100BASE-TX Distance Extender Module
The 100BASE-TX Distance Extender Module
(3C16683) is designed for use with 3Com’s
SuperStack
®
II Dual Speed Hub 500 12- and
24-port versions (3C16610 and 3C16611).
When installed in a Dual Speed Hub 500 unit, the
Module provides a single 100Mbps Fast Ethernet
twisted pair 802.1D bridged port. You can use
this port to provide a high-speed connection, up
to 100m long, to another segment of your
network infrastructure, or to a local server or
endstation.
The Module also enables you to overcome the
Fast Ethernet network design limitations by
forming chains of almost limitless numbers of
hubs; each link of category 5 cable being up to
100m in length.
This Module operates at half duplex (HD) mode
only.
Examples of network configurations and more
information about Fast Ethernet configuration
rules can be found in the hub’s user guide.
When the Module is fitted in a managed Dual
Speed Hub 500 unit, it provides traffic statistics,
link status and duplex mode. You may also enable
and disable the port.
Technical Specification
Forwarding Rate: 148,800 frames per second.
Forwarding Mode: fragment-free.
Operating temperature: 0–50°C (32–122°F).
Humidity: 0–95% non-condensing.
Power consumption: 5W maximum.
The Module is VLAN and LSA compatible. It filters
all frames smaller than 64 bytes in size. Frames
greater than 1522 bytes are forwarded, unless
there is traffic congestion, when they are rejected.
It forwards all other traffic, such as normal traffic
and multicast frames. No address filtering is
performed.
Standards
Electromagnetic Compatibility
FCC Statement:
This equipment has been tested with a Class A computing device and
has been found to comply with part 15 of FCC Rules. Operation in a
residential area may cause unacceptable interference to radio and TV
receptions requiring the operator to take whatever steps are necessary
to correct the interference.
CSA Statement:
This Class A digital apparatus meets all requirements of the Canadian
Interference-causing Equipment Regulations.
Cet appareil numérique de la classe A respecte toutes les exigences
du Règlement sur le matériel brouilleur du Canada.
