Power Considerations

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

with 10-watt power consumption. The recommended size for solid power conductors is

16–22 AWG; for stranded conductors, use 16–18 AWG. Ground is directly connected

to zero volts and the chassis is isolated from zero volts. Input connections are reverse-

polarity protected.

Network Connections

The switch employs Auto-MDIX technology so that either straight-through or crossover

cables can be used to connect to network interface adapters or to another hub.

LED Indicators

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

troubleshooting, each port has two LEDs. The Port 2 LED labeled "L" glows solid if a

link

exists,

flashes

show activity and shows

data rate by color: green

for 100 Mbps and yellow

for 10 Mbps.

The LED

labeled "D" glows solid

green if full-duplex is on

or is unlit when that port is

operating in half-duplex

mode — but in half-duplex

operation it will flash if a

collision occurs. The other

port LEDs are unlabeled

but work the same.
