Removing the Front Covers from Cisco 12016 Original Series 
Routers
The chassis front covers for the power shelf and upper blower module, upper card 
cage, lower card cage, and lower blower module are fastened to the chassis by ball 
studs on the front of the chassis (
Note
The power shelf and upper blower module front cover is packaged in the 
accessory kit to permit the foam shipping cap to fit securely on the top of the 
router, and to protect the router without damaging the front cover.
To remove a cover, grasp the outside edges of the cover and pull it straight out to 
detach it from the front of the chassis.
