44 • Advanced UPSMON Configuration UPSMON User Manual
Parameter name Parameter description
Enable parallel function Enable or disable the parallel functionality.
Disable action on single Ups
If selected, the standard configuration for the single UPS event will be ignored. The Upsagent
controls only the group status. If it is not selected, the Upsagent controls, both the group events
and also the single UPS events. If this parameter is selected, the job actions defined in the job
dialog box are disabled for the single UPS.
Consider a Ups with lost
communication as an alarm If selected, the active alarm level is raised, specified on the parallel event list, for each UPS in
communication lost condition.
Disable the System shutdown from
a single UPS If selected, this disables the system and UPS shutdown time defined on the single UPS
configuration. This function shutdown time is the same time for the UPS parallel group.
Parallel Groups Used to add, modify or delete groups.
2.2.4 Parallel Groups
The name and UPS number of each parallel group, and the events associated to the parallel group are described or configured using the
next menu:
A group name must be specified, a minimum of two UPS added (from the list of UPS monitored by Upsagent, shown by selecting
“Groups UPS”) and configured the selected actions for the group events.
Parameter name Parameter description
Redundancy level
Defines the redundancy level of the parallel group: possible choices are N (default), N+1 (for
groups with a minimum of 2 UPS), N+2 (for groups with a minimum of 3 UPS) and N+3 (for
groups with a minimum of 4 UPS).
N.B. A parallel group with redundancy N+i will stay active and operational even if “i” UPS
within the group fail. The load will be shared between the remaining UPS.
Enables system shutdown in the
event of low back up time
The shutdown may depend on the fact that the “i-th” backup time of the parallel group selected
is lower than the preset time.
N.B. If the redundancy level is N, the lowest backup time is considered; if it is N+1, the second
lowest time is considered; if it is N+2, the third lowest time is considered, while if it is N+3, the
fourth lowest time is considered, on so on.
