3-44 Hardware installation: Application Module (SNN/SNN-E)
553-4001-111 Standard 1.0 March 1997
Hardware upgrades and replacements
As your operation and needs grow, so may your need to expand the system.
You can add MVME332XTS/XT eight-channel asynchronous boards to the
Meridian MAX, provided that the maximum capacity for the system is not
exceeded. With each additional MVME332XTS/XT card, the number of
available ports increases by increments of eight.
The SNN/SNN-E hardware platform can support between 8 and 40 ports.
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.
CAUTION
Risk of equipment damage
Use an antistatic wrist strap before you remove
components from an antistatic bag. Failure to do so
can result in damage to components.
CAUTION
Risk of data corruption
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 “Meridian MAX power-down procedure”
chapter for more information.
