Verifying the Network Connections Are Working

Check the port LEDs for the newly-installed module to ensure the port(s)
connected in the preceding step are operating correctly. Each port on the
switch modules has Link and Mode LEDs near it as shown in the next
illustration.
Figure 11. Example: Link and Mode LEDs
The Link LED will be lit for each port that is connected properly to an
■
active network device.
If the Link LED does not go on when an active network cable is connected
to the port, there may be something wrong with the cable, the cable
connectors, or the device at the other end of the cable. See the
troubleshooting information on
■ If the switch Mode is set to display activity (the
is lit), then the Mode LED for each port that is transmitting and/or
receiving packets will flicker when traffic is detected on the port.
■ If the Mode is set to display full duplex (the
lit), then the Mode LED will be lit for each port that is operating in full
duplex. If the port is in AUTO, the duplex mode LED will be off.
If the Mode is set to display maximum link speed operation (the
■
indicator LED is lit), then the Mode LED will be lit for each port that is
operating at its maximum possible link speed:
• Off = 10 Mbps
• Flashing = 100 Mbps (the flashing behavior is a repeated on/off cycle
once every 0.5 sec.)
• On = 1000 Mbps
• If the port is in AUTO, the spd mode LED will be off.
