System pulse LEDs
The following LEDs are on the system board and monitor the system power-on
and power-off sequencing and boot progress: (see “System-board LEDs” on page
33 for the location of these LEDs)
LED Description Action
RTMM
heartbeat Power-on and
power-off sequencing.
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.
IMM2
heartbeat IMM2 heartbeat boot
process. 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.
Server power features
When the server is connected to an ac power source but is not turned on, the
operating system does not run, and all core logic except for the service processor
(the Integrated Management Module II) is shut down; however, the server can
respond to requests to the service processor, such as a remote request to turn on
the server. The power-on LED flashes to indicate that the server is connected to ac
power but is not turned on.
Turning on the server
Approximately 5 seconds after the server is connected to ac power, one or more
fans might start running to provide cooling while the server is connected to power
and the power-on button LED will blink quickly. Approximately 1 to 3 minutes
after the server is connected to ac power, the power-control button becomes active
(the power-on LED will blink slowly), and one or more fans might start running to
provide cooling while the server is connected to power. You can turn on the server
by pressing the power-control button.
The server can also be turned on in any of the following ways:
v
If a power failure occurs while the server is turned on, the server will restart
automatically when power is restored.
v If your operating system supports the Wake on LAN feature, the Wake on LAN
feature can turn on the server.
Note:
1. When 4 GB or more of memory (physical or logical) is installed, some memory
is reserved for various system resources and is unavailable to the operating
system. The amount of memory that is reserved for system resources depends
on the operating system, the configuration of the server, and the configured
PCI options.
