C.1 Overview
An Uninterruptible Power Supply (UPS) is used to protect data integrity
during abnormal power loss. If you lose AC power , the UPS should provide
power to the OSx station for a minimum of 20 minutes.
Figure C-1 shows cabling arrangements for a typical UPS system.
T o properly maintain your system (single-station system), install a
minimum of a 2 KV A system.
If you need additional help in selecting or installing a UPS, contact your
supplier.
A 2 KV A (minimum) UPS provides sufficient emergency power for a
single-station system (monitor , system unit, and printer). Install a second
power strip in back of the system to provide this emergency power .
Figure C-1 shows cabling connections for both primary and UPS power
using a 2 KV A system.
