Locator Switch/Led (Unit Identifier Or Uid); Diagnostics Panel Leds - HP Integrity rx6600 User's & Service Manual

This LED indicates the overall health state of the system, including the state of system firmware and
the OS. If the LED is Amber or Red, the system needs attention, and the event logs should be
examined for details of the problem.

Locator Switch/LED (Unit Identifier or UID)

The Locator Switch/LED allows a specific system to be identified in a rack or data center
environment. One Locator Switch/LED is located in the front panel, and a second is located in the
rear of the chassis. LEDs are incorporated inside the pushbutton to minimize space. Both switches
are toggle switches, meaning you push it once to turn on the LED, and you push it again to turn
off the LED. Pressing the front panel Switch/LED, or entering the iLO 2 MP and LOC commands,
lights the rear panel LED, and vice versa.
Off = Off
Blue (Not flashing) = Identification

Diagnostics Panel LEDs

The Diagnostics Panel improves serviceability by allowing you to look in a single location for the
LEDs that provide failing FRU locating/mapping information. These amber LEDs are only lit when
a failure occurs; otherwise, they are off. A label on the panel is oriented in a fashion analogous
to the orientation of the components within the server: a diagnostic LED exists for each FRU in the
system, including all DIMMs.
