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. COM is directly connected to zero volts and the
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. The
behaviour of the ―STAT‖ LED is explained in the Software Manual. 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
as the Port 1 LED. The fibre port LEDs glow solid green when a link exists and flash to
show activity.
Reset Switch
If needed, you can reset factory default settings via a hole on bottom of the unit. Use a
paperclip or similar tool to press the recessed button for at least 3 seconds while the
unit is powered. Then release the button and remove power for 3 seconds. Restore
power and the unit will now use its default IP values and User ID and Password which
are both blank.
