22 Brocade SAN Switch Module: Installation Guide
The switch-module information panel contains the following components:
• Comprehensive LEDs that display the status of the switch module and the network. For
more information, see “LEDs.”
• Two external Fibre Channel connectors 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 port 0 and port
15 in the switch configuration menus and are labeled 0 and 15 (from top to bottom) on
the switch module, as shown in Figure 8.
✏ NOTE
The internal connectors are numbered 1 through 14.
LEDs
After you install the switch module in the SBCE unit, the switch-module LEDs become
active. There are three possible LED states: off, lit, and flashing. The lit (steady) LEDs and
flashing LEDs can be green or amber.
The LEDs might display any of these states and colors during startup, POST, or other
diagnostic tests. This is typical and does not indicate a problem, unless the LEDs do not
indicate a healthy state after all the startup (boot) processes and diagnostic tests have been
completed. If one or more LEDs do not display a healthy state, make sure that the LEDs are
not set to beacon. For information about how to turn beaconing on and off, see the Brocade
Fabric OS Procedures Guide or the Brocade Advanced Web Tools Administrator’s Guide
v4.2.0 or later on the Resource CD.
Any errors that are detected during POST are written to the system log. This log is
accessible through the errShow command. For information about this command, see the
Brocade Fabric OS Procedures Guide on the Resource CD. For information about error
messages, see the Brocade Diagnostic and System Error Message Reference Manual on the
Resource CD.
✏ NOTE
You can also use the management module to make sure that the switch module is
correctly operating. For more information, see the
Intel Server Chassis SBCE
Installation and User’s Guide and the Intel Server Chassis SBCE Hardware
Maintenance Manual and Troubleshooting Guide on the Resource CD.
Figure 9 shows the locations of the LEDs on the switch module. To interpret the meaning of
the LED states, see Table 2.
