Juniper MX104 Hardware Guide

Clearance Requirements for Airflow and Hardware Maintenance on MX104 Routers
When planning the installation site, allow sufficient clearance around the rack (see
Figure 19 on page 75):
•
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 side-cooled routers.
Allow 2.8 in. (7 cm) between the side of the chassis and any non-heat-producing
surface such as a wall.
•
For service personnel to remove and install hardware components, there must be
adequate space at the front and back of the router. At least 24 in. (61 cm) is required
both in front of and behind the router. NEBS GR-63 recommends that you allow at
least 30 in. (72.6 cm) in front of the rack and 24 in. (61.0 cm) behind the router.
