Troubleshooting

➌

The network

connection is not

working properly.

Try the following procedures:

• For the indicated port, verify both ends of the cabling, at the switch and the

connected device, are securely connected.

• Verify the connected device and switch are both powered on and operating

correctly.

• Verify you have used the correct cable type for the connection. See

“Connecting the Network Cables” on

page 9 for the correct cable

specifications.

– for fiber-optic connections, verify the transmit port on the switch is

connected to the receive port on the connected device, and the switch

receive port is connected to the transmit port on the connected device.

• Verify the port has not been disabled through a switch configuration change.

You can use the console interface, or, if you have configured an IP address

on the switch, use the web browser interface, or ProCurve Manager network

management software to determine the state of the port and re-enable the

port if necessary.

• Verify the switch port configuration matches the configuration of the

connected device. For example, if the switch port is configured as “Auto”, the

port on the connected device also MUST be configured as “Auto”. If the

configurations don’t match, the results could be a very unreliable connection

or no link at all.

• If the other procedures don’t resolve the problem, try using a different port or

a different cable.

module has a power

failure

Try re-seating the module and rebooting the switch. If this does not clear the

error call your ProCurve authorized LAN dealer, or use the electronic support

services from ProCurve to get assistance. See the Customer Support/Warranty

booklet for more information.
