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.
