5 Port Connections This chapter focuses on making connections to the wireless controller’s network interfaces, including details on network cable specifications. The wireless controller features two 1000BASE-T RJ-45 ports for network connections. The sections that follow describe these interfaces.
Chapter 5 | Port Connections Cable Labeling and Connection Records Cable Labeling and Connection Records When planning a network installation, it is essential to label the opposing ends of cables and to record where each cable is connected. Doing so will enable you to easily locate inter-connected devices, isolate faults and change your topology without need for unnecessary time consumption.
Chapter 5 | Port Connections Understanding the Port Status LEDs Understanding the Port Status LEDs The wireless controller includes LED indicators for each port to indicate link status and network activity. The port LEDs are shown below and described in the following table. Figure 12: Port Status LEDs 1 1 Port 1-2 Link/Activity LEDs Table 3: Port Status LEDs LED Condition Status Link/Activity Green Port has a valid link. Flashing Green Flashing indicates activity on the port.
Chapter 5 | Port Connections How to Connect to Twisted-Pair Copper Ports How to Connect to Twisted-Pair Copper Ports The RJ-45 ports on the wireless controller support automatic MDI/MDI-X pinout configuration, so you can use standard straight-through twisted-pair cables to connect to any other network device (PCs, servers, switches, routers, or hubs). Each connection requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends.
Chapter 5 | Port Connections How to Connect to Twisted-Pair Copper Ports 10/100BASE-TX Pin All 100BASE-TX RJ-45 ports support automatic MDI/MDI-X operation, so you can Assignments use straight-through or crossover cables for all network connections to PCs, switches, or hubs. In straight-through cable, pins 1, 2, 3, and 6, at one end of the cable, are connected straight through to pins 1, 2, 3, and 6 at the other end of the cable. Figure 13: RJ-45 Connector 1 1 RJ-45 Pin Numbers.

A Troubleshooting Diagnosing LED Indicators Table 9: Troubleshooting Chart Symptom Action Pwr/Sys LED is Off ◆ ◆ Pwr/Sys LED is on Yellow ◆ ◆ Link/Act LED is Off ◆ ◆ ◆ ◆ Check connections between the PSU, the power cord and the wall outlet. Contact your dealer for assistance. Power cycle the switch to try and clear the condition. If the condition does not clear, contact your dealer for assistance. Verify that the switch and attached device are powered on.
Appendix A | Troubleshooting Power and Cooling Problems Power and Cooling Problems If the power indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or power supply unit. However, if the unit powers off after running for a while, check for loose power connections, power losses or surges at the power outlet. If you still cannot isolate the problem, the power supply unit may be defective.
