32 QXS G2 Hardware Installation and Maintenance Guide
System Power On/Standby LED (green/amber)
LED displays amber when only standby power is available. LED displays green when system power is
available.
Module Fault LED (amber)
LED illuminates when experiencing a system hardware fault. It may be associated with a Fault LED on
a PSU, RAID controller, or expansion IOM that helps the user to identify which component is causing
the fault.
Location LED (blue)
When activated, the Identity LED blinks at a rate of 1s on, 1s off to easily locate the chassis within a
data center. The locate function may be enabled/disabled through SES (SCSI Enclosure Services).
NOTE: Activate the Location LED by using the disk management utility (GUI) or CLI.
Unit Identification Display
The UID is a dual seven-segment display that can be used to provide feedback to the user. Its primary
function is to display a chassis unit identification number to assist users in setting and maintaining
multiple chassis systems.
Thermal sensor
The thermal sensor is located on the outside of the chassis, and it sends input to the chassis (RAID
controller/expansion IOM) about its external operating ambient temperature.
5U Chassis Ops Panel
The 5U84 chassis front panel has an Ops panel mounted on the left ear flange. A flexible cable
connects the Ops panel to the midplane. The Ops panel is a passive component: the midplane
controls the panel, and the RAID controllers or expansion IOMs control all the panel’s functions.
