Listing and Managing Server Hardware
Turning Attention Indicators (LEDs) On and Off
HP System Partitions Guide: Administration for nPartitions, rev 5.1 327
On HP rp7410 and rp8400 servers only, you also can view each PCI
slot’s attention indicator beneath the corresponding slot, on the
cabinet’s external chassis at the rear of the server cabinet.
• Cabinet Number LCDs
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, HP rp8400, and HP
rp7410 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.
Turning Attention LEDs On and Off [HP-UX]
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. Login 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 nPartition. To manage PCI slot attention indicators, you
must access HP-UX in the local nPartition 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.
