KNE24TX/RS User’s Guide - Rev. A01 
Intended Audience:  This manual assumes that the user has a general working 
knowledge of networking principles and its architecture. 
 
Congratulations on the purchase of your Kingston Fast EtheRx Stackable 
100BASE-TX 19” Rack-Mountable Fast Ethernet Hub. There are three models 
available: KNE8TX/RS, KNE12TX/RS, and KNE24TX/RS, 8-Port, 12-Port, 
and 24-Port Fast Ethernet hubs, respectively. The Fast EtheRx models are 
100BASE-TX Class 
I
 and Class 
II
 compliant repeaters which conform to 
IEEE 802.3u 100Mb/s CSMA/CD (Carrier Sense Multiple Access with 
Collision Detection) networks using Category 5 Unshielded Twisted Pair 
(UTP) cabling.  There is also an optional 100BASE-FX plug-in module 
available for either SC or ST-type connectors. The Fast EtheRx 100BASE-TX 
hubs operate at 100Megabits per second (Mbp/s) out-performing standard 
10BASE-T Ethernet 10Mb/s operation by up to 10 times faster. 
 
The Fast EtheRx hubs offer eight (8), twelve (12), or twenty-four (24) UTP 
ports for 100BASE-TX Fast Ethernet connections. The last UTP port offers 
two RJ-45 connectors to support both crossover or straight-through cable wiring 
for uplinking to one other 100BASE-TX Class 
II
  repeater. The Fast EtheRx 
hubs can also be stacked (using any combination of these 3 models) up to six 
hubs using the stacking cable provided.  This allows a maximum of 48, 72, or 
144 UTP ports (depending on the model) on a single collision domain. The 
Fast EtheRx hubs can be used on desktop or 19-inch rack-mount installations 
(mounting hardware included).  For easy trouble-shooting, the front panel 
includes a variety of diagnostic LEDs including: Power, Collision, Utilization 
and UTP port LEDs which display Link, Activity and Partition/Error status. 
 
For the remainder of this manual, the Fast EtheRx Stackable Fast Ethernet 
Hubs will be referred to collectively as the Fast EtheRx Hubs.  For clarity, the 
three models will be differentiated as follows: 
 
 
KNE8TX/RS – Fast EtheRx Stackable 8-Port Fast Ethernet hub
 
 
KNE12TX/RS – Fast EtheRx Stackable 12-Port Fast Ethernet hub
 
 
KNE24TX/RS – Fast EtheRx Stackable 24-Port Fast Ethernet hub
