Greetings!
-> What is the LED indication on the server front panel when this issue occurs? Please refer below web-link:
-> If the issue is intermittent, please try updating the system ROM and check for the issue.
-> If the server is down and not booting to OS, please clear NVRAM and check.
Steps to clear NVRAM
1. Shut down the server and disconnect all the power supplies.
2. Move the switchS1,S5 and S6 (of system maintenance switch) to the other side.
3. Power on the server and check for the message that the NVRAM has been cleared
4. Shut down the server and move S1,S5 and S6 S6 to the original position.
5. Power on the server.
- Safety notes: Please take all ESD (Electro-Static Discharge) safety precautions when performing any internal intervention on your server. When the server boots after NVRAM is cleared, a delay of up to 2 minutes is normal. During this delay, the system appears non-functional. Do not attempt any procedures during the delay.
Please refer page#87 and 88 on the web-link below to locate the system maintenance switch on the system board.
