选择适当的介质、线缆、端口和连接头来连接交换机跟主机或者其他网络设备
Select the appropriate media, cables, ports, and connectors to connect switches to other network devices and hosts
确保测试每个物理服务器的双向通信，因为交换机对每个端口的入站和出站通信可能配置有误。
Make sure to test both ways from each physical server, as switch ports can be mis-configured for inbound and outbound per port.
