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

Connecting to the Ethernet Port

To connect to the Ethernet 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 10BaseT. This
cable length should include service loops at the ends and the complete cable route
distances.
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 21.
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 exisits with the remote link. For example, the Ethernet cable
may not be connected properly, or the remote Ethernet unit may be down.
