The Cisco 7140-2E3 WAN ports have one enabled (EN) LED and six uplink port status LEDs (each port
has a set of status LEDs). After system initialization, the enabled LED goes on to indicate that the ports
have been enabled for operation. If the initialization fails for any reason, the enabled LED will not go
on. The LEDs are shown in
