In the unlikely event your switch does not operate properly, follow the troubleshooting tips below. If you still
need help, contact Asanté’s technical support.
Problem Possible Solutions
The Power LED is not lit.
The Emergency Power LED is not lit. LED will turn off during system initialization. Check
your power connection. Plug the power cord into
another known working AC outlet.
The primary power supply has failed. Install the
optional emergency power supply and have the
primary power supply serviced as soon as possible.
This is normal. The emergency power supply LED will
only light if the primary power supply fails and the unit
takes over powering the switch.
The 10/100/1000 port Link LEDs are not lit. Check your 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 your 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 you are using the correct
cable type. 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 is
correct
• Make sure the switch port and the device
both are 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).
