4.2FE-100TX LED

The optional FE-100TX has one LED labeled 10/100. The 10/100 LED together with the receive LED allows the user to determine the link status and the operating speed of the Fast Ethernet Interface Module. The 10/100 LED and the Receive (RX) LED are shown in Figure 4-2.

Table 4-2and Table 4-3provide a functional description of the 10/100 LED when the RX LED is on or off, respectively.
