Hardware Procedures

This appendix describes how to perform hardware upgrade procedures such as swapping the RS-232 and RS-422 ports, installing a new firmware update, and replacing the fuse.

Opening the switcher

Before you can perform any of the hardware upgrade procedures, you must open the switcher. To open the switcher, do the following:

1.Disconnect the power cord from the switcher.

2.If the switcher is rack mounted, remove the switcher from the rack and place it on a clean workspace.

3.Remove the eight screws that secure the switcher’s top cover (figure B-1).

	cable
	Pin 1

NOTE: If you are also installing a firmware update, remove two screws in this location on the bottom cover.

4.Lift the top cover straight up. Lift the cover evenly to clear the grooves at the edge of the rear panel.

5.If you are updating the firmware, remove the two screws at the front edge of the bottom cover, and the four screws and washers securing front panel to the bottom cover. Three internal cables connected to the front panel can be damaged if strained. Carefully tilt the front panel away from the main body of the switcher.

6. If you are updating the firmware, remove the top cable by pressing the two receptacle tabs on the top cable outward, as shown at the left, and pulling back gently on the cable connector to remove it

from the receptacle. Lay the front panel down in front of the switcher.
