operating instructions, and support information for the XR900
series SCSI standalone peripheral expansion enclosure.
Throughout the rest of this manual, this enclosure may be referred

General Description
The XR900 is a member of the Modular VME System, a family of
standard chassis building blocks that can readily be adapted and
recombined to meet the needs of standard system customers,
component-level chassis customers, and buyers of special system
configurations for technical, industrial, and telecommunications
applications. Although the XR900 can be operated with any SCSI-
compatible host, it is used most effectively with other Modular
VME System units.
