External Version
It is not necessary to turn off the the UPS or its load before connecting or
disconnecting the external Call- UPS II . When connected, Call- UPS II may
cause the UPS to beep, or, if the UPS is powered off, to power on. This is
normal.
If a device such as a server or workstation is currently using the communi-
cations port on the back of the UPS , disconnect it now according to the
UPS connection instructions. Connect that device securely to the UPS
Monitoring Port on Call- UPS II . See Sec. 2.5 to determine if the optional
power adapter is required.
3.4 Confirm Operation
Observe the status indicator on Call- UPS II . After a moment it should
be on continuously. If the indicator flashes rapidly, Call- UPS II has failed
its power-on self-test. See Chapter 5.
Use only APC -supplied cables to connect the external version
of Call- UPS II to the UPS . Do not connect to any Call- UPS II port
except as specified in these instructions. Connections using a
cable or any other manufacturer may cause damage to or
improper operation of Call-
UPS II , the UPS , or the computer.
