Information Leds - IBM Brocade 4 Gb SAN Switch Module Installation Manual

The switch-module information panel contains the following components:
• LEDs that display the status of the switch module and its network connection. For more details
on LEDs, see "Information LEDs" on page 16.
• Six external Fibre Channel ports to connect Fibre Channel devices, such as disk subsystems,
tape drives, and other servers; and SAN devices, such as Fibre Channel switches, extenders, and
gateways. These connectors are identified as ports 0, 15, 16, 17, 18, and 19 in the I/O-module
configuration menus and are labeled 0, 15, 16, 17, 18, and 19 (from top to bottom) on the switch
module. The internal connectors are numbered 1 through 14.
Note: As shipped, 10 ports are enabled (three external, seven internal). To enable the remaining 10
ports for a full 20-port capacity, you must purchase two license keys. Each license key enables 5
ports.

Information LEDs

The front panel of the Fibre Channel switch module has multiple sets of LEDs. The first row of
LEDs at the top of the switch module represent the switch module status. The remaining sets of
LEDs represent status for the external Fibre Channel ports. The port LEDs include port speed, port
status, and port diagnostics.
The following illustration shows the locations of these LEDs on the switch module. A description of
each LED and corresponding activity follows the illustration.
Note:
• An amber LED is lit when a system error or event has occurred. To identify the error or
event, check the other LEDs on the information panel of the switch module.
• An LED test occurs whenever the switch module is powered on. All LEDs are lit and remain
lit for approximately 5 seconds during POST and then all the LEDs except the Power LED
will turn off. The Power LED flashes to indicate a normal POST condition; then, POST
proceeds as described in step 11 on page 12.
