Interpreting POST results

Boot

In addition to POST, boot includes the following tasks after POST is complete:
1. Performs universal port configuration.
2. Initializes links.
3. Analyzes fabric. If any ports are connected to other switches, the switch participates in a fabric configuration.
4. Obtains a domain ID and assigning port addresses.
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 the LED patterns section 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 the following figure.
