Installation
Connect the cables.
Refer to the following figure to perform these steps.
1.
Connect the cable from the power supply to the 7-pin power connector
on the DECrepeater 90C. Align the power symbol on the dc power
connector with the power symbol on the DECrepeater 90C and push
straight in.
2.
Connect the DECrepeater 90C to the power supply.
•
For a 240-volt power outlet, connect the power supply cord to
the modular power supply. Then plug the other end of the power
supply cord into the 240-volt power outlet.
•
For a 120-volt power outlet, plug the modular power supply
directly into the 120-volt outlet.
3.
All the LED indicators should turn on during initial power-up. After
approximately 0.5 seconds, the network activity LED should turn off
while the other LEDs remain on.
4.
Connect the Ethernet ThinWire T-connector to the port 0 BNC
network connector. Terminate the connection with a 50-ohm
terminator or extend the Ethernet segment to the next device.
5.
The port 0 status activity LED should be on or flashing to indicate the
amount of network traffic. The LED intensity varies.
6.
Connect ThinWire Ethernet cables to ports 1 through 6. Do not use
T-connectors. These ports have built-in terminators.
Install and verify devices.
1.
Connect devices to ports 1 through 6, using correctly terminated
ThinWire segments.
A port LED should turn on when the port is correctly terminated and
first receives network activity.
