Power Options
Power Considerations
Voltage in the specified range must deliver current commensurate with 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 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 that port is operating in half-duplex mode
— but in half-duplex operation it
will flash if a collision occurs. The LEDs of Ports 2
–5 are unlabeled but work the same.
