APPENDIX D Preparing Your Site
•Ensure that all IP environment requirements are met, such as Autonomous System (AS) number, port IP address and mask, management Ethernet port IP address and mask, and broadcast address.
Environmental Requirements
Choose a location for the system that is dry, relatively dust free, well ventilated, and air conditioned. If you install equipment in a rack, be sure that the floor is capable of supporting the combined weight of the rack and the installed equipment. Place the system in a location with sufficient access to power and network cables.
Like other network devices, the system generates a significant amount of heat. It is important to provide a balanced environment so that the system performs properly and safely. See Appendix A, System Specifications for acceptable ranges of temperature and humidity.
Be sure to allow enough space around the system for adequate ventilation. Inadequate ventilation can cause the system to overheat. See Appendix A, System Specifications and Chapter 2, Installing the ERX System for details about space requirements.
Caution: Do not block the air vents on the ERX system. Otherwise, the system may overheat.
Safety Guidelines
For your safety, before installing the system, review all safety warnings specified in this section.
Temperature Warning: The recommended maximum ambient temperature is 50° C (122° F). The internal temperature of the rack should be considered for safe operation.
Rack Installation Warning: Install equipment in the rack from the bottom upward. This will maintain the stability of the rack and reduce the chance of the rack’s tipping over.
Heavy Equipment Warning: Two people are required to lift an ERX system. Three people are required to install an ERX system in a rack. The equipment is extremely heavy.
Ground (Earth) Warning: Connect the ERX system or rack to ground (earth), and ensure that a reliable grounding path is maintained in the rack.
