Foundry Switch and Router Installation and Configuration Guide

Connecting to Ethernet or Fast Ethernet Hubs

For connections to Ethernet hubs, a 10/100BaseTX or 1000BaseT switch, or another Foundry device, a crossover
cable is required (Figure 2.11 or Figure 2.12). If the hub is equipped with an uplink port, it will require a straight-
through cable instead of a crossover cable.

NOTE: The 802.3ab standard calls for automatic negotiation of the connection between two 1000BaseT ports.
Consequently, a crossover cable may not be required; a straight-through cable may work as well.

Connecting to Workstations, Servers, or Routers

Straight-through UTP cabling is required for direct UTP attachment to workstations, servers, or routers using
network interface cards (NICs).
Fiber cabling with SC connectors is required for direct attachment to Gigabit NICs or switches and routers.
