Figure 2: Node Processor Configuration Switch Settings
For normal run mode all DIP switches on SW2 must be in the OFF position.
Bootloader mode - set DIP switch SW2-1 or SW2-3 to the on position.
Cabling
The top port of the Node Processor is dedicated to host communications.
Redundant host communication ports of Node Processors can be connected to one or more Ethernet
networks (shown in Figure 3 with Switch 1and Switch 2 respectively).
Non-Redundant node processor configurations use port B for redundant host communications.
Redundant node processors use port B for inter-processor and I/O communications (as needed if
redundant chassis processors are configured) as shown in Figure 3 with Switch B. If redundant chassis
processors are not used, the port still should be connected to I/O Switch B.
The C and D ports of the node processor are always dedicated to I/O communications.
The node processor uses the I/O ports to communicate with I/O ports on the chassis processor, in effect
creating I/O Path B, I/O Path C and I/O Path D (shown in Figure 3 with Switch B, Switch C and Switch D
respectively).
Refer to Table 1 for a summary of Ethernet cabling.
