Chapter 4: Installing the Switch To install an SFP transceiver, follow these steps: Step 1. Consider network and cabling requirements to select an appropriate SFP transceiver type. Step 2. Insert the transceiver with the optical connector facing outward and the slot connector facing down. Note that SFP transceivers are keyed so they can only be installed in one orientation. -

Chapter 5: Making Network Connections Figure 5-1. Network wiring connections. 5.3 Fiber Optic SFP Devices An optional Gigabit SFP transceiver can be used for a backbone connection between switches, or for connecting to a high-speed server. Each single-mode fiber port requires 9/125 micron single-mode fiber optic cable with an LC connector at both ends. Each multimode fiber optic port requires 50-/125- or 62.5-/125-micron multimode fiber optic cabling with an LC connector at both ends. -

Chapter 5: Making Network Connections Figure 5-2. Making fiber port connections. Step 4. As a connection is made, check the Link LED on the switch corresponding to the port to be sure that the connection is valid. The fiber optic ports operate at 1 Gbps. The maximum length for fiber optic cable operating at Gigabit speed will depend on the fiber type as listed under 1000 Mbps Gigabit Ethernet Collision Domain in Section 5.4. - Page 24 Chapter 5: Making Network Connections Table 5-3.

Chapter 7: Troubleshooting 7.3.2 10BASE-T/100BASE-TX Pin Assignments Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100-ohm Category 3 or better cable for 10 Mbps connections, or 100-ohm Category 5 or better cable for 100 Mbps connections. Also be sure that the length of any twisted-pair connection does not exceed 328 feet (100 meters). -
Page 29: Crossover Wiring
Chapter 7: Troubleshooting 7.3.4 Crossover Wiring If the twisted-pair cable is to join two ports and either both ports are labeled with an “X” (MDI-X) or neither port is labeled with an “X” (MDI), a crossover must be implemented in the wiring. (When auto-negotiation is enabled for any RJ-45 port on this switch, you can use either straight-through or crossover cable to connect to any device type.) You must connect all four wire pairs as shown in the following diagram to support Gigabit Ethernet. -
