position (pin 2 and pin 3).
7. Wait more than 10 seconds and then move the Clear CMOS jumper back to the normal position (pin 1

8. Reinstall any parts and reconnect any cables. Then, reinstall the server cover. See "Completing the

TMM Enable/Disable jumper (also known as BMC Enable/Disable jumper)
When the TMM Enable/Disable jumper is in the default normal position (pin 1 and pin 2), the server needs
about 30 seconds for the TMM to initialize whenever you connect the server to an ac power source. If you
press the power switch on the front of the chassis during this period, the server will not start immediately; it
will start after the TMM initialization finishes.
If you move the TMM Enable/Disable jumper to pin 2 and pin 3, the TMM function is not available and the
server will be directly turned on when you press the power switch without waiting for the TMM to be ready.
