AT-x230-10GP and AT-x230-18GP Switches Installation Guide

Problem 5: Network performance between a twisted pair port on the

switch and a network device is slow.

Solution: There might be a duplex mode mismatch between the port and

the network device. This occurs when a twisted pair port using Auto-

Negotiation is connected to a device with a fixed duplex mode of full

duplex. If this is the cause of the problem, adjust the duplex mode of the

port on the network device or on the switch so that both ports are using the

same duplex mode.

Problem 6: A port’s Link/Activity/Speed LED is blinking.

Solutions: The link between the port and the network device is intermittent.

Try the following:

 Connect another network device with a different cable to the port. If

the Link LED remains steady on, then the problem is with the

original cable or the network device.

 If the problem is with an SFP transceiver, check that the

transceiver is fully inserted in the slot.
