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 drive is replaced, if defective.
• The overcurrent condition no longer exists.
Drive blank
To maintain the proper enclosure air flow, a drive or a drive blank must be installed in each drive bay .
The drive blanks (see Figure 29 ) maintain proper airflow within the disk enclosure.
