Resetting or Inhibiting Processor Modules and Power Supplies
The RESET CHASSIS POWER SUPPLY HOLD command is equivalent to turning off the
power supply. Doing this shuts off the power supply until you issue a RESET CHASSIS
POWER SUPPLY command. You can only inhibit a redundant power supply. If you
specify a required power supply, the command resets the processor on the power supply, but
does not inhibit it.
Note: The SHOW [SERVER] POWER SUPPLY STATUS COMMAND and the SHOW
[SERVER] CHASSIS SUMMARY command indicate whether a managed power
supply is Required, Redundant, or Disabled.
The RESET CHASSIS POWER SUPPLY command behaves differently, depending on
whether the power supply you specify is in use or inhibited. If the power supply is in use, this
command resets the SCM on the power supply and does not interrupt power. No physical
equivalent of this command exists on power supply itself. This type of reset is available
from the command interface of a processor module only.
If you enter the RESET CHASSIS POWER SUPPLY command and specify a power supply
that is inhibited through a RESET CHASSIS POWER SUPPLY HOLD command, the reset
activates the power supply as well as resetting the SCM. In this case, the command is
equivalent to turning on the power supply. (If a user has turned off the power supply, you
cannot turn it on with this command. You must physically turn on the power supply.)
The status of a power supply indicates whether it is Required, Redundant, or Inhibited.
Before you reset or hold a power supply, you can check the status with either the
SHOW/MONITOR CHASSIS SUMMARY display or the SHOW/MONITOR CHASSIS
POWER SUPPLY STATUS command. The Chassis Summary display gives a one line
status of each managed power supply, and the Power Supply Status display gives detailed
status for each power supply. Figure 6-1 is a Chassis Summary display. Figure 6-2 is a
Power Supply Status display.
