About the Expansion Module
An expansion module provides additional cartridge storage and tape drive capacity.
Expansion modules are installed below the base module. The base module connects to
each of the expansion modules using a USB Type A connector.
Expansion modules ship without tape drives or power supplies. The expansion
module can contain up to two drives and two power supplies. If there is no tape drive,
the expansion module can operate off of the power provided by the USB cable, it does
not require a power supply. If you install a drive in the expansion module, you must
also install at least one power supply. You can add a second power supply for
redundancy, however one power supply can provide power for two drive.
Each expansion module requires 2U of rack space. An expansion module ships with:
Two 15-slot tape magazines (left and right)
■
Module controller
■
Expansion cable that has two USB Type A connectors
■
Mounting hardware to secure the module to the rack
