    (see Figure 1-2). All ports are compatible with the 100BaseTX IEEE-802.3u specification and can connect to any 100BaseTX device through standard Category 5 unshielded twisted-pair (UTP) cable. 1-2 FastHub 116T Installation Guide Feature Summary Description • IEEE 802.3u Class II repeater compliant.

    Ports 1x through 16x have their transmit (TD) and receive (RD) pairs internally crossed. Standard Category 5 UTP crossover cable is required when connecting these ports to another hub, switch, or router (unless you are connecting to the uplink port on another FastHub or 100BaseT hub).

    This indication remains until the link fault is corrected. Possible causes are autopartition, jabber, and isolated (carrier integrity error). Note that this state should not be confused with the “no link status” (link down) indication where the link is not operational. 1-6 FastHub 116T Installation Guide Port Status LED Description Port Status No link (link down).
