Power Options
Power Considerations
Voltage in the range of 10
–36 VDC or 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. 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 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 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.
