Removing an M-SPV/M-SPX

module.
2 Unfold the levers and gently slide the module out.
Replacing a Fan
Caution: The fan may rotate for a short while after it is removed from the Avaya
M770.
Note: Although one fan is sufficient to cool the Avaya M770, it is recommended to
use two fans to ensure maximum resiliance.
The fans are hot-swappable and interchangeable. One fan will fit on either the left or
right side: turn the fan upside down if necessary.
To replace a fan perform the following steps (see Figure 4.1):
1 Release the fan’s four screws and gently pull the unit out half way.
2 Wait until the fan stops rotating, then pull it out all the way.
3 Insert the replacement fan, ensuring that it is correctly aligned, and fasten the
four screws.
