About the XR Series Systems
The XR Series Systems are based on the VMEbus backplane
architecture and the Modular Chassis family of enclosures, power
supplies, and SCSI storage subsystems.
❏
Modular Implementation
The XR family includes 3-slot, dual 9-slot, 12-slot, and 20-slot
systems. Each system is designed as a set of modular building
blocks that can be readily adapted and recombined to meet
the needs of technical, industrial, and telecommunications
applications.
The dual 9-slot, 12-slot, and 20-slot systems offer freestanding
pedestal, frame or rack mount options. The 3-slot system is
designed for either frame or rack mount options.
This building-block approach is designed to provide OEMs
and system integrators with the maximum amount of
packaging flexibility.
❏
Simplified Design
The design minimizes screws, wires, and cables necessary for
building a system while maximizing maintainability and
reliability for the end user. It removes the necessity for
adapter cards and cables between the transition modules and
the backplane.
❏
Resilient Implementation
The XR family of systems is designed to comply with
telecommunications industry requirements. The dual 9-slot
system offers the ability to create redundant systems in a
single chassis.
