Replacing the AC fuse

The AC fuse on the power supply board is a user-replaceable component of the Matrix 50 Series switchers. To replace the AC fuse, do the following:

1.Follow the instructions in Opening the switcher on page B-2 to remove the top cover.

2.Locate the fuse on the power supply board (figure B-7), and remove it 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. See 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.

Setting the front panel jumper

If the front panel jumpers are set incorrectly (for example, if the matrix configuration was changed and the jumpers were not updated), when the switcher is powered up, it locks up and will not operate. If the switcher is connected to a PC or control system, it reports Invalid Jumpers via the RS-232/422 link. Check the setting of the jumper as follows:

1.Follow the instructions in Opening the switcher on page B-2 to gain access to the interior of your switcher, including the instructions to remove the front panel.

2.Locate the front panel jumper (figure B-7).

3.Install the jumpers as appropriate to your Matrix 50 model (figure B-9).
