Chassis Number Ranges

 

The chassis number specifies the chassis within a system.

Table 1: Chassis Numbers

Chassis number

Passive equipment

Note: The chassis number for passive equipment is conceptual. Passive equipment does not reside in a chassis.

Main (or hub) chassis

1

Satellite chassis

2

Note

This document distinguishes between a chassis number and a chassis identifier. The chassis identifier is a self-contained addressable entity whereas the chassis number is not. The chassis number is part of the chassis identifier. For example, chassis:1 is a chassis identifier with a chassis number of 1.

Note

There is no chassis identifier called chassis:0. When you add a passive module, you do not specify a chassis identifier. However, you do specify a chassis number when you refer to passive equipment. For example, md:0/3 is a valid passive equipment identifier.
