B-2APPENDIX B: SITE REQUIREMENTS AND SAFETY CODES

Be sure that each wiring closet has a suitable ground. Ground all metal racks, enclosures, boxes, and raceways in the closet.

Use AC power, 15-ampere service receptacles, type N5/15 or NEMA 5-15R for 120 VAC, and the other system specifications shown in Appendix A.

Be especially sure to meet all system environmental requirements in Appendix A, such as ambient temperature and humidity.

Be sure that the ventilation in the wiring closet is adequate to maintain a temperature below 40 ˚C (104 ˚F).

Install a reliable air conditioning and ventilation system if you plan to have two or more Switch 3900 systems in a single wiring closet.

To prevent overheating during nonbusiness hours, guard against the ventilation being shut down while a Switch 3900 system remains powered up.

Distribution Rack Requirements

If you plan to mount your SuperStack II Switch 3900 systems in a distribution rack, verify that your rack meets the basic mechanical and space requirements described in this section.

Protective Grounding for the Rack

To ensure that voltages induced into wiring by lightning or other disturbances are directed to ground, ground your distribution racks properly. Use a distribution rack grounding kit and a ground conductor that is carried back to earth or to another suitable building ground. To order the grounding kit, contact your sales representative.

Space Requirements for the Rack

Provide enough space in front of and behind the system so that you can service it easily. Allow a minimum of 76 cm (30 in.) between the rack and any wall behind or in front of it. Extra room on each side is optional. See Figure B-1.

Install your distribution rack near an easily accessible power outlet. You can power down the system only by removing the power cord from the power source.
