Uninterruptible
Power Supply
An Uninterruptible Power Supply (UPS) is provided with each Information Center and
Database Server. It provides up to 90 seconds of battery power to maintain system operation
and eliminate time consuming software rebooting during short power transitions (e.g. power
generation tests).
Caution The Philips 9 pin UPS communication cable (gray) must be used when connecting the
devices to the UPS. Do not use the black COM cable that ships with the UPS.
Warning UPSs are shipped without their internal battery wire connected. Before use, the battery
wire must be connected.
Only Voltage Outputs labeled BATTERY BACKUP should be used for UPS protection.
The UPS for the Information Centers, Clients, Patient Link and M3169 Database Server
is rated at 650 VA and comes in three versions -- 100-127 VAC (50/60 Hz), 100 VAC (50/
60Hz), and 220-240 VAC (50/60 Hz). The versions look similar and are shown in Figure 2-25
along with typical UPS front and rear panels.
