Hardware Upgrades and Maintenance
This chapter contains procedures for performing hardware maintenance
procedures such as swapping the RS-232 and RS-422 ports, installing a new
firmware update, and replacing the fuse.

2. If the switcher is rack mounted, remove the switcher from the rack and place
it on a clean workspace.
3. Remove the fourteen screws (8 top screws and 6 side screws) that secure the
top cover of the DXP (figure 6-1).
