Installing the DC Power Supply Unit
To install the -48 Volt DC power supply unit:
1. Make certain that the ON/STANDBY switch on the unit is in the STANDBY (O) position.
2. After removing a blank faceplate that covers a power supply slot, carefully slide the power supply into
the selected slot of the 8265 chassis.
3. Fasten the power supply to the 8265 by tightening the two spring-loaded screws on the power supply
faceplate. Ensure that both screws are securely fastened (tighten the screws to 3 to 5 inch pounds).
4. Plug the keyed-connector into the power supply socket.
Figure 13 shows the power supply keyed-connector with strain relief.
