Replacing a fan in Universal Videohub
Each fan is designed to be replaced without needing to switch off power to Videohub.
Step 1. Locate the fan tray at the base of the unit.
Step 2. Using a number 01 Phillips head screwdriver, remove the left and right screws from the fan tray.
Step 3. While supporting the tray, remove the center screw.
Step 4. Having removed all three screws, slowly allow the fan tray to swing open until you see the
black plastic dust filter on top of each fan.
Step 5. Gently pull the tray towards you while continuing to swing it down until you feel the rear of
the tray detach from the Universal Videohub chassis. Note which fan is faulty.
Step 6. You will see the colored power cables connected to each fan. Each fan power cable connects
to the Videohub motherboard with a plastic connector. While supporting the fan tray, unplug
the plastic power connectors of all three fans. The fan tray can now be fully removed.
Step 7. Place the fan tray on a flat surface and unclip the top of the dust-filter housing using the
four clips.
Step 8. Remove the top of the housing and the filter. Four screws will be revealed. Remove the four
screws around the faulty fan. Then remove the base of the dust filter housing and also the
faulty fan.
Step 9. Replace the fan with a spare unit and then reinstate the base of the dust filter housing. Secure
the housing and fan with the four screws and ensure the heads of the screws recess into the
dust filter housing. If the screws fail to recess, flip over the housing and try again.
Step 10. Place the dust filter over the base of the housing and then snap on the top of the dust
filter housing.
Step 11. Position the fan tray underneath the base of the Universal Videohub chassis and connect all
three fan power cables to the motherboard. All three fans should immediately start running.
Step 12. Gently dock the rear of the fan tray with the Universal Videohub chassis. Swing up the front
of the fan tray and simultaneously push the tray towards the Videohub motherboard until the
rear of the fan tray slides into place and the front swings shut.
Step 13. Reinstall the three screws.
