DC Power Module

DC Power Module
The ONS 15454 M2 system can be powered by redundant DC power lines, however a single power line can
power the entire ONS 15454 M2 system. The DC power module draws the power from the batteries to turn
on the ONS 15454 M2.
Each ETSI DC power module has:
• Two input battery connectors (two poles): -48V, RET for power terminals A and B.
• One RJ-45 port for EMS connection
• One USB port to support passive unit remote inventory connection
• Two BITS connections (IN and OUT) for network synchronization that is supported by mini BNC
Each ANSI DC power module has:
• Two terminal block connectors with -48V, RET for power terminals A and B
• One RJ-45 port for EMS connection
• One USB port to support passive unit remote inventory connection
• Two BITS connections (IN and OUT) for network synchronization supported by four wire-wrap pins
The DC power module has a single dual-color (red and green) LED on the faceplate. When the battery is not
connected, the LED is OFF. Green LED indicates that the battery is connected and the power module functions
properly. Red LED indicates that the battery is connected but an alarm is present due to secondary fuse break
(48 V). The DC power module does not support the lamp test procedure.
The fork or ring terminals used on the DC power modules are not available from Cisco, but they are available
commercially. Ensure that the hole size of the fork terminal or ring terminal is greater than 3.5 mm and width
is less than or equal to 7 mm. The minimum acceptable cable size is #14 AWG. The fork terminal must be
insulated and UL listed.
