Qprj-Msc, "3 + 1" 3@10/100Mb Rj-45 And 1@100Mb Fib; Qprj-Mst, "3 + 1" 3@10/100Mb Rj-45 And 1@100Mb Fib - GarrettCom Quad Installation And User Manual

Magnum Quad-Series Fiber Switches
Important Note: For the QPM-RJ45 Crossover Push-button -
The RJ-45 pins normally (TP crossover push-button 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 push-button 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.
5.2.7 QPRJ-MSC, "3 + 1" 3@10/100Mb RJ-45 and 1@100Mb Fiber SC
Multi-mode Connector, "Combo" Quad-Port Module
The QPRJ-MSC "3+1
Combo" quad-port supports three auto-
negotiating twisted pair ports at
10/100Mbps FDX / HDX, and one fiber
port with 100Mbps multi-mode FX SC
connector. The three RJ-45 ports on the
right operate the same as those in the
same place on the QPM-RJ45 module.
The fiber SC connector
functions as a fiber optic transceiver to support 100BASE-FX network segments. When
installed in a Quad-Series Fiber Switch, it supports fiber cable distances up the IEEE-
standard 100Mbps distance limits, i.e., typically 2km at full-duplex and 412m at half-
duplex. The factory default setting is for full-duplex operation, and a jumper on the
module must be moved to select half-duplex. (See Section 3.4).
Each 3+1 combo port has an Activity (ACT) LED indicating packets being
received, a Link (LK) LED that indicates proper connectivity with the remote device
when lit, a FDX/HDX LED to indicate full-duplex mode when lit (or half-duplex when
off). In addition, the RJ-45 ports have a "speed" LED indicating 100Mb when lit (or 10
Mbps when off). The fiber port is always 100Mbps speed.
5.2.8 QPRJ-MST, "3 + 1" 3@10/100Mb RJ-45 and 1@100Mb Fiber ST
Multi-mode Connector, "Combo" Quad-Port Module
The Magnum QPRJ-MST is also a 3+1 Combo quad-port. It is the same as the
QPRJ-MSC "3+1 combo" module except the multi-mode fiber port is ST-type. See
Section 5.2.1 for a description of the 100Mb multi-mode-mode fiber SC-type port.
