The Magnum BPM-BNC bridge module is equipped with a standard 10BASE2 coax connector. This BPM is self-learning and filters and forwards packets at full Ethernet wire speed. This module is used for 10BASE2 ThinNet (commonly referred to as BNC) connections and is designed to isolate the local segment (i.e., the users and devices connected to the Magnum unit housing the BPM) from the connecting
network (i.e., the users and devices connected through the BPM’s media connector).
2.4 Bridge Port Modules (BPMs)
To provide optional local segment isolation, individual Bridge Port Modules (BPMs) are available for Magnum 700Xs. For flexibility, any port of a Magnum 700X may be configured with a BPM. Multiple (up to 6) BPMs may be configured in one 700X chassis..
There are four different BPM cards and each is designed with its own media connector type. BPMs are available for the following Ethernet media types: BNC (ThinNet or 10BASE2), AUI (10BASE5 or ThickNet, DB-15 female for most transceiver connections), ST (Ethernet multi-mode Fiber ST), and RJ-45 (10BASE-T UTP and STP). They are shown in Figure 2.4. Each BPM is usually factory installed, but may be field installed by trained technicians as described in Section 3.0, Installation.

Each of the individual BPMs are described in detail in this section.
