Cisco 7140 Series Overview
The Cisco 7140-8T WAN ports have one enabled (EN) LED and five status LEDs (each of the eight ports
has a set of status LEDs). After system initialization, the enabled LED goes on to indicate that all 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 Figure 1-24 and described in Table 1-8.
