Rack Specifications and Recommendations

The SFS 7024 switch is designed to be installed in an existing 19-inch equipment rack or server rack.

The SFS 7024 switch is designed for a four-post server cabinet. It is not designed for a two-post telco cabinet.

Racks should conform to conventional standards. In the United States, use American National Standards Institute (ANSI)/Electronic Industries Association (EIA) standard ANSI/EIA-310-D-92, and International Electrotechnical Commission (IEC) 297

•Racks should meet the following mechanical recommendations:

–Four-post, 19" rack to facilitate easy maintenance

–Universal mounting rail hole pattern identified in IEC Standard 297

–Mounting holes flush with the rails to accommodate the switch

•Use a rack grounding kit and a ground conductor that is carried back to earth or to another suitable building ground. Ground the equipment rack to earth ground.

•Provide enough room to work on the equipment. Clear the work site of any unnecessary materials. Make sure the equipment will have enough clearance for front and rear access.

Installing and Routing Cable

Note Building and electrical codes vary depending on the location. Comply with all code specifications when planning the site and installing cable.

When running cables to the equipment, consider the following:

•Do not run cables where they can be stepped on or rolled over.

•Be sure cables are intact with no cuts, bends, or nicks.

•Provide proper strain relief for standard IB cables by adhering to the following guidelines:

Figure 2-2 Cable Bend Radii

Assembly 90-Degree Bend Radii

American Wire Gauge (AWG) Size	4X Bend Radius
Cable

24	5.20 inches

26	4.80 inches

28	4.70 inches

•Temporary 90-degree bend can never be more than 0.5 inches tighter than the values listed above for any assembly.

•This is the absolute minimum sustained bend radius for each 4X cable AWG size. This measurement is the distance from the panel to the point where the cable makes a 90-degree bend. In other words, this number includes the 2" connector stand-off from the panel surface.
