Power Distribution Unit Installation (PDU)

PDU Installation in the 20/700 Tape Library

Note The power distribution units (PDUs) may be different for the FC

2/1 LV and 4/1 HV. The PDU ordered with the FC 4/1 HV may

have only seven outlets, the PDU for the 2/1 LV has ten outlets.

Either PDU can accommodate both the FC 2/1 LV and the FC 4/

1 HV bridges.

Note The power distribution unit (PDU) for the 20/700 must have the

outlets facing up when using either the FC 2/1 LV or the FC 4/1

HV. (See Figure 20 on page 59.)

Install the bridge 2 EIA units above the PDU in order to allow

enough room for the power cables to be inserted into the PDU

outlets. By not having the outlets facing up, the PDU will prevent

the back door from closing.

1. The power distribution unit (PDU) should be mounted at the bottom back

of the rack. The PDU mounting brackets should be positioned so that they

are on the inside of the rack column. The outlets on the PDU must face the

top of the accessory rack. 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 20 on page 59).
