Ethernet Module LEDs
Every SmartBits Ethernet module has its own LEDs, which are located on the left side of
each module’s front panel (see Figure 3-4). Although the LEDs are similar for all
modules, some vary according to the features of each module. Ethernet module LEDs are
described in Table 3-4.

Note: Ethernet modules are listed in Table 1-3 on page 18. For complete descriptions of
the Ethernet modules, refer to the SmartBits System Reference manual.
