PDU Installation in the 10/180 Tape Library

1. The PDU should be mounted in the bottom back of the rack. The outlets on

the PDU should face the back of the tape library. The power inlet should

be positioned on the right-hand side as you look at the back of the library.

2. Attach the PDU to the holes in the left and right rails with the Torx screws

and hex nuts (see Figure 21 on page 60).

3. Tighten the screws to force the star washers to pierce the paint and make

solid contact with the metal column. This connects the rack chassis with

earth ground to protect against possible electric shock.

4. Connect the power cables from the devices to the PDU.

5. When connecting the PDU to the main power cable, secure the cable with

the clamp. Plug the main cable into the wall outlet. Verify that the current

capacity of the wall outlet to be used will not be exceeded by the

additional devices.

6. Do not power-on the bridge(s) until the SCSI devices are connected.
