Configuring TCP/IP Settings Make Sure the Switch is Set to Autonegotiate Speed/Duplex Settings When the server is shipped from the factory, both ports are set to autonegotiate. This setting allows the Snap Server to base speed and duplex settings on the physical port connection to a switch. Thus, the switch/hub to which the Snap Server is cabled must be set to autonegotiate to initially connect to the server; otherwise, network throughput or connectivity to the server may be seriously impacted. Changing from Auto to a Fixed Setting You can configure a fixed setting on the Network > TCP/IP screen in the browserbased Administration Tool. If you change this setting, be sure to: 1) configure the fixed setting in the Administration Tool first; and second, (2) configure the switch to the same fixed setting. If you change the switch setting before you change the setting in the Administration Tool, the Snap Server may not connect to the network. The Link light on the front panel of the Snap Server will be off or amber if the server is not connected to the network. 16 Snap Server Administrator Guide

Snap Server Administrator Guide
Make Sure the Switch is Set to Autonegotiate Speed/Duplex Settings
When the server is shipped from the factory, both ports are set to autonegotiate.
This setting allows the Snap Server to base speed and duplex settings on the
physical port connection to a switch. Thus, the switch/hub to which the Snap
Server is cabled
must
be set to autonegotiate to initially connect to the server;
otherwise, network throughput or connectivity to the server may be seriously
impacted.
Changing from Auto to a Fixed Setting
You can configure a fixed setting on the
Network > TCP/IP
screen in the browser-
based Administration Tool. If you change this setting, be sure to: 1) configure the
fixed setting in the Administration Tool first; and second, (2) configure the switch to
the same fixed setting. If you change the switch setting before you change the
setting in the Administration Tool, the Snap Server may not connect to the network.
The Link light on the front panel of the Snap Server will be off or amber if the server
is not connected to the network.
