NETWORK LINK AND ACTIVITY INDICATION
For copper-wire Ethernet connections, the state of the network link and activity is indicated by the LEDs on the RJ-45
connector, as described in Table 1. For fiber optic Ethernet connections, the state of the network link and activity is indicated
by a single LED located adjacent to the port connector, as described in Table 2. Broadcom Advanced Control Suite 3 also
provides information about the status of the network link and activity (see Viewing Vital Signs).
