FE-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 4-2

and

Table 4-3

provide a functional description of the 10/100

LED when the RX LED is on or off, respectively.
