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 2010 CGR 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
, 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
to 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.
