Preparing for Router Installation
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 63
■ Rack Requirements on page 64
■ Router Environmental Tolerances on page 66

■ Site Preparation Checklist on page 75
General Site Guidelines
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. Ensure that there is adequate circulation in the installation
location. In J2320 and J2350 routers, allow at least 6 in. (15.2 cm) of clearance
between the left and right sides of the chassis and adjacent equipment. In J4350
and J6350 routers, allow at least 6 in. (15.2 cm) of clearance between the front
and back of the chassis and adjacent equipment.
■ Follow ESD procedures described in “Preventing Electrostatic Discharge
Damage” on page 201, 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.
