SIC-1GEC 43

c CAUTION: SIC-1GEC uses COMBO interface; therefore it cannot support fiber and

electrical interfaces at the same time. When the router is powered on, the electrical interface takes effect by default. If you want to use a fiber interface, use a command to configure it.

Interface LEDs The following figure illustrates the SIC-1GEC panel.
