Chapter 1 Overview
f Power supply unit status LED (on the redundant power supply only)
This LED is on, depending on the power supply unit status as follows.
g System status LED / System identification LED
This LED lights or blinks in amber when an error is detected in the server components. If this
LED lights or blinks, refer to "Contact Information" in "Start Guide", and contact your
maintenance engineer or device administrator.
This LED is lit when the server is in standby mode (when the AC power is on and the DC power
is off), but this does not indicate an error.
When pressing the system identification LED button located on the front of the server, the front
and rear LEDs are lit blue so that the locations of devices being maintained can be determined.
Also, the [System Identification LED Display] button of ServerView can be used to light them.
