Select the UPS vendor for your UPS device. Vendors APC and MGE are available.

UPS mode

Single

This option determines that the server is the only system attached to this UPS and that there is no action necessary to do a remote shutdown for other systems in the network.

Server

This option determines that the server is connected to the UPS and sends a signal through the network to shut down other systems in the network.

Client

This option determines that the server reacts to a power down-signal from the UPS server.

When using an APC-originated device with the Server UPS mode server net port is fixed and set to 3551.

When using an APC-originated device with the Client UPS mode enabled the following fields are available:

Server Net port

TCP port on which the  UPS client is connecting to the UPS server.

Server IP

IP address of the master APC UPS.

When using an MGE-originated device with the Master UPS mode enabled the following fields are available:

User name

User name allowed to connect from the slave UPS.

Password

Password for the user name above.

Slave IP

IP address of the slave MGE UPS. It is possible to specify multiple addresses separated by semicolon.

When using an MGE-originated device with the Slave UPS mode the following fields are available:

Timeout

The timeout defines the time between a power failure and the moment the system shuts down.

Timeout - Battery Limit

This option enables you to sustain the system as long as the battery holds (the system will shut down when the battery charge drops to 5% or when there are 3 minutes left to total battery discharge).

APC - This option works for all Smart UPS models and dumb UPSes with cables that support low battery detection (only testing can determine this point).

Turn off UPS after system shutdown

This will turn off the UPS device after the time period set in the Shutdown grace delay (SLEEP) parameter in the UPS EEPROM expires.

Note

When using slave and master UPS modes, all UPS devices need to come from the same vendor.
