Liebert MultiLink

Liebert MultiLink monitors the UPS continuously and can shut down the computer or server in the event of
an extended power failure. Liebert MultiLink can also be configured to shut down the UPS.
Liebert MultiLink can communicate with the UPS via the USB port, RS232 port, contact closures via
terminal block or over the network via SNMP using the Liebert IS-WEBCARD. An optional Liebert MultiLink
license kit permits shutting down multiple computers that are protected by the UPS.
