Power Options

Power Considerations

Voltage in the range of 10–36 VDC or 8–24 VAC must deliver current commensurate

with power consumption. Recommended size for solid power conductors is 16–22 AWG;

for stranded conductors, use 16–18 AWG. Common is directly connected to zero volts

and chassis is isolated from zero volts. Input connections are reverse-polarity protected.

LED Indicators

The "PWR" LED glows solid green when the switch is properly powered. To aid in

troubleshooting, each copper port has two LEDs. The Port 1 LED labelled "L" glows

solid if a link exists, flashes to show activity and shows data rate by colour: green for

100 Mbps and yellow for 10 Mbps. The LED labelled "D" glows solid green if full-duplex

is on or is unlit when the port is in half-duplex mode — but in half-duplex operation it

will flash if a collision occurs. The LEDs of Ports 2–6 are unlabeled but work the same.

The fibre port (7 and 8) LEDs glow solid green if linked to a working 100BASE-FX port

and each LED flashes when data moves through the port.

Network Connections
