Physical and Functional Description of Router

OL-17440-01

Product Overview

This chapter provides an overview of the Cisco XR 12416 and Cisco XR 12816
Router. It contains physical descriptions of the router hardware and major
components, as well as functional descriptions of the hardware-related features.
The Cisco XR 12416 and Cisco XR 12816 Router chassis is a sheet-metal
enclosure that houses router components. The major components consist of three
power supplies, upper and lower line card cages, a switch fabric card cage, and
upper and lower blower modules. Power is distributed to these components over
the chassis backplane.
All router models contain the following major components
Power shelf and power supplies—Three AC or DC power entry modules
•
(PEMs) provide power to the router. See the
section on page 1-4
Upper blower module—Supplies cooling air to the upper half of the router so
•
it does not overheat. See the
additional information.
Upper and lower cable management brackets—Used to neatly route line card
•
cables. See the
"Upper and Lower Cable Management Brackets" section on
page 1-36
for additional information.
