• Cabinet Number—On HP Superdome servers only, each cabinet has
a cabinet number LCD that serves as the cabinet’s attention
indicator.
NOTE The cabinet “attention” light on HP Superdome and HP rp8400
servers is not user-controllable.
The cabinet “attention” light automatically turns on when one or more
alert level 6 (or higher) chassis codes has been recorded in the error logs
and has not yet been read. This light automatically turns off when a user
enters the service processor (GSP or MP) chassis logs viewer.
HP-UX Commands This procedure (fruled -o..., fruled -f..., or rad -f...) manages
attention indicators by turning them on, off, or blinking them from
HP-UX.
Step 1. Log in to HP-UX running on one of the system’s nPartitions.
You can manage cabinet, cell, and I/O chassis attention indicators from
HP-UX on any partition. To manage PCI slot attention indicators, you
must access HP-UX in the local partition to which the PCI slot’s chassis
is assigned.
Step 2. Use the fruled command or the rad command to manage (turn on, off,
or blink) the attention indicator for a system hardware component.
From HP-UX you can manage LEDs for the following hardware
components:
• Cells—Use fruled to blink or turn off a cell’s attention indicator.
— Turn Off: The fruled -f -c # command turns off the attention
indicator for the specified cell (-c # ). To turn off all cell attention
indicators use the fruled -f -C command.
— Blink: The fruled -o -c # command blinks the attention indicator
for the specified cell (-c # ).
• I/O Chassis—Use fruled to blink or turn off HP Superdome I/O
chassis attention indicators.
Specify the I/O chassis using cabinet/bay/chassis notation ( #/#/# ).
