Removing an M-SPV/M-SPX

To remove an M-SPV/M-SPX perform the following steps:
1

Release the two retaining screws, one at the top and one at the bottom of the
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.
