Install an expansion (lower) power supply

Note: This procedure is required only if you are upgrading a 4- or 6-drive system to a 10-drive

system.

To install an lower power supply:

1. Place the lower power supply on the brackets below the existing power supplies (see

Figure 1).

2. Secure the lower power supply to the jukebox using 2 T-20 torx screws (at the top corners

of the power supply).

3. Connect the power switch cable to the lower power supply (see Figure 4).

4. Connect the DC power cable to the lower power supply.

5. Route the bundled power supply cables (item 4 in Figure 4) to the right of the lower power

supply, below the lower power supply and the drive bays, to the interposer board.

Note: The cable ties have buttons that snap into the jukebox chassis, guiding the cables to their

proper location and keeping them secure and out of the way.

6. Connect the bundled power supply cables to the lower interposer board, as dictated by the

lengths and connection types.
