The following steps describe the different
stages of the IMM heartbeat sequencing process.
- When this LED is blinking fast (approximately 4Hz), this indicates,
that the IMM code is in the loading process.
- When this LED goes off momentarily, this indicates that the IMM
code has loaded completely.
- When this LED goes off momentarily and then starts blinking slowing
(approximately 1Hz), this indicates that IMM is fully operational.
You can now press the power-control button to power-on the server.

source to the server, complete the following steps:
- (Trained service technician only) use the IMM recovery jumper
to recover the firmware (see System-board switches and jumpers).
