Chapter 2 Installation Using the Router LEDs to Check Links Using the Router LEDs to Check Links Use the LEDs on the front of the router to check the links between the router and attached Ethernet devices or telephones. Use Table 2-5 to verify the link status of devices attached to Cisco 827, Cisco 827-4V, and SOHO 77 routers.
