4 Operation
Before You Begin
Before powering up the SR1202 enclosure please ensure that all the modules are firmly seated in
their correct bays.
Power On
!
CAUTION
Do not operate this equipment until the ambient temperature is within the specified operating range.
If the drives have been recently installed ensure they have had time to acclimatize before operating
them.
NOTE
Please refer to section “Ops Panel LEDs” on page 40 for details of the Ops Panel LEDs and related
fault conditions.
Follow the procedure below to Power On the enclosure.
1. Apply AC power to the enclosure. Turn the Power Supply modules to ON.
2. The Power On LED on the Ops Panel should be lit (Green) when the enclosure power is
activated (and the disk drive motors should start).
NOTE
The Power On LED on the Ops Panel should be lit Green at power up to indicate that the system
is functioning correctly, all other Ops Panel LEDs are off. If any LEDs show Amber then a problem
exists and the procedure in Chapter 5 should be followed.
!
IMPORTANT
If AC power is lost for any reason, on restoration of power the enclosure will re-start automatically.
NOTE
Please refer to section “LEDs” on pages 40–42 for LED status conditions.
Starting the Drives
Unless otherwise selected during installation, all drives in the enclosure should automatically start
their motors. If this has not occurred one of the following conditions may exist:
• There may be a power problem (an alarm and power fault indication would normally be active).
• If there is only one Power Supply Module present, the drive motors will spin up in a delayed
sequence.
Disk Drives LEDs
Each drive carrier incorporates two indicators, an upper (GREEN) and lower (AMBER).
• In normal operation the Green LED will be ON and will flicker as the drive operates.
• The Amber LED will be OFF In normal operation. It will only be ON if there is a drive fault.
• If the Green LED is OFF when the Amber LED is ON, a power control circuit failure is
indicated.
