Replace the Fuse

CAUTION: Ensure that the power supply module has been disconnected from the external power source and the module’s On/Off switch has been set to “0”. Failure to observe this caution could result in damage to, and subsequent failure of, the power supply module.

NOTE: The power supply module may be “hot swapped” (i.e., serviced while the chassis is in operation) provided the module to be serviced has been disconnected from its external power supply and the module’s On/Off switch has been set to “0”.

To replace the fuse in the CPSMP-130 or CPSMP-140 power supply module:

1.Set the On/Off switch on the power supply module to “0”.

2.Verify that the external power source is NOT powered.

3.Disconnect the positive (+) DC terminal from the external power connector marked “+”.

4.Disconnect the negative (-) DC terminal from the external power connector marked “-”.

5.Disconnect the ground terminal from the external power connector marked “chassis ground”.
