Question about HP ProCurve 2626 (J4900B) 24x10/100 Mbps Networking Switch
We have two HP 2626 connected back to back via media convertors across fiber between buildings. We are having dropouts every month or two and they always last really close to two minutes. Is there a way we can confirm that its not an issue with the switches? When we lose the connection, the "send" switch shows these errors: "Half Duplex Mismatch" and "Excessive late collisions". The "receive" switch shows "Excessive CRC/alignment errors" The fiber has been throughly cleaned and tested. The media convertors as well as the patch cables have been replaced. There is only one main signal going through the switches plus a serial to ethernet convertor that transmits a very small amount of data. Any assistance would be appreciated.
For uplinks and backbone, make sure you set the speed and duplex and do not leave it to auto configure

Have you tried to telnet into your device and turn up the logging? Also, have you confirmed at what duplex you are running on the ports that the actual connection is coming in on? Is there a firewall connected to your switches? If so, have you checked the NIC cards to make sure they are functioning appropiately? Check out your DMZ card to see if that is causing any issues.
