POST and boot specifications

When the switch is turned on or rebooted, the switch performs POST. Total boot time with POST can be

several minutes. POST can be omitted after subsequent reboots by using the fastboot command or

entering the diagDisablePost command to persistently disable POST.

For more information about these commands, refer to the Fabric OS Command Reference.

POST

The success or failure results of the diagnostic tests that run during POST can be monitored through

LED activity, the error log, or the command line interface.

POST includes the following tasks:

1. Conducts preliminary POST diagnostics.

2. Initializes the operating system.

3. Initializes hardware.

4. Runs diagnostic tests on several functions, including circuitry, port functionality, memory, statistics

counters, and serialization.

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 assigns port addresses.

5. Constructs unicast routing tables.

6. Enables normal port operation.
