Important: The switch must be located within 100 meters of its attached 10BaseT or 100BaseTX devices.
Use the following guidelines to determine the cabling requirements for the network devices:
• Connecting to Network Station: Category 5 UTP (Unshielded Twisted-Pair) straight-through cable (100 m
maximum) with RJ-45 connectors
• Connecting to Repeater/Hub/Switch’s Uplink port: Category 5, UTP straight-through cable (100 m maximum)
with RJ-45 connectors
Note: These switches have no specific uplink ports. All 10/100/1000 ports on these switches are auto-sensing
MDI/MDI-X. This advanced feature means that when the ports are operating at 10/100Mbps, they will automatically
determine whether the device at the other end of the link is a hub, switch, or workstation, and adjust its signals
accordingly. No crossover cables are required.
Although 10/100BaseT requires only pins 1, 2, 3, and 6, you should use cables with all eight wires connected as
shown in Table 2-2 below.
1000BaseT requires that all four pairs (8 wires) be connected correctly, using Category 5 or better Unshielded
Twisted Pair (UTP) cable (to a distance of 100 meters). Table 2-2 shows the correct pairing of all eight wires.

2.6.2 Gigabit Ethernet Ports Cabling Procedures
Cabling requirements for the optional hardware modules depend on the type of module installed. Use the following
guidelines to determine the particular cabling requirements of the module(s):
• 1000BaseSX GBIC: Cables with SC-type fiber connectors; 62.5µ multi-mode fiber (MMF) media up to 275 m
(902'), or 50µ MMF media up to 550 m (1805')
• 1000BaseLX GBIC: Cables with SC-type fiber connectors; 10µ single-mode fiber media up to 5 km (16,405')
