Boot

In addition to POST, boot includes the following steps after POST is complete:
1. Universal port configuration is performed.
2. Links are initialized.
3. Fabric is analyzed, and if any ports are connected to other switches, the switch participates in
4. Switch obtains a domain ID and assigns port addresses.
5. Unicast routing tables are constructed.
6. Normal port operation is enabled.

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.
To determine that POST completed successfully and whether or not any errors were detected:
1. Verify that the switch LEDs indicate that all components are healthy.
2. Verify that the switch prompt displays on the terminal of a computer workstation connected to
3. Review the switch system log for errors. Any errors detected during POST are written to the
For information about all referenced commands, and on accessing the error log, refer to the Fabric
OS Administrator's Guide. For information about error messages, refer to the Fabric OS Message
Reference Manual.

Maintaining the Brocade 300

The Brocade 300 does not require any regular physical maintenance; it was designed to minimize
the chance of failure.
Ensure that the environmental conditions, described in
are met. This helps prevent failure of the switch due to distress or abuse.

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.

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 through another management tool. If this
