Magnum 1000 Workgroup Hubs Installation and User Guide (04/02)

2.4.1RPM-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 take advantage of internal termination, the slide switch should be in the "DOWN" (or right-side) position. In this configuration, the 10BASE2 segment is directly attached to the BNC port where it is internally terminated. When the switch is in the "UP" (or left-side)

position, the BNC port	Standard BNC	Internal Termination

require a "tee" connector,

used as a tap, to allow the 10BASE2 coax segment to continue on past the RPM-BNC connection.

The RPM-BNC module includes one partition (PART) and one receive (RX) LED, which are visible from the exterior. (The PART LED is inoperative on Model 1000 Hubs because the logic necessary to drive the LED is not included in the design.) The RX LED illuminates GREEN intermittently to indicate data is being received.

Important Note: for the RPM-BNC Termination Switch -

DOWN (or right): Internally Terminated

UP (or left): Requires "T" Connector.

2.4.2RPM-AUI

This module is equipped with a 15 pin female AUI connector and a slide-lock, and performs full IEEE 802.3 repeater functionality. It is used to provide connectivity with a 10BASE5 (ThickNet) backbone or to any AUI segments. A transceiver is

required when connecting to a ThickNet segment and the RPM-AUI supports this convention. The RPM-AUI is also a "universal" Ethernet media interface as it may be
