Understanding POST Results
Table 3-1 lists the ten POST tests and their associated LEDs.
POST tests run automatically each time the switch is powered on. When the switch begins POST, the port LEDs turn green. The System LED flashes green, and the RPS LED turns off. As each test runs, the port LEDs, starting with number 1, turn off. The remaining port LEDs each turn off in sequence as the system completes a test.
When POST completes successfully, the port LEDs return to the status mode display, showing that the switch is operational. If a test fails, the port LED associated with the test turns amber, and the system LED turns amber.
--> Note POST failures are usually fatal. Call Cisco Systems if your switch does not pass POST.
Table 3-1: POST Test Descriptions
Switch LED Component Tested
LED 1
DRAM
LED 2
Flash memory
LED 3
CPU interface buffer
LED 4
CPU interface ASIC
LED 5
Switch core ASIC
LED 6
TCAM
LED 7
Ethernet controller ASIC
LED 8
Ethernet interfaces
LED 9
CPU interface buffer second stage
LED 101
Inline Power Controller Test
If your 3550 boots the IOS and work properly, you shuld try upgrade your bootloader.
Hope this helps.
