Uninterruptible power supply
A recommended uninterruptible power supply (UPS) may be used for power holdover. The type of UPS
depends on the holdover requirements. Total holdover capacity varies depending on the UPS. The UPS
must provide surge protection for the CMC1 cabinet.
CAUTION:
The major-alarm contacts should only be connected to a UPS that can indicate its backup
power status. For most non-Avaya UPSs, you should not use the major external device
leads. Using these leads for anything else could cause an SPE download.
1 Connect the UPS to an electrical outlet capable of handling the power requirements of the
cabinets:
a 100 VAC, 4.5 Amps
b 120 VAC, 3.8 Amps
c 200 VAC, 2.3 Amps
d 220 to 240 VAC, 2.0 Amps
2 Ensure that the cabinet is connected to an “unswitched” or “always-on” electrical outlet on the
UPS.
3 For an Avaya-provided UPS, connect and administer the UPS. See Connect external alarms and
auxiliary connections on page 113.
NOTE:
If an Avaya-provided UPS is wired as recommended, holdover time for each power outage
is 1 minute before an automatic shutdown. The UPS may handle any subsequent power
outages based on its total battery capacity.
Cabinet’s power switch
!
DANGER:
The latch acts as the DC power switch and only removes DC power from the cabinet,
not AC power. To remove AC power, pull the AC power cord from the appliance
inlet. See Figure 62, CMC1 power supply,
on page 360.
