About Refurbished Products

Refurbished products are typically refurbished by an Original Manufacturer or an affiliate of the manufacturer or 3rd party facility. This product may have minor blemishes due to normal product usage and doesn't necessarily come with documentation and software unless indicated, but has been well tested and generally has never had any defects.

For all your expansion module needs, we've got you covered with high-performance devices that increase functional capability and ease business processes.

You can talk to any of our staff and consult on what would be the best way forward when getting an expansion module to complement and enhance existing infrastructure and meet your immediate and future needs.

We have hardware level 12 with firmware 3.0 or higher modules that allow for the installation of up to 14 expansion modules below the base module for resilient performance. Expansion modules connect to the base module using USB Type-A connectors. That's not all, we have hardware level 11 and lower that supports up to 9 expansion modules.

With an expansion module, you get additional cartridge storage as well as tape drive capacity. We have expansion modules that contain up to two drives and two power supplies.

However, you can add a second power supply for redundancy purposes. Without a tape drive, the expansion module is powered via the USB cable connected to the base module.

Expansion modules require 2U rack space and will be shipped with the necessary mounting hardware used to secure them to the rack.
