Magnum Quad-Series Fiber Switches | Installation and User Guide (06/03) |
FDX/HDX LED to indicate full-duplex mode when lit (or half-duplex when off), and a “speed” LED indicating 100Mb when lit (or 10 Mbps when off).
Important Note: For the QPM-RJ45 Crossover Push-button - OUT for workstations and user node connections.
IN for Up-Link connections to other hubs, switches, etc.
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.
5.2.7QPRJ-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.
