SNMP Communications Option
The UPS provides an intelligent slot for internal or external network card. This special intelligent network
card can be compatible with popular software and hardware found on the web and in operating
systems. It can support operating systems such as HP Open View, IBM Netview, SUN Netmanager, etc.
This enables the UPS to provide instant UPS and power information over the network. Please contact
your reseller for additional details.
Remote Emergency Power Off (REPO) Port
A customer supplied switch located remotely can be used to close the REPO connection and allows the
UPS output receptacles to be switched off. Since the REPO shuts down the equipment immediately,
orderly shutdown procedures are not followed by any power management software. The UPS will have
to be manually restarted in order to regain power to the outlets on the UPS.
