Front Panel LEDs

The front panel of the server blade contains the unit identifier (UID) LED, system power LED, health LED,

and the network interface controller (NIC) LEDs. Figure 5-1 shows the front panel LED locations.

Server blades use flashing states (amber or red) on these LEDs to indicate a warning or an error.

There are a total of seven buttons, arranged vertically (when the server blade is installed in the enclosure).

In addition to the two integrated button/LEDs, there is one health LED.

The health LED is arranged sequentially in line with the Power button/LED, and as the server blade starts

up, there will be more “green” the further the system proceeds in the startup process:

1. The power LED turns green soon as the system starts to power up.

2. The health LED turns green when firmware leaves “exit boot services” and starts the OS boot.

The health LED is driven by the BMC; the Power LED is driven solely by hardware. Both BMC and MP code

determine the state of the health LED.
