3. Operation (continued) 3.4 Rear Panel Accessory Card Slot: Remove the cover panel from this slot to install an optional internal SNMPWEBCARD or RELAYIOCARD accessory, sold separately. SNMPWEBCARD provides a network interface for monitoring and control via SNMP, Web or telnet, enabling remote reboots, shutdowns and more. RELAYIOCARD provides a programmable contact closure interface with 6 outputs and 1 input. External Battery Pack Connector (Configuration Varies By Model) Fan: The fan cools the UPS system's internal components. It is always on when line power is present, even if power to the UPS system's outlets is turned off. Output Circuit Breakers (Select Models Only): These resettable circuit breakers protect the UPS system from output overload. If a breaker trips, remove some of the load on the circuit and allow the UPS system to cool before pressing the breaker button to reset. Input Power Cord: This permanently attached power cord connects the UPS system to a compatible power outlet. NEMA L5-30P NEMA L5-30R NEMA 5-15/20R AC Outlets (Configuration Varies By Model): These outlets provide connected equipment with pure sine wave AC output derived from the AC line during normal operation and derived from battery power during blackouts and severe brownouts or overvoltages. Output power is filtered to protect connected equipment against damaging surges and line noise. The outlets are divided into numbered load banks, as labelled on the unit. Using included PowerAlert software and cabling or an optional SNMPWEBCARD, load banks may be individually turned off and on from a remote location, allowing users to reset or reboot connected equipment.
