Control Module; Expansion Module - Quantum Scalar 1000 Operator's Manual

2-6 System Description

Control Module

The CM is a single module, standalone Scalar 1000 library. It
contains an Operator LCD panel, AC and DC power supplies,
robot control electronics, and host interfaces. It can be
attached to an EM to create an expanded Scalar 1000 library.
The CM differs in tape and drive bay capacity. See Figure 2-1
on page 2-5.
Each drive bay has the space equivalent of 48 LTO, 40 SDLT,
44 3590, or 60 AIT cartridges. Each drive bay accommodates:
• One or two 3590 or High Profile DLT tape drives
• One to six DLT/SDLT or LTO tape drives
• From 1 to 12 AIT tape drives

Expansion Module

The EM extends the length of the aisle and adds drives and
cartridges to the library. The Scalar 1000 maximum
configuration includes three EMs. These modules extend the
X-rails (top and bottom) which allow the Accessor to travel
the length of the library. See Figure 2-1 on page 2-5.
