Introduction
Overview
CR6400 Routers
Note: the CR6400 Family Users Guide offers complete detail.
The CR Series routers are 2RU routers. They are about 10” deep to accommodate removable I/O
cards. This is a front view of the router:
The CR6464-3Gig and the CR6464-AES routers have the same features at the front. The two
routers are distinguished, at the rear, by the labeling on their I/O cards.
The router’s fan module is removable through the front of the router.
At the rear, the CR Series routers have 4 slots for removable I/O cards, and slots for a crosspoint
card and a control card (also called a CPU card).
Each I/O card has 32 ports. There are 16 input ports on the left (as you face the rear of the router)
and 16 outputs on the right. The connectors for both the 3Gig card and the AES card are DIN 1.0/
2.3 connectors (which we usually call “coax” connectors).
The port numbering at the rear of the CR6400 routers is simple:
It is 1–64, top-to-bottom, on the left for inputs and 1–64, top-to-bottom, on the right for
outputs.
At this revision, the router must contain only 3Gig cards or only AES cards. It may contain from 1
to 4 cards. If the router is populated with 3Gig cards, the router is considered a CR6464-3Gig and
switches video. If the router is populated with AES cards, the router is considered a CR6464-AES
and switches audio. A router having no cards is considered to be of “undefined” type.
