DSS-1 and DSS-2 Hardware Description
Each power supply may contain a voltage select switch (labeled 1151230) that
is located just above the power cable connector. Make sure this switch is set for
the proper line voltage (230) before you tum on the power supply.
CAUTION
Ensure that the voltage select switch (above the power cable
connector) is set to the proper voltage (230). A power-on with
an incorrect voltage setting damages the power supply.

Each power supply is hot swappable, which means that it may be turned off,
unplugged, and replaced without affecting normal system operation. The only
requirements for this feature are that the remaining power supply is functioning
properly and that the replacement sequence does not result in the rear panel being
open for more than a few seconds because of the constant airflow that is required
for adequate drive cooling.
The power cable to the power supplies is a V-configuration, which enables either
power supply to operate in the absence of a power connection to the other. The
upper, power-out daisy chain connector should not be used in the DSS-IIDSS-2.
