2.4 UPS Cable [External Version]
Use this cable to connect Call-UPS II to an APC Smart-UPS, Matrix-UPS,
Symmetra Power Array or other
APC smart device (Share-UPS or Triple
Chassis, for example).
2.5 Power Port [External Version]
The external version of Call-UPS II has a power port for an optional
power adapter. This adapter is not needed in most situations. Call-
UPS II
normally receives power from the UPS through the UPS connection cable,
giving Call-
UPS II protection from poor power conditions. After UPS
shutdown for low-battery condition, Call-UPS II will still draw power
from the
UPS for a time determined by the size of the load and the capac-
ity of the
UPS. However, Call-UPS II stops drawing power from the UPS
before the battery is completely drained.
To determine whether a power connector will be useful, refer to the two
paragraphs that follow. You can obtain a power adapter by contacting
APC technical support at one of the numbers given on the back cover of
this manual. The
APC part number for the power adapter is AP9505.
With Smart-UPS
The optional power adapter is required for some older Smart-UPS models
that do not supply power to Call-
UPS II. To determine whether your
Smart-
UPS supplies power to Call-UPS II, refer to the Smart-UPS user
manual. Plug the adapter into a wall receptacle if you want remote turn-
on and turn-off capability; otherwise, plug it into a Smart
-UPS receptacle.
(Smart-
UPS models 250, 370, and 400 cannot be turned on or off by
remote connection; for these models plug the adapter into a Smart-
UPS
receptacle.)
With Matrix-UPS
You will need the optional power adapter for use with Matrix-UPS only
if you want remote turn-on capability. Matrix-
UPS can be turned off
remotely by Call-
UPS II, but, without the adapter, Call-UPS II will then
lose power. The
UPS will execute a Graceful Reboot command (item 5 on
the
UPS Control menu of Call-UPS II ) without causing Call-UPS II to lose
power. Plug the power adapter into a wall receptacle if you want remote
turn-on and turn-off capability. Otherwise, plug it into a Matrix-
UPS
receptacle.
