Repeat this procedure for the other rail.
Reducing Library Weight
For weight reduction, remove the following components from each unit in the
library:
v Power supplies
v Drives sleds
18-32 kg (39.7-70.5 lbs)
svc00167
Important: Because of the weight of a multi-module library, it is strongly
recommended that you install it in the lowest position in a rack. Without
drive sleds and power supplies, a 5U library (control module) weighs
approximately 50 lbs. Without drive sleds and power supplies, a 14U
library (control module + 9U expansion module) weighs approximately 110
lbs.

32-55 kg (70.5-121.2 lbs)
Removing a Power Supply
For each power supply installed in the library:
1. Loosen the two thumb screws (
2
in Figure 3-8) on the power supply by
turning them counterclockwise.
2. To remove the power supply, grasp the handle (
1
in Figure 3-8) and slowly
pull it toward you, while supporting it from underneath.
