Drive Power
The drive voltage backplane sensors (+5.1 VDC and +12.1 VDC) can detect a
drive overcurrent condition. When a drive overcurrent condition exists, the sensor
disconnects the voltage from the drive to prevent writing data to the drive. The
drive is disabled until one of the following conditions occurs:
■ The defective drive is replaced.
■ The overcurrent condition no longer exists.
Drive Blank
To maintain the proper enclosure air flow, you must have a drive or a drive blank
in each drive bay. The function of the drive blanks is to control air flow within a
bay. See
Figure 38 .
