Phase 0 Power On Diagnostic Tests
At power on, the Status LEDs cycle through diagnostic test patterns as
internal SwitchMaster™ Bridge software tests: Flash, serial port, dynamic
RAM, static RAM, dual port memory, and each of the Ethernet ports.
During each of the diagnostic tests, the four Bridge Status LEDs at the top
of the Status LEDs cycle in a steady right to left pattern to indicate test
progress. The pattern of the four LEDs at the bottom of the Status LEDs
indicates the hardware being tested.
