Connecting to the Ethernet 10/100 Module

To connect to the PCI Ethernet port on the Ethernet 10/100 module, run a cable
from the port to the LAN. The appropriate LNK LED (100 LNK or 10 LNK LED,
depending on the speed for which the port is configured) 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.
Ethernet PCI Port LEDs In addition to the common LEDs described earlier in
this chapter, the following LEDs indicate the status of the Ethernet 10/100BASE-T
port. (See Figure 32.)
ACT — Indicates that there is traffic on the PCI Ethernet port. If this LED is off,
then no data is currently being received or transmitted on the port.
10 LNK — Indicates a valid 10 Mbps link has been established.
100 LNK — Indicates a valid 100 Mbps link has been established.
If neither the 10 LNK nor the 100 LNK LED is on, a valid link could not be
established.
