System Administration 69
Sets or queries the state of the locator indicator (LED).
Without options, locator reports the current state of the LED on the
specified FRU.
If no target is specified, locator returns the current state of all locator LEDs.
A target argument is required when using the option fields:
on
Turns the LED on.
off
Turns the LED off.
The chassis locator is a white LED. If a FRU is specified, the FRU yellow
service LED is used along with the chassis (locator) LED.
Only one FRU can have a location indicator enabled at a time in an External
I/O Expansion Unit chassis. Turning off the chassis (locator) LED will also
turn off the blinking (service) FRU LED.
poweroff target
Powers down the given FRU and lights appropriate LEDs to indicate the FRU
is ready to remove. Must be used with the -f option. Be aware that using -f
can crash the domain.
Do not remove both power supply units (PSUs) in the same External I/O
Expansion Unit. If both PSUs are powered down in this way, then the
External I/O Expansion Unit cannot be turned back on from the command
line. It must be powered on physically.
Note – When a power supply is powered off, the LEDs and fan may still run
since they receive power from both supplies.
poweron target
Restores full power to an I/O boat or reenables output from the power
supply (PS) that has previously been marked ready-to-remove. When a PSU
is newly installed and the power switch is in the on position, or a boat is
connected to a powered link card, they automatically power themselves on.
However, this command can be used to power a PSU or I/O boat back on
that previously had been powered down for removal as long as the power
switch is in the on position.
