Interpreting POST results

5. Constructs unicast routing tables.

6. Enables normal port operation.

Interpreting POST results

POST is a system check that is performed each time the switch is powered on, rebooted, or reset.

During POST, the LEDs flash either amber or green. Any errors that occur during POST are listed in

the error log.

Complete the following steps to determine whether POST completed successfully and whether any

errors were detected.

1. Verify that the switch LEDs indicate that all components are healthy.

See Table 1 and Table 2 for descriptions and interpretations of LED patterns. If one or more

LEDs do not display a healthy state, verify that the LEDs on the switch are not set to “beacon”

by entering the switchShow command to detect if beaconing is active.

2. Verify that the switch prompt displays on the terminal of a computer workstation connected to

the switch.

If there is no switch prompt when POST completes, press Enter. If the switch prompt still does

not display, try opening a Telnet session or accessing the switch through another management

tool. If this is not successful, the switch did not successfully complete POST. Contact your

switch supplier for repair.

3. Review the switch system log for errors. Any errors detected during POST are written to the

system log, accessible through the errShow command.

For information about all referenced commands, and on accessing the error log, refer to Fabric OS

Administrator’s Guide. For information about error messages, refer to the Fabric OS Message

Reference Manual.

Brocade 5300 Maintenance

The Brocade 5300 is designed for high availability and low failure; it does not require any regular

physical maintenance. It includes diagnostic tests and field-replaceable units, described in the

following sections.

Installing an SFP

The Brocade 5300 only supports Brocade-branded SFPs. If you use an unqualified SFP, the

switchShow command output shows the port in a Mod_Inv state. Fabric OS also logs the issue in

the system error log.

Complete the following steps to install an SFP.

1. Making sure that the bail (wire handle) is in the unlocked position, place the SFP in the

correctly oriented position on the port, as shown in Figure 5.

2. Slide the SFP into the port until you feel it click into place; then close the bail.
