Power Supply

Built into the CS-52xx chassis, the 40 W power supply provides power ot the chassis and
modules. The chassis must be connected to an isolated, dedicated, 105–125 VAC, 15 A
(minimum), 57–63 Hz, single-phase commercial power source through an uninterruptible power
supply (UPS). The system power supply provides +5 VDX, 4 A output.
Built into the DEI chassis, a 100 W power supply provides power to the chassis and modules.
For universal operation, each chassis must be connected to an isolated, dedicated, 90–240
VAC, 15 A (minimum), 50/60 Hz, single-phase commercial power source through a (UPS). The
DEI power supply provides +24 VDC, 5.3 A output. For expanded applications, all required
power transformers should be plugged into appropriate power sources. For details, refer to the
equipment manufacturer's documentation.
NOTICES
Do not use an extension cord.
Do not plug any other equipment into the outlet where the UPS supporting the Base Server
or DEI is plugged-in.
Do not defeat, or leave floating, the ground wire in the AC power cord.
In addition to the system power back-up, a rechargeable battery located on the system
Processor Module backs up the database. In the event of a power failure or brownout condition,
this battery supports the module for up to one day. The battery automatically recharges when
power is restored to the module.
