Preparing for Router Installation

General Site Guidelines

Before installing a J-series Services Router, make sure that your site has the proper
operating environment and equipment. Use the checklist at the end of the chapter
to help you prepare your site.
This chapter discusses the following topics:
General Site Guidelines on page 71
Rack Requirements on page 72
Router Environmental Tolerances on page 73
Fire Safety Requirements on page 73
Power Guidelines, Requirements, and Specifications on page 74
Network Cable Specifications on page 78
ISDN Provisioning on page 79
Site Preparation Checklist on page 79
The following precautions help you plan an acceptable operating environment for
your Services Router and avoid environmentally caused equipment failures:
For the cooling system to function properly, the airflow around the chassis
must be unrestricted. Allow at least 6 in. (15.2 cm) of clearance between the
front and back of the chassis and adjacent equipment. Ensure that there is
adequate circulation in the installation location.
Follow ESD procedures described in "Preventing Electrostatic Discharge
Damage" on page 205, to avoid damaging equipment. Static discharge can
cause components to fail completely or intermittently over time.
Install blank PIM panels in empty slots, to prevent any interruption or
reduction in the flow of air across internal components.
