3.2.1 9100-300 10/100BASE-TX Module
This module is a plug-in, which contains the 10/100BASE-TX interface, see Figure 3-5.
Caution: To protect the Ethernet port from an intrabuilding lightening surge, use a properly grounded
shielded cable.
Figure 3-5. 10/100BASE TX Interface Module.
This interface provides 10 and 100Mbps operation, using UTP cables. The interface components are the
following:
•
RJ-45 shielded connector
•
Port LEDs
•
Tx Transmit (Green)
• Lnk Link (Green)
• Col Collision (Yellow)
• Fdx Half/Full-Duplex (Green)
• Rx Receive (Green)
• Aut Auto negotiation enabled (Green)
• Par Partition/Disable (Red)
• 100 100Mbps indication (Green)
•
Connectors: Edge connector to the main board unit
•
UTP Crossover Switch
The 10/100BASE TX interface modules can be configured to connect to either standard DTE devices, or to
repeaters, which usually cross their XMT and RCV pairs internally, without the need for special crossover
cables.
To connect the 10/100BASE TX interface modules to a standard DTE device with a standard straight-
through cable, set the Normal/Crossover switch, which is internally crossed, to the X position, switch
button OUT, shown in Figure 3-5.
To connect the 10/100BASE TX interface modules port marked with an X, as with most repeaters with a
standard straight-through cable, set the Normal/Crossover switch to the N position, switch button N, shown
in Figure 3-5.
Set the interface to 10 BASE -TX or 100 BASE-TX in software. For details, see Chapter 5.
