Description
Power-on and power-off
sequencing.
IMM2 heartbeat boot process.
Action
1. If the LED blinks at 1Hz, it is functioning
properly and no action is necessary.
2. If the LED is not blinking, (trained
technician only) replace the system board.
The following steps describe the different
stages of the IMM2 heartbeat sequencing
process.
1. When this LED is blinking fast
(approximately 4Hz), this indicates, that the
IMM2 code is in the loading process.
2. When this LED goes off momentarily, this
indicates that the IMM2 code has loaded
completely.
3. When this LED goes off momentarily and
then starts blinking slowing (approximately
1Hz), this indicates that IMM2 is fully
operational. You can now press the power-
control button to power-on the server.
4. If this LED does not blink within 30 seconds
of connecting a power source to the server,
(trained technician only) replace the system
board.
