6. Redundancy with NX3030 CPU
307
When configured in conjunction with the NIC Teaming redundancy, failure is considered vital
failure, when a fault occurs in NET1 and NET2 interfaces.
NX5001 Modules Configuration
Insertion or Removal of NX5001 modules
NX5001 modules can be inserted or removed from the half-cluster rack. To execute this operation
correctly, one must be aware of the following rules:
ï‚· The number of NX5001 modules in each half-cluster may vary between zero and four
ï‚· It can be defined up to 4 simple PROFIBUS networks or 2 redundant PROFIBUS networks,
respecting the limit of 4 PROFIBUS Master NX5001 modules in each half-cluster
ï‚· When a PROFIBUS network is simple, it needs a single NX5001 module in each half-cluster.
When it’s redundant, it needs 2 NX5001 modules in each half-cluster
ï‚· Two NX5001 modules used to form a redundant PROFIBUS network must occupy side by side
positions in the rack
ï‚· The NX5001 modules quantity in the rack must be compatible with the number of existent
PROFIBUS networks and with the redundancy attribute of each network, on other words:
o 0 x NX5001: No PROFIBUS network
o 1 x NX5001: One simple PROFIBUS network
o 2 x NX5001: In this case there are two options:
 Two simple PROFIBUS network
 One redundant PROFIBUS network
o 3 x NX5001: In this case there are two options:
 Three simple PROFIBUS networks
 One redundant PROFIBUS network and one simple PROFIBUS network
o 4 x NX5001: In this case there are three options:
 Four simple PROFIBUS networks
 One redundant PROFIBUS network and two simple PROFIBUS networks
 Two redundant PROFIBUS networks
After inserting or removing the NX5001 modules, the configuration of the NX5001 modules
remaining in the rack must be checked.
NX5001 Modules Parameters Adjust
Each NX5001 module used in a simple PROFIBUS network, or each redundant pair of NX5001 used
in a redundant PROFIBUS network, has the following parameters to be adjusted.
