Connecting To The Ethernet 10Base-T Port - 3Com SuperStack II PathBuilder S330 Reference Manual

Connecting to the Ethernet 10BASE-T Port

To connect to the standard Ethernet 10BASE-T port, run a cable from the port to
the LAN. The Link LED illuminates if you make the connection properly. The cable
run from the PathBuilder S330/S310 Ethernet port to the Ethernet LAN connection
must be no longer than 100 meters, in compliance with EIA/TIA standards for
10BASE-T. This cable length should include service loops at the ends and the
complete cable route distances.
For connector pinouts, see "Ethernet Interface (10BASE-T and 10/100BASE-T)
Connector Pinouts" in Appendix A.
Ethernet Port LEDs In addition to the common LEDs described earlier in this
chapter, the following LEDs indicate the status of the Ethernet port. (See
Figure 26.)
TX data (green) — Indicates transmit (to the cable) activity. The LED flashes
momentarily for each frame sent to the cable.
RX data (green) — Indicates receive (from the cable) activity. The LED flashes
momentarily for each frame received from the cable.
Link (green) — Indicates that you have a link to the remote system. If this LED
is off, then a problem exists with the remote link. For example, the Ethernet
cable may not be connected properly, or the remote Ethernet unit may be
down.
