Maintenance & Troubleshooting
To replace a fan
• #2 screwdriver to remove and install the fan cover assembly.
• Curved tweezers to disconnect the fan’s power connector from the KMX-3901 card.
• Anti-static bag or anti-static work surface to reduce the possibility of electrostatic
discharge damage to the card.

To replace a fan
1 During off hours when the system is not in use, eject the card from the multiviewer’s
frame. See
2 Place the card on an anti-static bag or anti-static work surface.
3 Using curved tweezers, disconnect the fan power connector plug, very carefully; gently
wiggle the connector plug from the socket (jack). Do not pull on the wires. If the wires
are routed through wire holders, remove the wires from the holders first, before
disconnecting.
4 Free up the fan cover assembly by removing the 2 screws in the middle.
Once the 2 screws are removed, remove the fan cover assembly.
