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.

The switches have a 1000BASE-T port for dedicated management access (which can be operated
outside the data channel). It has an SNMP-based management agent embedded on the main
board, which supports both in-band and out-of-band access using a Web browser, SNMP/RMON, or
Teln et.

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.

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.

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.

Selecting a Site

Switch units can be mounted in a standard 19-inch equipment rack or on a flat surface. Be sure to
follow the guidelines below when choosing a location.

• The site should:

• be at the center of all the devices you want to link and near a power outlet.

• be able to maintain its temperature within -40 to 65 °C (-40 to 149°F) and its humidity

within 10% to 90%, non-condensing

• provide adequate space (approximately two inches) on all sides for proper air flow

• be accessible for installing, cabling and maintaining the devices

• allow the status LEDs to be clearly visible

• Make sure twisted-pair cable is always routed away from power lines, fluorescent lighting

fixtures and other sources of electrical interference, such as radios and transmitters.

• Make sure that the unit is connected to a separate grounded power outlet that provides 100 to

240 VAC, 50 to 60 Hz, is within 2 m (6.6 feet) of each device and is powered from an
independent circuit breaker. As with any equipment, using a filter or surge suppressor is
recommended.

Ethernet Cabling

To ensure proper operation when installing the switch into a network, make sure that the current
cables are suitable for 10BASE-T, 100BASE-TX or 1000BASE-T operation. Check the following
criteria against the current installation of your network:

• Cable type: Unshielded twisted pair (UTP) or shielded twisted pair (STP) cables with RJ-45

connectors; Category 3 or better for 10BASE-T, Category 5 or better for 100BASE-TX, and
Category 5, 5e or 6 for 1000BASE-T.

• Protection from radio frequency interference emissions

• Electrical surge suppression

• Separation of electrical wires (switch related or other) and electromagnetic fields from data

based network wiring

• Safe connections with no damaged cables, connectors or shields
