Preparing for Installation SmartStack STS16-20D/STS16-20R Token Ring Switches Installation and User Guide
Site Requirements
Following are the site requirements for installation.
Environment
Choose a clean, dust-free, preferably air-conditioned location. Avoid direct
sunlight, heat sources, or areas with high levels of EMI (Electromagnetic
Interference).
Chassis Accessibility
Make sure the front and back panel of the equipment is accessible so that you can
monitor the LED indicators and access the control switches. Leaving enough
clearance at the front and back will also allow easier cabling and service.
Cooling and Airflow
Two fans, which are located at the left side of the switch, cool the interior by
drawing air through vents on the left side and forcing heated air out through holes
in the right side. If the internal temperature exceeds 50°C (112°F), a temperature
error is reported to the console.
➽ Caution: To protect the equipment from overheating, do not operate it in an area
that exceeds the maximum recommended ambient temperature of 40°C (104°F). To
prevent airflow restriction, you must allow at least 7.6 cm (3") of clearance around
chassis openings for proper airflow.
Power
The source electrical outlet should be installed near the switch, be easily accessible,
and be properly grounded.
Also, observe the following power cable considerations before you start the
installation of the SmartStack STS16-20D Token Ring Switch and/or the
SmartStack STS16-20R Token Ring Switch.
11. The socket outlet shall be installed near the equipment and shall be easily
accessible.
12. To prevent electrical shock, the power cord set used must comply with national
regulations.
a. The female receptacle of the cord must meet CEE-22 requirements.
