AN EMOVAL
The fans utilized by the HPOD are designed for long life even in a harsh environment. They
are still mechanical devices subject to wear and may need replacement after several years. In
dusty environments, their removal facilitates clearing the heat sink of accumulated dust.
To remove the fan assembly:
Step Procedure
1 Disconnect power from the SSPA
2 Loosen the six captive fasteners as indicated in Figure 5-2.
3 Note: Be certain to use an appropriate screwdriver, such as the one provided with the
SSPA, to avoid damaging the fasteners.
4 Remove the fan assembly far enough to gain access to the two circular fan connectors.
5 Disconnect the circular fan connectors and remove the assembly.
