Cisco Systems Cisco 12008 manual Installing the Mounting Brackets

Installing the Mounting Brackets

You must allow at least 24 inches (61 cm) of clearance in front of the router enclosure for installing or replacing line cards, fan trays, and power supplies, and for attaching network interface cables or equipment.

Caution You cannot use an AC-input power supply and a DC-input power supply in the same router. All power supplies installed in a router must be of the same type. Do not attempt to install an AC-input power supply in a router with a DC-input power supply, or vice versa.

Installing the Mounting Brackets

Mounting brackets are shipped with every Cisco 12008 as part of an accessory kit. These mounting brackets are designed for use with either a telco-style (2-post) or a 4-post equipment rack. For simplicity, the procedure in this section describes the use of the mounting brackets in conjunction with a telco-style rack.

Use of the mounting brackets is optional; you can install the Cisco 12008 in the rack without using these brackets. However, due to the size and weight of the router, it is recommended that these brackets not only be used, but also that two or more people install the router to minimize the risk of personal injury or damage to the equipment.

Note The mounting brackets temporarily bear the weight of the router while it is being positioned in the rack for permanent installation. These brackets can be left in place following router installation.

To prepare for router installation, you can install the mounting brackets directly opposite each other in the rack at any desired height. The height chosen should take into account the following factors:

•

•

•

The network cabling and equipment installation requirements

Whether or not other equipment is (or will be) installed in the rack

Whether or not more than one router will be installed in the rack
