Library Power Requirements
Component
Base module (one power supply)
Expansion module (no power supplies or drives) 1
Tape Drive (each)
Additional Power Supply
For volt-amp (VA) measurements, add 2 percent to the Watt value.
For Btu/hr, multiply the total wattage number by 3.414.
Refer to the power calculator at:

A minimum library configuration has a total idle power of 44 W (150 Btu/hr) and a
steady state maximum of 67.5 W (230 Btu/hr).
A ten module library with 20 tape drives and 20 power supplies has a total idle power
of 338 W (1154 Btu/hr) and a steady state maximum of 751 W (2564 Btu/hr).
Library Cartridge Capacity
Cartridge capacity depends on the base module hardware level and software version:
Hardware level 12 and 3.00 software supports one to 15 modules, one to 450 tape
■
cartridges, and one to 30 tape drives.
Hardware levels up to 11 and software up to 2.6 support one to 10 modules, one to
■
300 tape cartridges, and one to 20 tape drives.
The following table shows the number of Storage, Mailslot, and Tape Drive slots as
Expansion Modules are added to the library configuration.

Modules
Base Module
Base Module plus one expansion module
Base Module plus two expansion modules
Base Module plus three expansion modules 1200
Base Module plus four expansion modules
Base Module plus five expansion modules
Base Module plus six expansion modules
Note:
You cannot upgrade older hardware to level 12. You must
order a new library to have hardware level 12.
