frames constitutes a single unified network element with a unique Ethernet

address. For more details, refer to the Cisco Metro 1500 Series Software

Configuration Guide.

Chassis

Each chassis of the Cisco Metro 1500 series can be mounted in a 19-inch cabinet

or in open racks. Each chassis requires five rack units. The chassis houses all of

the system modules required to achieve the optical communications link.

This section describes the following chassis components:

•Dimensions

•Labeling

•Airflow System

•Power Supply Module

Dimensions

The housing is modular in accordance with DIN specification 41494 part 5. The

construction comprises two aluminum sides and four aluminum cross extrusions.

Standard features also include sheet-steel covers and die-cast aluminum cover

extrusions. All covers are uncoated aluminum; cross extrusions, side extrusions,

and handles are textured powder-coated. Figure 1-8 shows the dimensions of

the chassis.
