Installing a Cisco 12008 3-11
Rack-Mounting the Cisco 12008
If you intend to use your router with a single power supply of eith er type, the powe r supply
blank must remain in place at all times for EMI compliance and to ensure that cooling air
flows properly through the router.
Rack-Mounting the Cisco 12008
This section presents the procedures for mounting the Cisco12008 in a rack.
For the purposes of this procedure, it is assumed that you have installed the two mounting
brackets in a telco-style rack at the desired height in preparation for installing the router (see
the earlier section entitled “Installing the Mounting Brackets”). It is also assumed that you
have removed the power supplies and all of the components in the upper card cage to
minimize the weight of the router.
Caution The Cisco 12008, including the backplane, the power supply fan trays, and the
SFCs (if installed), weighs approximately 75 pounds (34.1 kg). For safety, a minimum of
two people should install the router in the rack. To prevent injury when lifting the router,
keep your back straight and lift with your legs.
To remove the router from the shipping pallet and mount it in a rack, perform the follo wing
steps:
Step1 Remove the four lag screws and retainer clips that secure the router to the
shipping pallet.
Step2 Affix the two lifting handles provided in the accessories box to the sides of the
router enclosure, as shown in Figure3-4.
Step3 With one person standing at either side of the router, grasp the lifting handle
affixed to the side of the router and lift the router off the shipping pallet.
Step4 With the assistance of a third person, position the router in the rack. Temporarily
rest the weight of the router on the mounting brackets (see Figure3-5).
