Drive Enclosure Operation

7.1 Before You Begin

Before powering up the enclosure, please ensure that all the modules are firmly seated in their correct bays.

7.2 Power On / Power Down

Caution Do not operate the subsystem 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.

To Power On the enclosure.

• Apply AC power to the enclosure. Turn the PCMs to ON.

All LEDs on the I/O Panel should be lit (Green) when the enclosure power is activated (and the disk drive motors should start).

Important If AC power is lost for any reason, on restoration of power the enclosure will re-start automatically.

To power the enclosure down:

•Switch off the PCMs installed in the enclosure.

7.2.1PCM LEDs

The PCM incorporates 4 LEDs, located above the On/Off switch. Please refer to Figure 5–4and Table 5–2.
