IBM P 615 series User Manual

If the system is running Linux, you can determine the FRU part numbers of the electronic assemblies in a
partition by using the lscfg -vp | more command. This command displays the detailed VPD of the
electronic assemblies in the system.
FRU Identify LEDs
This system is configured with an arrangement of LEDs that help identify various components of the
system. These include but are not limited to:
v Rack identify LED
v CEC drawer identify LED
v I/O drawer identify LED
v RIO port identify LED (Not Used)
v FRU identify LED
– Power subsystem FRUs
– CEC subsystem FRUs
– I/O subsystem FRUs
v I/O adapter identify LED
v DASD identify LED.
The identify LEDs are arranged hierarchically with the FRU identify LED at the bottom of the hierarchy,
followed by the corresponding CEC or I/O drawer identify LED, and the corresponding rack identify LED to
locate the failing FRU more easily.
Any identify LED in the system may be flashed when the system is in the failed state with power on by
using the service processor ″LED Control Menu″ contained in the “System Information Menu” on page
238.
Any identify LED in the system may also be flashed by using the ″Identify and Attention Indicators″ task in
diagnostics. The procedure to operate the ″Identify and Attention Indicators″ task in diagnostics is outlined
in Chapter 27 of the RS/6000 Eserver pSeries Diagnostic Information for Multiple Bus Systems.
If the service processor menus and the AIX diagnostics are not available, the FRU identify LEDs may be
flashed by one of following:
1. If the system is configured as a full system partition, the system can be booted to the open firmware
prompt and the FRU-LED-MENU command entered. A menu displays that will allow you to turn on the
desired FRU identify LED. For instructions on setting the boot mode to enable the boot to the open
firmware prompt, see “System Power Control Menu” on page 235.
2. If an HMC is attached, it may be used to activate and deactivate a FRU identify LED. For instructions
on activating and deactivating a FRU identify LED, see the Service Focal Point chapter of the IBM
Hardware Management Console for pSeries Installation and Operations Guide, order number
SA38-0590.
