Cisco 10008 Router Hardware Installation Guide

Chapter 2 Preparing for Installation
Site Planning
The electromagnetic pulse (EMP) generated by lightning or other high-energy phenomena can couple
enough energy into unshielded conductors to damage or destroy electronic equipment. If you have
previously experienced such problems, you should consult with RFI/EMI experts to ensure that you have
adequate electrical surge suppression and shielding of signal cables in your Cisco 10008 series router
operating environment.
Rack-Mounting and Location Guidelines
You can mount the Cisco 10008 router on an equipment shelf or tabletop. However, we recommend
rack-mounting the Cisco 10008 router. The rack-mounting hardware included with chassis is suitable
for most 19-inch equipment racks and telco-type racks.
The sections that follow describe criteria for selecting a rack to mount the Cisco 10008 series router, and
guidelines for placing the rack for reliable operation.
Rack Selection Guidelines
We recommend that you mount the Cisco 10008 router in an equipment rack, and includes the necessary
rack-mounting hardware which is suitable for most 19-inch equipment and telco-type racks.
Consider installing the Cisco 10008 router in a rack with the following features:
• NEBS compliant, 19-inch (48.3 cm) wide rack; or NEBS compliant 23-inch (58.4 cm) wide rack.
• EIA or ETSI hole patterns in the mounting rails. Required mounting hardware (screws, clip nuts,
and dress washers) is shipped with the Cisco 10008 series router. If the rack that you plan to install
the system in has metric-threaded rails, you must provide your own metric mounting hardware.
• Perforated top and open bottom for ventilation to prevent overheating.
• Leveling feet for stability.
Rack Configuration Guidelines
Several rack-mounting configurations are possible to provide maximum density. The following sections
describe mounting configurations for the Cisco 10008 chassis.
A standard 7-foot-high rack can accommodate three Cisco 10008 chassis mounted from the front. The
Cisco 10008 chassis can be flush mounted, with the front of the chassis being flush with the rack’s
mounting rails, or mid-mounted to bring the front of the chassis half-way out from the mounting rails.
Bracket extenders are required to mid-mount the Cisco 10008 chassis in a 23-inch telco rack. For more
information on mid-mounting, see Chapter 3, “Installing the Cisco 10008 Router.”
You can double the port density of a 7 ft. rack by installing six Cisco 10008 chassis back-to-back using
three High-Density Rack Kits (available from Cisco). Each kit includes all the necessary hardware to
mount one pair of back-to-back 10008 chassis on a sliding tray that allows access to the rear of the
chassis. The kit also includes a baffle kit to control the flow of exhaust air. The High-Density Rack Kit
can only be used with racks with the features described below:
• A rack with 3-inch or 6-inch U-channel
• A four-post cabinet rack with front and rear RETMA rails installed
