connected to that port is introducing an excessive amount of broadcast frames to the network. Some pieces

of network equipment operate by sending out broadcast frames regularly.
Refer to the documentation that accompanies the switch for information on disabling the broadcast
operation.
If the problem persists and the unit still does not operate successfully, contact your HP network supplier with

the following information before returning the unit:



Product number and serial number (printed on a label supplied with the unit).



A brief description of the issue.
