2.1.6.4 Communication port
Figure 2-26 Communication Port
- This port provides communication path between H-FEM-H-x and H-SCM through backboard of H-SRU.
- +24V DC is provided through this communication port from backboard of H-SRU.
- H-FEM-H-x acquires ID information such as Rack ID, Sub rack ID and Slot ID through this communication
port. The IP address of H-FEM-H-x is assigned automatically using the acquired ID information.
