Table 7-1 lists the meanings for the various attention indicator states.
When all of a system’s components are functioning, and no service
operations are occurring, every attention indicator should be turned off.
(HP Superdome cabinet number LCDs remain lit or blinking when
cabinet power is on.)
You can control (turn off, blink, and/or turn on) attention indicators for
the following hardware components:
• Cells—Each cell or cell slot has its own attention indicators.
—OnHPSuperdome servers, each cell’s attention indicator is located
on the server cabinet hardware below the cell’s slot, just to the
right of the cell slot’s power LED.
— On HP rp8400 servers, each cell’s attention indicator is located on
the cell hardware, to the outside of the cell’s power LEDs.
• I/O Chassis—On HP Superdome servers only, each I/O chassis has a
attention indicator, which is located on the cabinet above the I/O
chassis.
• PCI Card Slots—On all HP nPartition systems, each PCI card slot
has an attention indicator that you can use to select the card slot. You
can view a PCI card slot’s attention indicator when accessing the card
cage.
On HP 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.
