Communicate with UPS condition when PowerChute plus and the

Management Card have been installed together on a UPS.

1. Ensure that the cable between the computer and the UPS (or the

expansion chassis) is securely connected at both ends.

2. Ensure that the UPS (or the expansion chassis) serial port is

connected to the same computer port used to connect the computer

to the UPS when PowerChute plus was installed.

3. If Step 1 or Step 2 did not correct the problem, reset the

Management Card.

4. If the problem persists, disconnect (or remove) the Management

Card and restart PowerChute plus.

• If the problem still persists, see your PowerChute plus documen-

tation to remove and then reinstall PowerChute plus.

• If problem clears, reinstall the Management Card.

5. If the problem still continues or returns, see APC Worldwide

2. Use an ASCII text editor to edit the [ups] section of the

PowerChute plus initialization file (pwrchute.ini or

system):

• Change the UpsPollInterval value to =6 (default value

is 4).
