Chapter 6 | Port Connections Copper Cabling Guidelines ◆ Display a copy of your equipment map, including meanings of all abbreviations at each equipment rack. Copper Cabling Guidelines The RJ-45 ports on the switch support automatic MDI/MDI-X pinout configuration, which enables you to use standard straight-through twisted-pair cables to connect to any other network device (PCs, servers, switches, routers, or hubs).
Chapter 6 | Port Connections Copper Cabling Guidelines 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 15: RJ-45 Connector 1 1 RJ-45 pin numbers.

Chapter 6 | Port Connections Fiber Cabling Guidelines such as IP phones and wireless access points, which translates into greater network availability. Fiber Cabling Guidelines The switch provides four slots for SFP-compliant fiber-optic transceivers. Note that all 1000BASE fiber optic ports operate at 1 Gbps full duplex. The 100BASE fiber optic ports operate at 100 Mbps full duplex.
Chapter 6 | Port Connections How to Connect to Twisted-Pair Copper Ports ◆ Do not exceed the minimum bending radius for fiber cables (typically a few inches). ◆ Use cable ties to bundle fiber cables together and secure coiled loops of excess cable. ◆ Do not let fiber cables hang free supporting their own weight. ◆ Do not let fiber cables pull in any way that puts stress on the connectors.
Chapter 6 | Port Connections How to Connect to SFP Fiber Optic Ports How to Connect to SFP Fiber Optic Ports Follow these steps to connect cables to SFP transceiver ports. Warning: This switch uses lasers to transmit signals over fiber optic cable. The lasers are compliant with the requirements of a Class 1 Laser Product and are inherently eye safe in normal operation. However, you should never look directly at a transmit port when it is powered on.
A Troubleshooting Diagnosing LED Indicators Table 13: Troubleshooting Chart Symptom Action PWR LED is Off ◆ ◆ ◆ DIAG LED is blinking Amber ◆ DIAG LED is blinking Amber with PoE Mode button pressed ◆ Link/Act LED is Off ◆ ◆ ◆ ◆ ◆ ◆ ◆ Check connections between the switch, the power cord, and the AC power outlet. Check the AC power outlet is supplying 110-240 VAC. Contact your dealer for assistance. Power cycle the switch to try and clear the condition.
Chapter A | Troubleshooting Power Problems Power Problems If a 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 internal power supply. However, if the switch shuts down after operating for a continuous period, check for loose power connections, power losses or surges at the power outlet. If you still cannot isolate the problem, the internal power supply may be defective.
