Connect Power and Networking to Monitoring System
The connection points for power and network are located on the left rear side of the cabinet as shown
below.
The monitoring system requires a supply voltage of 100 - 240V, 50/60Hz. The power inlet on the two,
redundant, hot-swappable power supplies in cabinet is a C14 male and requires a power cord with a C13
connector. The power cable is customer supplied to match the sockets on the power distribution units
(PDU) of the rack. After connecting the power cord, secure it with the cable relief.
To add the monitoring system to a network, connect a shielded F/UTP network cable with shielded RJ45
connectors to the port at the top left of the monitoring system box.

Party External Leak Sensors (Optional(out of support by FUJITSU))
Up to two optional 3
rd
party external leak sensors can be connected to the CDU Cabinet. These external
leak sensors must have one of the following types of output:
An open collector output
A relay output which connects the output to ground.
A digital high/low signal, with a high voltage between 3V and 5V.
The sensor output must be active low when the sensor is DRY. The output must be high or open when
sensor is wet. Sensors with analog output cannot be used.
There is a 12V DC supply available for the sensor. Each sensor port can deliver max 150mA.
The external sensors are connected to the monitoring box as shown on the picture below.
