DSS-1 and DSS-2 Hardware Description Product Overview
Power Supply
NOTE:
Proper drive cooling requires adequate airflow. Never operate the
DSS-IIDSS-2 without the enclosure top panel in place. Always
cover any open drive slots in the enclosure front panel to avoid loss
of airflow through operating disk drive canisters. Never block
airflow through the front panels of either the enclosure or the disk
drives.
The two DSS-lIDSS-2 power supplies, shown in Figure 8, are connected in
parallel; each is capable of providing power for all drives within the enclosure.
This redundant (N+ 1) configuration enables the disk drive subsystem to continue
operating if one of its two power supplies fails and needs to be replaced.

Each power supply has an ON/OFF power switch that is accessible from the rear
of the enclosure. A green power-on indicator, which is part of the DSS-IIDSS-2
enclosure, indicates a functioning power supply.
