Network configuration

Only the LAN devices connected to the HNC must be configured.

LAN devices are generated on the HNC as devices with the device type code 6D.

The LAN connection is generated in BCAM, see the “BCAM” manual [11].

The BS2000 devices for the control LAN (MCNPR, see the “Operation and Administration” manual [5]) are also connected to the HNC.
By default the device pairs for the control LAN are configured with the LUNs 0040/0041 (MN CC40/CC41) through 005E/005F (MN CC5E/CC5F) on the HNC.
For the redundant control LAN, the device pairs are configured with the LUNs 0040/0041 (MN CD40/CD41) through 005E/005F (MN CD5E/CD5F).
