MX2820 System Manual

INTRODUCTION

This section of the system manual provides details on how to prepare a Central Office (CO),
Multi-Tenant Unit (MTU), or Remote Terminal (RT) to accept the installation of one or more
MX2820 shelves. Shelves that are installed in the same bay or in adjacent bays should be
engineered together so that they share common feeds for power, timing, and management
interfaces as appropriate for the application.

PREREQUISITE PROCEDURES

Before beginning the site preparation, the Site Engineer should review the Engineering
Guidelines. Based upon the application, the Site Engineer should specify how the bay holding
the shelves should fit into the NEBS lineup for CO, MTU, or RT applications. These
considerations include which power, transmission, and clock connections are required for
each shelf.

SPACE CONSIDERATIONS

Vertical and Horizontal Space Requirements

For vertical and horitizonal space requirements, refer to the Bay Configurations figures in
"Section 2, Engineering

Use of Horizontal Spaces in a NEBS Lineup

When multiple shelves are to be installed in the same bay, horizontal aisle spacers can be
used on both sides of the bay to accommodate the high-wire density of the shelves.

Fitting the Shelf into MTU and RT Applications

For individual shelf applications, the MX2820 shelf occupies 3.5 inches of rack space. Refer to
"Section 2, Engineering Guidelines"
