5. Names and Functions of Components
Chapter 1 General Description

Location LED
The failed FRU can be identified in detail by viewing Location LED together with FRU LED. (For FRU LED, see
Chapter 1 (1.6.5 FRU (CPU, MEM, PCI, PSU/FAN, NEXT, MISC) LED).) Location LED is composed of 8 LEDs.
If any of 8 LEDs are lit, the relevant FRU LED (one of CPU, MEM, PCI, PSU/FAN, MISC) also goes on at the
same time.
The following table lists Location LED patterns and their explanation.
