twisted pair connections while ports 3, 4, 5, and 7 are shielded twisted pair
connections.
In addition to complying with the 10BASE-T standard, each port provides
support for features that are beyond the scope of the 10BASE-T standard:
❑ supports shielded twisted pair cable
❑ allows Low Squelch level (which significantly increases achievable link
distances)
❑ allows Link Integrity to be disabled (which allows connection to some
equipment which does not conform to the 10BASE-T standard)
Before installing the Ethernet 10BASE-T Module, read the ONline System
Concentrator Installation and Operation Guide.
Indicators
The 10BASE-T Module has eight Activity and eight Status LEDs on the front
panel that indicate the state of each port on the module. Figure 1-1 shows
the locations of these indicators and Table 1-1 describes how to read them.
