Connecting to the Network

Connecting to the Network
This section provides the procedures for connecting Category 5 unshielded twisted pair (UTP)
segments or SFP and SFP+ pluggable transceivers from the network or other devices to the SSA.

Connecting Category 5 UTP Ethernet Cables to the RJ45 Ports

The fixed RJ45 front panel connections of the SSA‐T4068‐0252 and SSA‐T1068‐0652 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.
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 it is on:
a.
b. Verify that the device at the other end of the twisted pair segment is on and properly
c.
If a link is not established, refer to Chapter
4. Repeat steps 1–3, until all connections have been made.
2-16 Installation
Note: If the SSA is being installed in a network using Link Aggregation, there are rules concerning
the network cable and port configurations that must be followed for Link Aggregation to operate
properly. Before connecting the cables, refer to the Enterasys S-Series Configuration Guide for the
configuration information. For details on how to obtain manuals, refer to
page xvi.
Note: All RJ45 front panel ports on the SSA-T4068-0252
Unshielded Twisted Pair (UTP) cabling with an impedance between 85 and 111 ohms. You can use
Category 3 cable only for 10 Mbps connections.
Verify that cabling is 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.
connected to the segment.
Verify that the RJ45 connectors on the twisted pair segment have the proper pinouts and
check the cable for continuity.
