Door safety switch
This section describes the safety switch located on the doors of TS3500 Tape Library
frames.
Each frame in the TS3500 Tape Library (excluding the service bays) has a door safety
switch that automatically turns off the power to the cartridge accessor (but not the tape
drive) whenever you open the front door. The power does not automatically turn off if you
open the rear door. The action of automatically turning off the power to the accessor is
modified for the service bays if the IBM® Service Representative has installed the safety
barrier. After you close the front door, the library automatically performs an inventory of the
tape cartridges of that frame.
I/O stations
This section describes the Input/Output (I/O) stations of the TS3500 Tape Library.
Note:
In the TS3500 Tape Library, place only LTO Ultrium tape cartridges into Ultrium
frames with black, Ultrium-supported I/O slots; place only 3592 tape cartridges into 3592
frames with gray-supported I/O slots.
The I/O stations let you insert or remove cartridges while the TS3500 Tape Library is
performing other operations.
The TS3500 Tape Library comes with one 16-cartridge I/O station. To add greater capacity,
you can order additional 64 or 16-cartridge LTO I/O or 3592 I/O stations to be installed by
your IBM Service Representative.
TS3500 Tape Library supports four I/O stations in newly purchased Models D23 or D53
frames. The D-frame with I/O installed is comprised of four independently accessible I/O
station doors that have a total of 64 slots (16 in each I/O station). Additionally, two LED
indicators are provided for each I/O station in a D-frame in order to indicate if the I/O
station is empty or full and if the I/O station door is locked or unlocked. This plant feature
reduces the frame storage slot capacity by 160 for a Model D23 and by 176 for a Model
D53. The I/O stations increase the maximum library I/O slot capacity from 32 to 224 due to
a maximum of three D23 or D53 I/O frames in a 16-frame library. The multiple I/O stations
double the maximum insert/eject throughput. The newly purchased D23 and D53 Models
remain compatible with existing Models L22, L32, L52, D22, D32, and D52. For a graphical
