the ventilation
holes in the switch.

• Mechanical Loading: Do not place any equipment on top of a rack-mounted unit.

• Circuit Overloading: Be sure that the supply circuit to the rack assembly is not overloaded.

• Grounding: Rack-mounted equipment should be properly grounded. Particular attention should

be given to supply connections other than direct connections to the mains.

NOTE

NOTE

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

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.

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.

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.

4. The switch chassis is connected internaly to 0 V. This circuit is connected to the grounding
terminal on the front of the switch. The surface area around this terminal is not painted in
order to provide for a good connection. Attach a 18 AWG stranded copper wire to the grounding
terminal on the switch.

5. Then attach the grounding wire to the ground point on the rack.

1. Attach an insulated grounding wire, with a metal screw, to the marked grounding point.

2. Terminate the wire in an earthed grounding point.

The earth connection must not be removed unless all supply connections have been
disconnected.

Connecting to a Power Source

These switches support either AC or DC only dual power supplies.

Before wiring the DC plug or connecting power to the switch, ensure that power to the feed lines
is turned off at the supply circuit breaker or disconnected from the power bus

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.

Remove both power cords before servicing.

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.)

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.

14 Brocade 6910 Ethernet Access Switch Hardware Installation Guide

53-1002650-02

Connecting to a Power Source

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 15. 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.

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

3

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
information on cabling.

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.

“Twisted-Pair Cable and Pin Assignments” on page 27 for further

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

CAUTION

NOTE

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.

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.

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.

In-Band Access

You can access the management agent in the switch from anywhere within the attached network
using Telnet, a Web browser, or other network management software tools. However, you must first
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.

Cables

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.

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: Each wire pair must be attached to the RJ-45 connectors in a specific orientation.

B

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.

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.”

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.

devices near the input power connectors.

MISE EN GARDE Assurez-vous que le dispositif ne risque pas de surcharger les circuits d'alimentation, le

câblage et la protection de surintensité. Pour déterminer le risque de surcharge des
circuits d'alimentation, additionnez l'intensité nominale (ampères) de tous les dispositifs
installés sur le même circuit que le dispositif en question. Comparez alors ce total avec la
limite de charge du circuit. L'intensité nominale maximum en ampères est généralement
imprimée sur chaque dispositif près des connecteurs d'entrée d'alimentation.

CAUTION Make sure the air flow around the front, sides, and back of the device is not restricted.

MISE EN GARDE Vérifiez que rien ne restreint la circulation d'air devant, derrière et sur les côtés du

dispositif et qu'elle peut se faire librement.

CAUTION Use a separate branch circuit for each AC power cord, which provides redundancy in case

one of the circuits fails.

MISE EN GARDE Utilisez un circuit de dérivation différent pour chaque cordon d’alimentation C.A. Ainsi, il y

aura un circuit redondant en cas de panne d’un des circuits.

VORSICHT Montage (Rack Mounting Instructions - German)

Switch-Einheiten können an ein standardmäßiges 19-Zoll Einrichtungsrack, einen
Arbeitstisch oder ein Regal montiert werden. Folgend finden Sie die
Montageanweisungen für jeden Positionstyp.

Rack-Montage
Beachten Sie die folgenden Faktoren, bevor Sie die Rack-Montage beginnen:

• Temperatur: Da die Temperatur innerhalb einer Rackeinheit höher als die

Raumumgebungstemperatur sein kann, stellen Sie bitte sicher, dass die
Rackumgebungstemperatur innerhalb des angegebenen
Betriebstemperaturbereichs liegt.

• Mechanische Last: Stellen Sie kein Gerät auf eine Rack-Montageeinheit.

• Stromüberlastung: Stellen Sie sicher, dass der Netzkreis der Rackeinheit nicht

überlastet wird.

• Erdung: Die Rack-Montageeinheit muss richtig geerdet werden. Besondere Acht

sollten Sie bei Verbindungen geben, die nicht direkt zum Netz führen.
So montieren Sie Geräte an ein Rack:
1 Befestigen Sie die Metallwinkel mit den im Metallwinkel-Montageset erhältlichen

Schrauben an dem Gerät.
2 Befestigen Sie das Gerät mit vier Rackmontageschrauben (nicht beigelegt) an dem

Rack.
3 Wenn Sie nur einen Switch installieren, dann springen Sie bitte über zu "Verbinden

mit einer Stromquelle".
4 Wenn Sie mehrere Switches installieren möchten, dann montieren Sie sie

untereinander in einer beliebigen Reihenfolge.
