Cisco VXC-2112: Disassembly 

Disassembling the Cisco VXC-2212

This is fairly straight forward, but it's not a 30-second job to upgrade the RAM or DOM.

Cisco VXC-2112 bottom view Turn the unit over to show the bottom(?) - or at least the bit carrying the label. You start by removing the six screws indicated.

Now to start on the case. We need to separate the top from the bottom. Hold it label side down....

Cisco VXC-2112 opening case I found a good starting point was under the left-hand mounting lug. A little pressure started the separation process.

Cisco VXC-2112 opening left-hand side From there I moved to the left-hand-side, and then round the corner....

Cisco VXC-2112 opening right-hand side ....and from there it was back to the middle and then work around to the right-hand side.

Cisco VXC-2112 three edges free At this point three edges are free. I found that it didn't take much persuasion over the last edge as you can move the cover away from you which helps to clear the internal clips.

With the plastic cover out of the way the electronics are now visible.

First remove the four nuts by the video sockets and then the two screws below. At this point it is worth using a flat bladed screwdriver to ensure that the black paint isn't holding the two metal tabs to the panel behind them.

Cisco VXC-2112 main circuit board With the top board removed the main circuit board is revealed. The 44-pin horizontal DOM can be seen top-leftish in the photo. One further step is necessary to get at the RAM that is mounted on the bottom of the main circuit board. You need to remove the four screws indicated in order to do this. .

Cisco VXC-2112 RAM With the main circuit board free it can be moved clear of the metalwork and turned over to reveal the RAM module - a standard SODIMM.

Note: I disassembled the unit without unplugging any of the internal cabling. I didn't find it to be necessary.

As always just reverse the procedure to reassemble the VCX-2112.
