Page 138: Mechanical Requirements
The distance between the mounting holes in the two posts must be 18.31 inches ±.063 inch, as specified in the EIA-310-D. Do not use an enclosed rack for ERX7xx models or the ERX310 router. It does not provide adequate ventilation. Copyright © 2010, Juniper Networks, Inc.
Page 139: Space Requirements
A fully loaded rack with three ERX14xx models must structurally support 300 pounds (136 kilograms). Optional mounting kits are available for 19-inch and 23-inch rack mounting (mid-chassis and front-chassis mounting). Contact your Juniper Networks sales representative for more information. Space Requirements If you use an enclosed rack for an ERX14xx model, ensure that there is a minimum of 3 inches of clearance between the inner side wall and the router.
Page 140: Cabling Recommendations
Ensure that power cables deliver sufficient power to the system. Attach laser fiber connectors only to Class 1 laser devices in accordance with IEC 825-1, Safety of Laser Products - Part 1. Route cables so that they do not restrict ventilation or airflow. Copyright © 2010, Juniper Networks, Inc.
