Installation process
1.
Plug the ATX Power Supply Connector (CN1) into the Chassis Backplane Power
Connector (J1). There should be two connections on the backplane for each appropriate
power supply. Pin 1 of the Power Supply Connector CN1 should plug into Pin 1 of the
Backplane Power Connector. The two connector’s pins are keyed so if you are having
trouble making the connection, check to see if you have the pins lined up correctly.
2.
Above in Table 1 identify the chassis model to which the power supply is being replaced
and check if CN2 needs to be connected. If so follow similar steps to connect CN2 to the
backplane except CN2 will be connected to J2.
3.
If the connectors have a different number of pins, the latches will be offset and the
connector could vibrate loose. See Figure 4 below. It is necessary to apply RTV on the
seam where the two connectors attach to secure the connection.
