Installing the Series 5400zl Switches Installing the Series 5400zl Switches Installation Procedures 1. Prepare the Installation Site Cabling Infrastructure Ensure the cabling infrastructure meets the necessary network specifications. See the following table for cable types and lengths, and see appendix B, "Switch Ports and Network Cables" on page B-1 for more information: Table 2-1. Summary of Cable Types to Use with the Switch Port Type 10/100/1000BASE-T Cable Type Twisted-Pair Cables For either 10, 100 Mbps or 1000 Mbps operation: Category 5 or better, 100-ohm UTP or shielded twisted-pair (STP) balanced cable. For 1000 Mbps (gigabit) operation, Category 5e cabling or better is recommended. Length Limits 100 meters Note: The ProCurve 10/100/1000-T zl Modules and 100/1000-T Transceiver are compatible with the IEEE 802.3ab standard including the "Auto MDI/MDI-X" feature, which allows use either straight-through or crossover twisted-pair cables for connecting to any network devices including end nodes, such as computers, or to other switches, hubs, and routers. The Auto MDI/MDI-X feature only works when the port is in auto-negotiation mode. Fiber Optic Cables Gigabit-SX (on Gigabit-SX-LC mini-GBIC) Multimode fiber-optic cables fitted with LC connectors 220 meters to 550 meters depending on the cable used. See "Fiber-Optic Cables" on page B-3 for more information. Gigabit-LX (on Gigabit-LX-LC mini-GBIC) Single-mode fiber-optic cables fitted with LC connectors. The multimode cables specified for the GigabitSX mini-GBIC may also be used, but a modeconditioning patch cord may be needed - See the Installation Guide that came with your module for more information. • single-mode cable = 10 kilometers • multimode cable = 550 meters Gigabit-LH (on Gigabit-LH-LC mini-GBIC) The same single-mode fiber-optic cables as for • 70 kilometers Gigabit-LX. Note: Gigabit-LH - Between the transmit and receive ends of the cable, at least 5db of attenuation is required for a reliable connection. This is equivalent to 20km of the fiber-optic cable. For distances less than 20km, you must add attenuators to bring the total attenuation to at least 5db. Most cable vendors carry attenuators. 2-7
