Hi,
I have a broken switch here to play around with and I am wondering if you can help me revive it.
It is an SN2700 and it has the following symptoms:
- Nothing on serial - not even BIOS POST.
Outside LEDS:
- System Status LED: constant red
- Fan Status LED: off
- Power Suply LEDs: constant red
- Bad port led: off
- UID led: off
- All switch ports: constant orange
Port side board:
- 3.3V AUX, 12V, 3.3v_SEN, VCORE, 1.2V, 1.8V: Constant green
- D18: constant green
- D19, D20, D17: off
Main CPLD Leds: L0,1,3,4,5,6,7: off. L2: constant green
Main board:
- D9 (0.85v VCCA): off
- D10 (1.05_VCCP: off
- D11 (1.05_LAN): constant green
- D12 (5v): constant green
- D13 (3.3v): constant green
- D14 (1.35v): off
I think the problem lies with these last few leds which I beleve are indicating that the CPU and memory voltages are not working or are not active.
If I remove the DIMM the result is the same. I’ve already tried replacing the DIMM but that makes no difference it seems.
I would appreciate any suggestions, I am hoping to use this one for testing in the lab here. Thanks!
