Interpreting Control Module LEDs
Control modules have the following LEDs:
•
On the left side of each control module, three LEDs enable you to determine
the control module status and whether the control module is active or
secondary. See Figure 3-1.
•
Each Ethernet port has two LEDs that show the network interface status. See
Figure 3-1.
Control module LEDs are described in Table 3-1. Ethernet port LEDs are
described in Table 3-2.
