The CertaUPS C-NMC Adapter slot-in Network Management Card receives status information from the connected UPS and can send control commands to the UPS. The UPS can be managed via a web-browser or network management software supporting the SNMP protocol. When the UPS alarms (mains failure, battery low, UPS overload, over-temperature or other settable alarm condition) the UPS can send a signal via SNMP to the connected servers for an automatic controlled shutdown. Fits C300R, C400, C400R, C500R, C500 UPS systems.
