9.Reinstall the cables that were removed in step 2 and 3. Ensure that the RS-232/RS-422 ribbon cable is plugged into the proper receptacle for either RS-232 or RS-422, as appropriate.

10.Reinstall the switcher’s front panel and cover. See Closing the switcher on page B-3.

If you choose to check for proper operation before putting the cover back on, ensure that tools and hands are outside the switcher and then perform step 11. After recognizing the new IC, the switcher should power up normally. Unplug the AC power cord, and reinstall the switcher.

11.Reinitialize the switcher to recognize the new IC as follows: a. Connect the power cord to the AC power source.

b. Press and hold the Enter button while you connect the power cord to the switcher.

c. Observe that the Input, Output, Preset, View, and Esc LEDs all flash. d. Release the Enter button.

12. Ensure that the switcher is working properly.

13.If the switcher was removed from a rack, remove its power cord, reattach the switcher to the rack, and reconnect the power cord.

14. Reconnect the input and output cables.

Replacing the AC fuse

To replace the AC fuse, do the following:

1.Follow the instructions in Opening the switcher on page B-2 for removing the top cover.

2.Locate the fuse on the power supply board (see figure B-2), and remove the fuse from its retaining clips.

3.If test equipment is available, you can check the fuse.

4.Place a new 2A/250V fast-blow fuse in the retaining clips.

5.Reinstall the switcher’s cover as described in Closing the switcher on page B-3.

If you choose to check the switcher for proper operation before putting the cover back on, ensure that tools and hands are outside the switcher, and then connect the power cord to the unit and to an AC source. The switcher should power up normally. Unplug the AC power cord, and reinstall the switcher.

6.Attach the power cord to the switcher and to the AC power source. Make sure the switcher is working properly.

7.If the switcher was removed from a rack, remove its power cord, reattach the switcher to the rack, and reconnect the power cord.

8.

Reconnect the input and output cables.

Button Labels

Eight sets of button labels are provided on the next page. Feel free to cut them out of the manual, write button information in each button area as desired, and put them in the switcher’s label window.
