SNMP Communications Option
The UPS provides an intelligent slot for internal or external network card . This special intelligent network card can be compat-
ible 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 .
Emergency Power Off (EPO) Port
A customer supplied switch located remotely can be used to close the EPO connection and allows the UPS output receptacles
to be switched off . Since the EPO 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 .
Keep Pin 1 and Pin 2 closed for UPS normal operation . To activate EPO function, open the wire between Pin 1 and Pin 2 .
