Uninterruptible Power Supply (UPS)
Introduction
The MMAC-Plus can be connected to a UPS to provide an uninterruptible source
of AC power. Two UPS models are available, the Matrix 3000 and the Matrix 5000.
Either can be monitored via remote SNMP Management after connecting the UPS
to the Environmental Module (EM).
Connecting a UPS to an EM
To connect a UPS to an EM, use the RJ-45/DB-9 adapter labeled “UPS”, the
RJ-45 cable included in the 9372089 kit shipped with the EM, and follow the steps
below.
1. Plug the RJ-45/DB-9 adapter labeled “UPS” into the receptacle on the rear of
the UPS (Figure B-1).
2. Plug one end of the cable with the RJ-45 connector into the RJ-45/DB-9
adapter labeled “UPS” on the rear of the UPS (Figure B-1).
3. Plug the other end of the cable with the RJ-45 connector into the COM2 port
on the front of the EM inserted in the MMAC-Plus Chassis (Figure B-1).
