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

 The default speed setting for the ports is Auto-Negotiation. This

setting is appropriate for ports connected to network devices that

also support Auto-Negotiation.

 The default speed setting of Auto-Negotiation is not appropriate for

ports connected to 10BASE-T and 100BASE-TX network devices

that do not support Auto-Negotiation and have fixed speeds. For

those switch ports, you should disable Auto-Negotiation and set

the port’s speed manually to match the speeds of the network

devices.

 The 10/1000BASE-T and 100BASE-TX ports must be set to Auto-

Negotiation, the default setting, to operate at 1000Mbps.

 The default duplex mode setting for the ports is Auto-Negotiation.

This setting is appropriate for ports connected to network devices

that also support Auto-Negotiation for duplex modes.

 The default duplex mode setting for the ports is Auto-Negotiation.

This setting is appropriate for ports connected to network devices

that also support Auto-Negotiation for duplex modes.

 The default duplex mode setting of Auto-Negotiation is not

appropriate for ports connected to network devices that do not

support Auto-Negotiation and have a fixed duplex mode. You

should disable Auto-Negotiation on those ports and set their duplex

modes manually to avoid the possibility of duplex mode

mismatches. A switch port using Auto-Negotiation defaults to half-

duplex if it detects that the end node is not using Auto-Negotiation,

which can result in a mismatch if the end node is operating at a

fixed duplex mode of full-duplex.

 Do not attach cables to ports of static or LACP port trunks until

after you have configured the trunks on the switch. Otherwise, the

ports will form network loops that can adversely affect network

performance
