100BaseTX Distance Extender Module
This module has a special distance extending port that sends data at
100Mbps over regular 100BaseTX Category 5 cabling. The distance exten-
der module sends your data up to 100 meters (328 feet). This module is
ideal for connecting to file servers or uplinking to remote hubs.
This module is available for the Rack Mountable Auto-Sensing hubs, (No.:
EFAH16, EFAH24):
EFFETXDE: 100BaseTX Distance Extender Module (Single Port)
When this module is used on the EFAH24, port 12 cannot be used. If the
module is used on the EFAH16, port 15 cannot be used. The module uses
up one connection on the hub, and thus one of the ports becomes disabled.
These rules apply only to times when the module is in use.
Up to four 100BaseTX hubs can be connected together when this module
is used in an auto-sensing hub. Since the 100BaseTX Distance Extender
module is a switched port, another 100BaseTX hub can be cascaded to the
hub with the Distance Extender module installed in it. In addition, two
100BaseTX hubs cascaded together can be connected to the 100BaseTX
Distance Extender module. The usual Fast Ethernet distance limitation
apply when cascading two 100Mbps hubs together, (see page 4 for details).
The distance extender port on the add-on module can be disabled by
removing the corresponding jumper on the module. In the Auto-Sensing
hubs, this module can only be used in half duplex mode
You need to use a crossover cable to connect the module to another hub. If
you are using a straight-through cable, you must run the cable between the
module and the uplink port on the second hub (see illustration on page 17).
The module’s Link LED will light up when a connection is made and the
Activity (ACT) LED will flicker while data is being transmitted or
received.
