The panel removed. I tried to coil up the excess white cable, but could not get it to fit. Pushed the Cat-5 connector down inside the post.
You remove the ten screws on the top panel. Pull the back side down to release the plastic pop slots (one in each corner). Then the whole panel slides forward to release.
The posts are held in by one screw and three plastic pop slots. While I was at it, I installed the ham radio Larson glass mount antenna and hid the cable in the right post cover.
