– Not affected. The LED continues to operate as other conditions dictate. 1 RDY blinks for a duplicate IP on any network, and the individual NS LEDs indicate the network with the duplicate IP. 2 RDY blinks for a default IP on any network. 3 RDY blinks 5 if any network is configured to be used, but no Ethernet link is connected to it. For example, the router is enabled but ETH 2 does not have a cable connected to it. 4 ACT remains ON after the module has completed its power-up sequence and has an active connection to the CPU.
