WARNING!
NEVER ATTEMPT TO OPEN OR SERVICE THE POWER
SUPPLY UNIT. OPENING THE POWER SUPPLY UNIT
MAY CAUSE SERIOUS INJURY OR DEATH.
The Powered Chassis is intended to be used with two power supplies in a
power-redundant operation. A failure of a single supply should not disturb the
operation of the chassis unit. However, certain power supply failures may
cause a secondary failure to the associated fan and cause undesired
overheating of the chassis unit.
