		Replacing Processor Card Components
Replacing DIMs
Introduction
	There are two Data Interface Modules (DIMs) on a 6500PLUS processor card.
Description
	Each DIM is a 64-pin, dual in-line module that can be repositioned so that Ports 1 or
	2 act as either DCE or DTE ports. For most cases, the DIMs are positioned so the
	ports act as DCEs. One DIM corresponds to Port 1 and the other to Port 2
	(Figure 2-18). While most 6500PLUS processor cards contain EIA 232-D DIMs, you
	can purchase DIMs that will support V.35, V.36, and X.21 interfaces.
Replacement
	Use the DIM Extraction Tool (58862-01) provided with the accessory kit to perform
Procedure	the following procedure. Do not use a screwdriver or other tool that may damage the
	components on the card.
	Caution
	6500PLUS cards and their components are sensitive to static discharge, which can
	damage components. Use proper handling and grounding precautions, including the
	use of an anti-static grounding strap, whenever you handle a card.
	Step	Action
	1	Remove the TRIM card first if you are installing or replacing DIMs onto
		a processor card that has an attached TRIM card.
		Otherwise, there is no physical support to the processor card when you
		insert the DIMs on the board.
	2	Lift A DIM from its socket as shown in Figure 2-18,using the DIM
		removal strap to lift out the DIM. Be sure that you do not bend the pins
		during removal.
	3	Insert the DIM into the other set of parallel sockets if you are moving the
		DIM to another position.
	4	Insert the new DIM into the original location if you are just replacing a
		DIM. Be sure the pins are seated firmly in the sockets and are not bent.
	5	Reattach the TRIM card to the processor card.
