Cooling
Requirements
Cooling air is drawn into the chassis by four fans mounted near the
rear of the chassis, venting exhausted air through the front of the
switch.
Do not block the front or rear air vents. The switch must have free access to
ambient air for cooling.
Power Requirements
Switch power connection is via switched connectors on the switch’s
front panel, as shown in Figure 2-1. The switch power requirements
are:
• Properly wired, earth-grounded outlet
• Input voltage: 85 – 265 VAC
• Total power: Up to 155 watts (depending on configuration, see
Appendix A, Specifications)
• Input line frequency: Nominally 47 to 63 Hz
The switch has an autoranging power supply that automatically
accepts voltages and line frequencies within its range. A green power
on indicator light is above the power switch.
Figure 2-1 Model DS-16B with Two Power Supplies
The switch meets IEC 801-5 surge voltage requirements, however, there is
no other provision for surge protection built into the switch’s power
supplies. An installation should include normal provisions to assure clean
power.
