In the case of chassis units, replacement boards must be inserted and the RFS 
re-booted.  

1  Always use a static grounding wrist strap before handling any board—do not 

attach the wrist strap to any painted surface on the chassis unit. 
 

 

Note 

It is not necessary to unplug the NCU or the ACU prior to removing or 
inserting a board. 

 

2  Facing the chassis unit, remove the card that is to be replaced, or the blank 

faceplate, following these guidelines: 

∙ 

Loosen the blue knurled knobs on both sides of the board. 

∙ 

Pull firmly to unseat the board from the connectors inside the chassis unit. 

∙ 

Gently slide the board straight out and away from the chassis unit so as 
not to damage any components contained on the board. 

3  Remove the new board from its antistatic packaging and insert it into the 

chassis unit as shown in the following illustration, and follow these guidelines: 

∙ 

Do not jam the board in any way while inserting it. 

∙ 

Do not mount the board in any orientation other than that specified in the 
diagram. 

∙ 

Insert the board straight into the chassis unit so as not to damage any 
components contained on the board. 

∙ 

Press firmly to seat the board into the connectors within the chassis unit. 

∙ 

Tighten the blue knurled knobs on each end of the board finger tight 
only—do not use a screwdriver to tighten the screws and do not over 
tighten.
