IBM TotalStorage 3494 Tape Library, Operator'S Manual

Page: 37 / 605

Figure 10 on page 12 shows the rear (without the rear door) of the 3494 D2x
Frame. This example shows eight 3592 Tape Drives, a 3592 J70 Controller, and the
following functional components:
1
Cartridge Storage Cells
The cells are located on the inside of the front door and on the back wall
of the 3494 D2x Frame.
2
Rail System
The rail system carries the cartridge accessor through the 3494 Tape
Library. The rail system consists of two horizontal rails, one at the top and
one at the bottom of the 3494 D2x Frame.
3
Primary Control Compartment
The primary control compartment distributes power to all components in
the frame. With FC 1901, Dual AC Power, installed (as shown in Figure 10
on page 12), there are two primary control compartments. If FC 1901 is not
installed, only the lower primary control compartment is present.
4
3590 A60 Controller or 3592 J70 Controller
The 3590 A60 Controller or 3592 J70 Controller consists of a RISC processor
and associated adapter cards.
5
Tape Drive Power Supplies
A redundant pair of power supplies delivers power to the 3592 Tape
Drives. The AC power cord of each power supply plugs into the primary
control compartment. The power supplies convert input AC power to the
DC voltages necessary to operate the 3592 Tape Drives.
