Hardware upgrades and replacements

As your operation and needs grow, so may your need to expand the system.
You can add MVME332XT eight-channel asynchronous boards to the NAC
system, providing the maximum capacity for the system is not exceeded.
With each additional MVME332XT board, the number of available ports
increases by increments of eight.
The NAC 2 hardware platform can support between 8 and 40 ports, or one
to five boards.
It is less likely that you may need to replace a component of the system. If
this is required, the upgrade instructions given in this section permit you to
make the replacement.
Note: All upgrades and replacements must be performed by qualified
technicians.
WARNING
Static sensitive devices
Use an anti-static wrist strap before you
remove components from an antistatic bag. Failure
to do so can result in damage to components.
CAUTION
Shut down the system from the
maintenance menu, then secure the system
before powering down the module
If you are adding a module to your system power,
down the column. Once the appropriate equipment
is powered down, remove the column's faceplate
and back plate for the appropriate shelf.
See the "NAC 2 power-down procedure" chapter
for more information.
