Chapter 4. Operation
Powering on
About this task
Before powering on the enclosure system, make sure that all modules are firmly seated in their correct
bays. Verify that you have successfully completed the sequential instructions in the section covering
installation planning.
CAUTION: Do not operate the enclosure system until the ambient temperature is within the
specified operating range described in the Environmental requirements section. If the drive
modules have been recently installed, make sure they have had time to adjust to the
environmental conditions before they operate.
Procedure
1. Power on the system by connecting the power cables to the PDU and moving the PCM switch to the
“on” position.
See the Power cord connection section.
2. The system power LED on the ops panel should be lit green when the enclosure power is activated
(and the disk drive motors should start).
Important: If mains power is lost for any reason, on restoration of power the system will re-start
automatically.
Note: Refer to the section on Initial start-up problems for details of the ops panel LEDs and related
fault conditions.
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.
