Possible Solutions

The Power LED is not lit.

Check the power connection. Plug the power cord into another known working AC outlet.

The primary power supply has failed. Install the optional external power supply and have the primary power supply serviced as soon as possible.

The System LED is amber.

The switch detects a hardware malfunction. Check the temperature of the room, listen for the fan or the electrical connection.

The External Power LED is not lit.

The external power supply is not installed properly or has failed. Contact Asante immediately for a replacement.

The 10/100/1000 port Link LEDs are not lit.

Check the cable connections. Make sure the connectors are seated correctly in each port, and that the correct type of cable is used in each port. See Chapter 2.6: Connecting to the Network for more information.

The GBIC Link LED is not lit.

Check the GBIC connector. Make sure the cables are inserted correctly, with the Transmit (Tx) connector on one side of the link connected to the Receive (Rx) connector on the other side of the link.

Cannot establish communication to another device (switch, router, workstation, etc.).

•Make sure the Link LED for the port in use is on. Make sure the correct cable type is used. See Chapter 2.6 Connecting to the Network for more information on cabling procedures

•Make sure the IP address, subnet mask, and VLAN membership of the switch are correct

•Make sure the switch port and the device are both in the same VLAN

•Try to connect to a different port

Cannot auto-negotiate the port speed.

Make sure that auto-negotiation is supported and enabled on both sides of the link (in both devices).
