Magnum 700X - Repeater Port Modules (RPMs)
There are a total of six different RPM cards and each is designed with its own media
cable connector type. A seventh module is used as a face plate when any front slot is not used.
The assortment of standard network connector types for RPMs includes BNC (ThinNet
or 10BASE2), AUI (10BASE5 or ThickNet, DB-15 female for most transceiver connections),
DTE (DB-15 male-AUI for direct connects), ST (Ethernet multi-mode Fiber ST), SC (Ethernet
multi-mode Fiber SC), SMF (Ethernet single-mode Fiber) and RJ-45 (10BASE-T UTP and STP).
They are shown in Figure 2.3. Each RPM is usually factory installed, or may be field installed by
trained technicians as described in Section 3.0, Installation.

RPM-BNC
The Magnum RPM-BNC repeater module is equipped with a standard 10BASE2 coax
connector. This RPM performs full IEEE 802.3 repeater functionality and is used for 10BASE2
ThinNet (commonly referred to as BNC) connections.
The RPM-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. To
