Removing and Installing the Chassis

Instructions for removing a defective Cisco 12006 or Cisco 12406 Router chassis and installing a replacement chassis are presented in the following sections.

The replacement chassis is an integrated, sheet-metal assembly that includes the following items:

•Six-slot RP and line card cage

•Two-slot clock and scheduler card cage

•Three-slot switch fabric card cage

•Two alarm card slots

•Two air filters

•Two power module bays

•One backplane with connectors

The chassis can be rack mounted or placed on a stable flat surface.

Tools and Equipment

You need the following items to replace a router chassis:

•ESD-preventive strap

•3/16-inch and 1/4-inch flat-blade screwdrivers

•Number 1 and Number 2 Phillips screwdrivers

•9/16-inch (14-mm) wrench

•3/4-inch (19-mm) socket and ratchet wrench

•Vacuum cleaner

•Antistatic bag or similar ESD-preventive container

•Replacement chassis, Part Number: GSR6/120=
