DESCRIPTION
1
Outlets
Connect equipment to the uninterruptible power supply.
2
Output Circuit Breakers
Each circuit breaker protects its nearest outlet.
3
EPO Terminal
The optional Emergency Power Off (EPO) feature enables connected
loads to be immediately de-energized from a remote location, without
switching to battery operation. See
Emergency Power Off (EPO) Option
.
4
Bypass Switch
This switch will put the unit in bypass mode. See

5
Serial Port
Power management software and serial port communication can be used
with the uninterruptible power supply. Use only cables supplied or ap-
proved by IBM.
Note:
Use the supplied serial cable to connect to the serial port.
Do not
use a standard serial interface cable because it is incompatible with the
uninterruptible power supply connector.
6 Integrated
Environmental
Monitor
This Network Management Card monitor features a tempera-
ture/humidity probe, two input contacts, and a two-position output relay.
For information on connecting and using the probes, contacts, and relay,
see the
Network Management Card CD.
