Installing a Router
This section explains the procedures for installing Cisco 12006 and Cisco 12406
Routers and contains the following sections:
• Installing the Rack-Mount Brackets (Optional), page 3-3
• Installing the Chassis in a Rack, page 3-7
• Installing Center-Mount Brackets (Optional), page 3-5

Before installing Cisco 12006 and Cisco 12406 Routers, see Chapter 2,
“Preparing for Installation,” for information on environmental considerations and
requirements.
Ensure the following before you install the router:
• The exhaust vents on the blower module mounted at the rear of the chassis are
not blocked.
• The air filter is mounted on the right side as you face the router; air flow to
the blower module is not blocked.
• There is 24 inches (61 cm) of clearance at the rear of the chassis so you can
read the blower module LEDs and perform maintenance on the module.
• There is 24 inches (61 cm) of clearance in front of the router chassis to enable
working with line cards and power supplies, and attaching Network Interface
Cable (NICs) or other components.
• Location is temperature controlled, air conditioned, and dust free.
• Power cables and power supplies have been checked for compatibility with
your power service.
• Labels on the equipment have been checked to ensure that the power service
at your site is suitable for the router.
• AC power source receptacles are easy to reach.
Warning
Do not mix power module input types in the router. All power modules installed
in a router must be either AC-input power supplies or DC-input PEMs.
