Replacing the NVM on MXC300 Cards
This section provides replacement instructions for the NVM.

AUTION
:
To prevent disruption of data stored on the NVM,
make sure you do not open the NVM cover while the
MXC300 accesses the NVM. Before attempting to remove
the NVM, monitor the NVM (yellow) indicator; open the
NVM cover only after the NVM indicator on the MXC300
has been off for at least 2 minutes.
To replace the NVM:
1.
Force switch to the other MXC300.
2.
Wait until the NVM (yellow) indicator of the MXC300 on which the NVM
is to be replaced turns off, and remains off for at least 2 minutes.
3.
Open the two captive screws fastening the NVM cover to the MXC300.
4.
Press the NVM release pushbutton, using the NVM cover's edge as an
extractor tool.
5.
Carefully extract the NVM from the MXC300.
6.
Orient the replacement NVM in the correct position and push it straight
into its socket.
7.
Replace the NVM's cover, and fasten it to the MXC300 with its two captive
screws.
At this stage, you may either wait for the automatic updating of the database
stored on the new NVM (this may take up to one hour), or immediately force a
switching to the MXC300 on which the NVM has been replaced.
