2.2 NETWORK DESIGN GUIDELINES
Review the guidelines in this section before you install the
MR-9000TPT.
•
A shielded twisted pair segment can be no longer than 150
meters (492 feet).
•
An unshielded twisted pair segment can be no longer than
100 meters (328 feet).
•
A thick-net segment can have a maximum of 100 transceivers,
spaced at least 2.5 meters apart. Transceiver cable taps
should be placed on the black bands on the cable. (The bands
are placed at 2.5 meter intervals.)
•
The transceivers that the MR-9000TPT will be connected to
must have their SQE test function turned off.
•
The AUI cable that connects the MR-9000TPT to a
transceiver must be IEEE 802.3 type cable and must be 50
meters or less in length.
•
From its source address to its destination address, a data
packet may pass through a maximum of four repeaters and
five cable segments. If you use five segments of cable, two of
those segments must be inter-repeater links, that is, point-to-
point cable segments with no taps.
