System LEDs

Troubleshooting the Hardware 3-3

CPU-I/O Enclosure Status LEDs

Each CPU- I ⁄ O enclosure contains three LEDs that describe the status of the

components in the enclosure, including the CPU, BMC, VTM, PCI adapters, and SATA

disk drives. These LEDs, which are located on the front and rear of each enclosure, are

green, amber, and white. The CPU- I ⁄ O enclosure status LEDs are shown in

Figure 3-1 and described in Ta ble 3 - 2.

NOTE

During the boot process, the BMC verifies that all devices

in the CPU- I ⁄ O enclosures are present and performing

normally before the BMC activates that enclosure. If a

component has failed, the BMC removes power from that

enclosure. As a result, the LEDs on an enclosure might

turn on briefly and then turn off, or the LEDs might not turn

on at all, indicating a failed component of the enclosure.
