Overview The FastHub 116T is an unmanaged 16-port 100BaseT Class II repeater for workgroups and server farms. It is a member of an extended network system of stackable, modular LAN and WAN products that increase LAN performance, connect remote offices and users, and provide secure access.
(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).

The redundant power system LED shows the status of the RPS (see Table 1-2). Table 1-2 Color Solid green Solid amber Flashing green 1-4 FastHub 116T Installation Guide LEDs and Mode Button Port status LEDs Mode Collision button RPS LED Description RPS Status Power OK (no RPS or RPS not powered up).
SYSTEM LED The system status LED shows whether the FastHub is powered up and provides an indication of any problem with the main system board of the FastHub (see Table 1-3). Note The system status LED and RPS LED are used together to isolate internal power supply or RPS problems.
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).
