Page 13: Chapter 2 Network Requirements/Specifications
2.1.1 AUI Port Requirements When connecting a network segment to the IRM, via a transceiver and an AUI Cable, the following requirements must be met: • Transceiver - The transceiver to which the IRM will be connected must meet Ethernet Version 2, or IEEE 802.3 standards. -
Page 14: Operating Specification
Length - The thin-net segment must be no longer than 185 meters. • Terminations - A 50 ohm terminator must be connected to the far ends of each thin-net segment. The BNC port on the IRM is not internally terminated. •... -

Cabletron Systems' Technical Support immediately. SETTING THE IRM JUMPERS On the IRM are five jumpers (See Figure 3-1). Three of the jumpers, JP2, JP4, and JP5, can be changed. JP1 is for Cabletron Systems use only and should not be changed from its default positions. JP3 is not used. - Page 20 Jumper Figure 3-1 IRM Jumper Locations will be saved if power should fail to the MMAC, or if the IRM is removed from the MMAC. When set to the disabled position, all parameters entered into the IRM will be lost after approximately 10 minutes.

Page 21: Setting The Default Setting Jumper (Jp4)
Setting the Default Setting Jumper (JP4) The repeater module is shipped with JP4 in its normal operating position, over pins 1 and 2, and should not require setting as part of the IRM installation. However, when necessary, the IRM's network management parameters can be set to their default values using the Default Setting Jumper (JP4, Fig 3-1). -

Install the IRM into the MMAC as follows: 1. Power off the MMAC. 2. Slide the IRM (3, Fig. 3-2) into Slot 1(4) of the MMAC's (1) card cage. Be sure that the card is in the top and bottom slot guides. -
Page 23: Connecting The Irm To The Network
To connect to the network via either AUI Port: CAUTION: Be sure to disable the SQE test function on the transceiver will be connecting to the IRM's AUI Port. Failure to do so will result in improper operation of the IRM. Refer to the applicable transceiver manual. -
