Connecting Network Devices
Connecting to Network Device Console Ports
When connecting network device console ports, the type of device will determine the type of
cable required.
Console Port
Cable
RJ45 Cisco DTE
Straight Ethernet Cable
RJ45 Cisco DCE
Rollover Cable
Additional adapters may be required when connecting to console ports that use DB9 or
DB25 connectors or RJ45 ports with alternate pinouts.
Connecting To Power Ports
Mains Input Port
The mains power input port is the source of power to both of the USR4204 power out ports.
Connect an IEC C13 power cord with an 8A or better rating to this input. Connect the other
end of the power cord to the AC mains power service outlet.
WARNING: For continued protection against fire, replace the line fuse
only with a fuse of the same voltage, current rating, and type.
Power Out Ports
The power out ports provide power to attached equipment, and provide a means to measure
the load current of each output port and to remove power from each port. Connect IEC C14
power cords with an 8A or better rating to these outputs. Connect the other end of the
power cords to the equipment.
WARNING: The combined power requirement of the equipment
connected to all the USR4204 outputs must not exceed the USR4204
maximum input rating of 8 Amps.
The power from these ports is 'on' by default, even when the USR4204 is unpowered. When
a power port is switched 'off', both the LINE and NEUTRAL conductors are opened. If the
USR4204 loses power while a port is 'off ', the port will turn 'on', but when power is restored
to the USR4204, the port will return to the 'off' state.
The AC current being sourced from each of the output ports is monitored by the USR4204
and the RMS value is displayed on the Main Menu. To update the value, refresh the Main
Menu by hitting the spacebar, Enter key or using the Menu command ('-' default).
