POST and boot specifications
The Brocade 7800 runs POST by default each time it is powered on; it typically requires from 1 to 3
minutes to boot and complete POST.
POST can be skipped after subsequent reboots by entering the fastBoot command. For more
information about this command, see the Fabric OS Command Reference.
POST
The success/fail results of the diagnostic tests that run during POST can be monitored through LED
activity, the error log, or a command line interface.
POST includes the following tasks:
1. Conduct preliminary POST diagnostics
2. Initialize the operating system
3. Initialize hardware
4. Run 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. Perform universal port configuration
2. Initialize links
3. Analyze fabric. If any ports are connected to other Extension Switches, the Extension Switch
participates in a fabric configuration
4. Obtain a domain ID and assigning port addresses
5. Construct unicast routing tables
6. Enable normal port operation
