2. Use the fruled command and either the rad command (HP-UX B.11.11) or the olrad
command (HP-UX B.11.23 and HP-UX B.11.31) to manage (turn on, off, or blink) the attention
indicator for a system hardware component.
From the command line you can manage LEDs for the following hardware components:
• Cells—Use fruled to blink or turn off a cell 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 (#/#/#).
— Turn Off: The fruled -f -i#/#/# command turns off the attention indicator for
the specified I/O chassis (-i#/#/#). To turn off all I/O chassis attention indicators
use the fruled -f -I command.
— Blink: The fruled -o -i#/#/# command blinks the attention indicator for the
specified I/O chassis (-i#/#/#).
• Cabinet Numbers—Use fruled to blink or not-blink (keep lit) the cabinet number LCD
for an HP Superdome cabinet.
— Not-Blink: The fruled -f -b# command stops blinking (keeps it lit) the cabinet
number LCD for the specified cabinet (-b#).
— Blink: The fruled -o -b# command blinks the cabinet number LCD for the
specified cabinet (-b#).
• PCI Card Slots—Managing the attention indicator for a PCI card slot is supported from
HP-UX only.
Use the rad command (HP-UX B.11.11 only) or olrad command (HP-UX B.11.23 and
HP-UX B.11.31) to turn on, off, or blink the attention indicator for a PCI card slot.
Specify the PCI slot using cabinet-bay-chassis-slot (#-#-#-#) notation.
— Turn Off PCI Card Slot Attention Indicator
The HP-UX B.11.11 rad -f off slot command turns off the attention indicator
for the specified PCI card slot (slot).
The HP-UX B.11.23 and HP-UX B.11.31 olrad -I OFF slot command turns off
the attention indicator for the specified PCI card slot (slot).
— Blink PCI Card Slot Attention Indicator
The HP-UX B.11.11 rad -f attention slot command blinks the attention
indicator for the specified PCI card slot (slot).
The HP-UX B.11.23 and HP-UX B.11.31 olrad -f ATTN slot command blinks
the attention indicator for the specified PCI card slot (slot).
— Turn On PCI Card Slot Attention Indicator
The HP-UX B.11.11 rad -f on slot command turns on the attention indicator
for the specified PCI card slot (slot).
The HP-UX B.11.23 and HP-UX B.11.31 olrad command does not support turning
