6.2 REPLACING THE ENTIRE FAN ARRAY
In the event of a fan failure, LARCAN recommends replacing the entire array, as all fans have a similar lifespan.
1. Remove the fan array as described in Section 6.1.
2. Slide the new fan array into the MXi. The power connection is aligned so that it connects when the
mounting plate is fully in place.
3. Insert and tighten the five mounting screws. Note: Screws only need to be snug; do not overtighten.
6.3 REPLACING A SINGLE FAN
1. Remove the fan array as described in Section 6.1.
2. Each of the four fans is attached to the mounting plate via two screw-and-nut assemblies. Remove the
screws and nuts and set aside.

3. Disconnect the three-pin wiring harness connection by gently sliding it back with a fingernail or small
plastic tool.
4. If necessary, carefully cut and remove the zip tie holding the wires to the fan frame.
5. Remove the defective fan and replace with a known good fan of exactly the same dimensions and
specifications.
6. Re-connect the three-pin wiring harness connection.
7. Re-fasten the two screw-and-nut assemblies holding the fan to the mounting plate.
8. If necessary, replace the zip tie holding the wires to the fan frame.
