Rpm-Tp (Twisted Pair) - GarrettCom Magnum 1016 Installation And User Manual

Magnum 1000 Workgroup Hubs
2.4.7 RPM-TP
The Magnum RPM-TP card supports Ethernet twisted pair segments of any
standard length. It is equipped with a single RJ-45 connector. The RJ-45 connector is
shielded to minimize emissions and will allow both unshielded twisted pair (UTP) and
shielded twisted pair (STP)
segment connections.
The RPM-TP
module is also equipped with
a slide switch to allow for
cascaded or up-link
connections. This feature
eliminates the need for a
special twisted pair crossover cable.
With the switch in the UP position, the RPM-TP port is used for up-link
connections (i.e.: a connection to another repeater or hub typically.) When used for
segments going to workstations and other user device connections, the switch should be
in the DOWN position. Proper switch position can be verified by noting that the port's
LINK LED will illuminate when proper link is established.
The RPM-TP will support 10BASE-T unshielded twisted pair wiring (UTP)
environments with maximum segment distances up to 100m (325 ft.), or shielded
twisted pair wiring (STP) of 150m (500 ft.). This module is designed with internal
transceiver functionality. The RPM-TP has LINK, PART (inoperative on Model 1000
Hubs), and RX LEDs.
Important Note: For the RPM-TP MDI-X Crossover Switch -
The RJ-45 pins normally (TP crossover switch DOWN) are per the standard for hubs-to-
users twisted pair wiring: 1 = receive+, 2 = receive-, 3 = transmit+, 6 = transmit-, other
pins not used. When the TP crossover switch is UP, the pins of the RJ-45 port are per
the standard for up-links using twisted pair wiring, i.e., the transmit and the receive pairs
are exchanged: 1 = transmit+, 2 = transmit-, 3 = receive+, 6 = receive-, other pins not
used.
