Remove Card Guide Frame

There's a hard and an easy way. To save time, the easy way is to remove both fans by unscrewing the four gold colored screws on the top of the card guide and sliding the fans (still in their metal mounts) up and out of the card guide.

Now all three mounting screws are visible AND accessible. Remove all three screws and lift the card guide out.

Install Card Guide Frame

One way is to just start the three gold mounting screws into the case. Place the frame just to the rear of the screws and slide it forward until the frame is seated against all three screw. Now tighten them down. Reinstall the fans.

Remove and Install P2SC Heatsink

The best way to do this is with the planar out of the case, otherwise the front outer nut is hard to start by hand. Note: Align the heatsink fins so that they are parallel to the air flow. In other words, so the air can blow in between the fins.

Remove Planar

Remove front card guide frame. Unplug rear fan, remove memory card rear guide, pull fan off rubber mounts. Unplug all planar power and signal connectors. Remove the parallel port and external SCSI port posts. Remove all planar mounting screws.

Pull planar towards front of case until the ports clear their case cutouts at the rear. Pivot rear of board up and forward until you can remove it.


The S.6 memory card illustration is HERE.

The memory modules for Model 397 must be installed either in pairs (2 cards) or quads (4 cards). Each card in a pair or quad must be of equal capacity. If only a pair of memory modules is installed, use slots D and H. If a quad is installed, use slots B and F, in addition to slots D and H.
