Chapter 4: Preparing the Site for ACX1000 and ACX1100 Router Installation
When planning the installation site, allow sufficient clearance around the rack (see
15 on page 29):
For service personnel to remove and install hardware components, allow at least
2.16 in. (5.5 cm) in front of the router.
The rack or cabinet must have an adequate supply of cooling air.
Ensure that the cabinet allows the chassis hot exhaust air to exit from the cabinet
without recirculating into the router.
When deploying the router in harsh environments where the router may operate
between 131° F (55° C) and 149° F (65° C), allow a 1–rack unit (U) gap above and
below the router.
Minimum 1 meter/second airflow in any direction
