Operator’s (Ops) panel
Overview
The enclosure front panel has an operator’s (ops) panel on the left hand mounting flange: a flexible cable
connects the Ops panel to the mid plane, as shown below in the figure. The Ops panel is a passive
component: the mid plane controls the panel and the I/O modules control all the panel’s functions. An
integral part of the enclosure chassis, it is not replaceable on site.

System power on/standby LED (green/amber)
Shows amber when only standby power is available. Shows green when system power is available.
Module fault LED (amber)
Comes on when there is a system hardware fault. It may be associated with a fault LED on a PCM, or I/O
module that helps the user to identify which component is at fault.
Logical status LED (amber)
Indicates a change of status or fault from something other than the enclosure management (EM) system.
This may be from an internal or external RAID controller or HBA, communicated to the enclosure
(normally through SES). It is usually associated with a disk drive and LEDs at each disk drive position
helps the user to identify the drive affected.
Thermal sensor
This thermal sensor is on the outside the enclosure and connects to another thermal sensor on the mid
plane of the enclosure. This external thermal sensor sends input to the enclosure about its external
operating ambient temperature. Its other function is to cause a warning signal to be generated by the SES
when there is a break in this sensor's connection to the enclosure mid plane.
Note: Refer to the section on “Ops Panel LEDs” for a description of the LED and switch functions.
