Chassis Cable Management

Chassis Cable Management
The Cisco CRS 4-slot line card chassis has cable management features for the front (PLIM) side of the
chassis, just above the card cage. The horizontal cable management trays have a special telescoping
feature that allows them to be extended when the chassis is upgraded with higher-density cards. This
extension also helps when installing the cables in the chassis.
