Link and Select LEDs
Each of the RJ-45 connectors on the 10BASE-T and 100BASE-TX
ports has dual integrated LEDs. The left LED displays the port’s
Link status. If this LED is lit (green), it indicates that the con-
nection between the port and the attached device is good. The
right LED, when lit (yellow), indicates that the full status of the
port (Receive, Collision, Full Duplex and 100 Mbps data rate) is
displayed by the shared vertical LED array (see “Shared Vertical
LED Array and Port Select Button” on the next page).

The 100BASE-FX ports have individual Link and Select LEDs that
perform the same functions.

Note:
The Link LEDs on unconnected ports will blink approximately
once every 5 seconds. This blinking reflects background diagnostics
run automatically by the switch and is not indicative of any error.
