mixed media configuration, the upper I/O station is the media type of the Lxx frame
and the lower I/O station is the alternate media type.
• Operator panel
• Operator panel controller
The high availability frame contains a rail assembly and gripper test slots.
All components of the TS3500 Tape Library are contained inside the frames. The tops of the
frames have windows that admit ambient lighting, except for the HD frames, which are
outfitted with LED lighting. Windows are also located at each end of the library.
Located at the front of each frame is a front door. The door lets you access the cartridge
storage slots and allows service personnel to access the rail assembly, cartridge accessor,
and accessor controller. The front door of the base frame includes the operator panel, power
switch, I/O stations, handle for opening the door, and keylock. The front doors of the
expansion frame and the high availability frame include a handle and a keylock.
Inside each base frame and expansion frame, cartridge storage slots are mounted on the
interior of the front door. Opposite the front door, cartridge storage slots and drives are
mounted on the frame wall. The cartridge accessor accesses these storage slots and drives.
For more information about HD frames and HD technology, see High density technology. For
more information about frames used as service bays, see Dual accessors and service bays.
At the rear of each frame is a service access door that lets service personnel access the
tape drives and the power structure (see 1 in Figure 1). For Models L22, D22, L32, D32,
L52, and D52, the power structure is called the frame control assembly. It comprises a
sheet-metal unit that houses circuit breakers, ac outlets for powering the tape drives and all
other components in that frame, and a receptacle for the incoming main ac power. For
Models L23, D23, L53, and D53, the power structure is called the enhanced frame control
assembly. It comprises a separate device called the Medium Changer assembly, as well as a
sheet-metal unit that houses power supplies, and incoming main ac power.
Up to 15 expansion frames can be added to the base frame. An additional expansion frame
is added as a service bay in a high-availability library. Expansion frames are attached to the
right of the base frame (as you face the operator panel), and are numbered consecutively
from left to right. For more information, see Structure of the library.
The IBM® System Storage™ Tape Library Specialist Web interface and 10/100 Ethernet
support are included with Models L22, L23, L52, and L53. For Model L32, they are available
as feature codes 1662 and 1660, respectively.
