Magnum 3000 Stackable HubsInstallation and User Guide (07/06)
Important Note: For the RPM-TPMDI-X Crossover Switch - DOWN(or Right) for workstations and user connections. UP (or Left) for Up-Link connections to other hubs, etc.
(To help recall the right TP switch position, remember "up for up-link" ! )
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.
4.2.8BPM-BNC
The Magnum BPM-BNC bridge module is equipped with a standard 10BASE2
coax BNC connector. This BPM is self-learning and filters and forwards packets at full Ethernet wire speed. This module is used for 10BASE2 connections and is designed to isolate the local segment (i.e., the local nodes connected to the Magnum unit housing the BPM internally) from the connecting network (i.e., the nodes of external users and devices connected through the BPM’s media connector).
The BPM-BNC module is designed with a special switch -selectable internal termination function that eliminates the need for a "tee" connector and a 50 ohm terminator. For switch details, refer to the RPM-BNC section, 3.2.1
The BPM-BNC module includes an FWD-I LED and an FWD-X LED, which
