Communication Lost alarm
The activation of the ‘Communication Lost’ alarm signals a problem in the communication between the
Adv. SNMP card and the UPS. The possible causes for the alarm are the following:
-
Communication with the UPS is lost or could not be established
-
Configuration error: there is a collision in the SNMP card address configuration
If the alarm is activated, verify that the card is installed and configured according to the instructions
included in Chapter 4-INSTALLATION.
Note: The Green LED on the front of the SNMP card adapter gives indication on the status of the
communication with the UPS:
-
LED on and stable: no communication with the UPS
-
LED blinking slow (1/sec.): communication with the UPS OK
If two SNMP adapter cards are present in the system (whether plugged in the same unit or plugged in
different units within the same parallel system), there may be an address collision – that is, two or more
cards have been configured with the same logical address.
Check the SNMP card logical address. The address can be set via an HW configuration (jumper J5, J6 –
refer to Chapter 4-INSTALLATION) or SW configuration (O.CardAddr option, refer to Chapter 7-
CONFIGURATION OPTIONS).
Note: the SW configuration can be set to 0-autoselect (the board address is determined by the jumper
settings); otherwise the SW configuration overrides the jumper settings.
