Fibre Channel port specifications

The Fibre Channel ports in the 8-Gb SAN Switch are compatible with SWL, LWL, and ELWL SFP
transceivers. The strength of the signal is determined by the type of transceiver in use.
The ports meet all required safety standards.
The ports are capable of operating at 1, 2, 4, or 8 Gb/s and are able to autonegotiate to the maximum
link speed.

POST and boot specifications

The switch performs POST by default each time it is powered on or rebooted or the system is reset.
Boot time with POST is usually about 1 to 3 minutes.
POST can be skipped after subsequent reboots by entering the fastBoot command. For more
information about this command, see the Fabric OS Command Reference Manual.

POST

The success/fail results of the diagnostic tests that run during POST can be monitored through LED
activity, the error log, or the CLI.
POST:
• Conducts preliminary POST diagnostics.
• Initializes the operating system.
• Initializes hardware.
• Runs diagnostic tests on several functions, including circuitry, port functionality, memory, statistics
counters, and serialization.
