Connecting Category 5 UTP Ethernet Cables to the RJ45 Ports

The fixed RJ45 front panel connections of the SSA-T4068-0252, SSA-T1068-0652, and SSA-T1068-0652A are 10/100/1000 Mbps ports. They have internal crossovers and support automatic-polarity sensing which eliminates the need for a crossover cable, regardless of whether the connection is to another network device or a workstation.

Note

All RJ45 front panel ports on the SSA-T4068-0252, SSA-T1068-0652, and SSA-T1068-0652A support Category 5 Unshielded Twisted Pair (UTP) cabling with an impedance between 85 and 111 ohms. You can use Category 3 cable only for 10 Mbps connections.

1. Ensure that the far-end device connected to the other end of the segment is powered on.
2. Connect the far-end device‘s twisted pair segment into the appropriate SSA RJ45 port connector.
3. Verify that a link exists by checking that the port RX (Receive) LED is on: flashing amber, blinking green, or solid green.
   If the RX LED is off and the TX (Transmit) LED is not blinking amber, perform the following steps until the RX LED is on:
   1. Verify that the proper cabling is being used: Category 5 UTP with an impedance between 85 and 111 ohms.
      If the port is to operate at 100 Mbps or 1000Mbps, you must use Category 5 cabling.
   2. Verify that the device at the other end of the twisted pair segment is on and is properly connected to the segment.
   3. Verify that the RJ45 connectors on the twisted pair segment have the proper pinouts.
   4. Check the cable for continuity.
      If a link is not established, refer to Troubleshooting for details.
4. Repeat step 1 through step 3 until all connections have been made.
