Configuring TCP/IP Settings Connect the Snap Server to the Network via a Switch While it is possible to connect a Snap Server to the network via a hub, this configuration unduly restricts the performance of the server for the following reasons: • Hubs do not support full-duplex. You can employ full-duplex only when the Snap Server is connected to a switch. • Hubs do not support Gigabit speeds. Attempting to force a Gigabit setting when the Snap Server is cabled to a hub will produce unintended consequences. 100 Mps/half duplex is the best performance possible when connected to a hub. 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. Configure the Switch for Load Balancing If you select either the Switch Trunking or Link Aggregation network bonding configuration, be sure the switch is configured correctly for that bonding method. No switch configuration is required for Load Balancing (ALB). 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: • Configure the fixed setting in the Administration Tool first; and • 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. 24 Snap Server Administrator Guide
