A total of three connections must be made on the front panel when
connecting the line card to the network. Make sure that all cards are
firmly secured to the chassis before making network connections.
•
Connect to the MAIN port.
The Radiance redundant interface line card provides one
shielded RJ-45 jack for 10BASE-T connections and supports a
maximum segment length of 100 meters over Category 3, 4 or
5 twisted-pair cable.
Refer to STEP 3 for MDI-
II
to MDI-X switch functionality.
Before making the proper twisted-pair connection, verify the
port configuration of the connected device.
If you do not know the internal wiring configuration of the
other device’s RJ-45 port, consult the product documentation.
