Chapter 1 Cisco XR 12406 Router Overview
Line Cards
Cable-Management System
The Cisco XR 12406 Router cable-management system organizes the interface cables entering and exiting the system, keeping them free of sharp bends and out of the way.
Caution Excessive bending in an interface cable can degrade performance.
The cable-management system (Figure 1-12) consists of the following components:
•One vertical cable-management bracket on the chassis
•One line card cable-management bracket on each line card
When you face the front of the router chassis, the chassis cable-management bracket is installed on the left side of the chassis, adjacent to the line card and route processor card cage. The chassis cable-management bracket organizes the line card and route processor cables to keep them from binding, and it eliminates interference when access to the front of the chassis is necessary for maintenance and reading the LEDs.
A line card cable-management bracket attaches to each line card with captive screws. Cable ties on the bracket hold the network interface cables in place, keep the cables organized relative to their assigned connectors, and manage the bend radius of each cable as it enters the connector on the line card.
On line cards with multiple ports, the line card cable-management bracket keeps the network interface cables organized when your remove and replace the line card. You can unplug the network interface cables from their connectors on the line cards and leave the cables bundled in the line card cable-management bracket while you remove the bracket from the line card. That way, when you replace the line card, the network interface cables are already aligned with the correct line card cable connectors.
