II Switch 3900 AFETY ODES The cabling system plan at your facility probably covers most wiring closet concerns. 3Com also recommends that you check these items: Verify that your wiring closet meets all of the requirements in your facility cabling plan.
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.
In countries other than the United States, comply with IEC Standard 297: Dimensions of Panels and Racks. In addition, 3Com recommends that your distribution racks meet these requirements: Use an open style, 19-inch rack. The rack styles shown in Figure B-2 facilitate easy maintenance and provide excellent ventilation.
