Notes:
1. Frame width only. Additional interframe spacing of 30 mm (1.2 in) is required.
2. A top rack can optionally be installed on any HD2 frame. Side panels and PDUs are also optional. Each side
panel adds 6.8 kg (15 lb). Each PDU adds 4.5 kg (10 lb).
3. The weight with cartridges assumes a weight of .2 kg (0.44 lb) for a standard LTO tape cartridge. The actual
weight of the frame varies, depending on the configuration and cartridge capacity. Listed weights are plus or
minus 2.3 kg (5 lb).
4. Frames in position 1 (the leftmost frame in a library string) can have a maximum of 1 054 cartridges. Frames in
positions 2+ can accommodate 1 320 cartridges.

Library placement

To ensure optimal performance, the TS4500 tape library must be placed in a
location that meets certain requirements and environmental specifications.
To avoid damage to the library, tape drives, and tape media, place the TS4500 tape
library away from equipment that produces any of the following pollutants (such
as laser printers, ultrasonic humidifiers, and ionizers):
v Airborne dust
v Particulate pollution
v Corrosive fumes
Refer to "Environmental specifications" on page 86 for detailed information about
gaseous and particulate contamination.

Floor requirements

The TS4500 tape library must be placed on floor space that meets the following
specifications. Use the list of allowable variances for floor stability, unevenness,
and point load bearing qualities to determine where the TS4500 tape library is
placed.
Install the library on a raised or solid floor. The floor must have a smooth surface
and, if raised, must not have ventilation panels beneath the leveling jackscrews. If
carpeted, ensure that the carpet is approved for computer-room applications.
To accommodate unevenness in the floor, you can raise or lower the leveling
jack-screws to the following specifications:
v Maximum allowable variance must not exceed 7 mm (.27 inches) per 76 mm (3
v Maximum out-of-level condition must not exceed 40 mm (1.6 inches) over the
