You can power on or power off server cabinets by using
any one of the following procedures: When powering off a cabinet, you turn off 48-volt power
to the cabinet thus causing all cells and all I/O chassis to power off, and
causing most fans to turn off. Changes in cabinet power status do not affect the standby
power that supplies system utilities such as the service processor (GSP or
MP) and keeps some fans running. These utilities and fans can receive power
as long as standby power is enabled. Procedure 7-1 Powering Server Cabinets On and Off (Cabinet Power Switch) Use the Virtual Front Panel to check status, and then use
the cabinet power switch to manage 48-volt power for a cabinet with the cabinet
hardware. Login to the
service processor for the server complex and access the Virtual Front Panel
for the system. From the service processor Main
menu, enter VFP to access the Virtual Front Panel menu,
then enter S to access the "system VFP" that displays
the current status for all nPartitions. Check the VFP
status to see whether any cabinet hardware is running an operating system
(OS). Any nPartition whose state is "OS heartbeat"
is running an OS and thus should not have its hardware powered off until after
the OS is shut down. Type ^b (Control-b)
to exit the VFP. Shut down the
OS running on any cabinet hardware that you plan to power off. Confirm that
nobody else is using or servicing the cabinet hardware you plan to power on
or off. Both physically inspect the hardware and
check whether others are remotely accessing the service processor (using the WHO command
at the Command menu). Access the cabinet
hardware and flip the power switch (located on the front of the cabinet) to
the on or off position in order to power the cabinet on or off.
Procedure 7-2 Powering Server Cabinets On and Off (Service Processor) Use the Virtual Front Panel, and then use the Command menu PE command
to turn 48-volt cabinet power on or off from the service processor (GSP or
MP). Login to the
service processor for the server and access the Virtual Front Panel for the
system. From the service processor Main menu, enter VFP to
access the Virtual Front Panel menu, then enter S to
access the "system VFP" that displays the current status for all nPartitions. Check the VFP
status to see whether any cabinet hardware is running an operating system
(OS). Any nPartition whose state is "OS heartbeat"
is running an OS and thus should not have its hardware powered off until after
the OS is shut down. Type ^b (Control-b)
to exit the VFP. Shut down the
OS running on any cabinet hardware that you plan to power off. Confirm that
nobody else is using or servicing the cabinet hardware you plan to power on
or off. Both physically inspect the hardware and
check whether others are remotely accessing the service processor (using the WHO command
at the Command menu). Access the service
processor Command menu, issue the PE command, then
select the cabinet to power on or power off. From
the service processor Main menu, enter CM to access
the Command menu. To exit the Command menu enter MA. When using the PE command enter B to
power on or off a cabinet; specify the cabinet number; and then enter ON (power
on), OFF (power off), or Q (quit
without changing the power status). GSP:CM> PE
This command controls power enable to a hardware device.
B - Cabinet
C - Cell
I - IO Chassis
Select Device: b
Enter cabinet number: 1
The power state is ON for Cabinet 1.
