Chapter 2 Preparing for Router Installation

General Site Requirements

Caution For the safety of your equipment, periodically check the resistance value of the antistatic strap. It should be between 1 and 10 megohms (Mohm).

General Site Requirements

This section describes the requirements your site must meet for safe installation and operation of your router. Ensure that the site is properly prepared before beginning installation. If you are experiencing shutdowns or unusually high errors with your existing equipment, this section can also help you isolate the cause of failures and prevent future problems.

Rack Requirements

The following information will help you plan your equipment rack configuration:

•Allow clearance around the rack for maintenance.

•Allow at least one rack unit of vertical space between routers.

•Enclosed racks must have adequate ventilation. Ensure that the rack is not congested, because each router generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air. Heat generated by equipment near the bottom of the rack can be drawn upward into the intake ports of the equipment above.

Router Environmental Requirements

Mount the Cisco CGR 2010 routers in a rack. The location of your router and the layout of your equipment rack or wiring room are extremely important considerations for proper operation. Equipment placed too close together, inadequate ventilation, and inaccessible panels can cause malfunctions and shutdowns, and can make maintenance difficult. Plan for access to both power supply side and cable side panels of the router.

Note Allow at least one rack unit of vertical space above the router.

When planning your site layout and equipment locations, refer to the “General Site Requirements” section on page 2-4, section. If you are currently experiencing shutdowns or an unusually high number of errors with your existing equipment, these precautions and recommendations may help you isolate the cause of failure and prevent future problems.

•Ensure that the room where your router operates has adequate air circulation. Electrical equipment generates heat. Without adequate air circulation, ambient air temperature may not cool equipment to acceptable operating temperatures.

•Always follow ESD-prevention procedures described in the “Preventing Electrostatic Discharge Damage” section on page 2-3to avoid damage to equipment. Damage from static discharge can cause immediate or intermittent equipment failure.

•Ensure that the chassis cover and module cable side panels are secure. All empty interface card slots and power supply bays must have filler panels installed.
