Note: If your server comes with two SMP Expansion Modules, the SMP
Expansion cables are included with the server. If you purchased a
second SMP Expansion Module separately, the cables are included with
the option.
2. Connect one end of the first cable to port 1 of SMP Expansion Module 0; then,
connect the opposite end of the cable to port 1 of SMP Expansion Module 1.
3. Connect one end of the second SMP Expansion cable to port 2 of SMP
Expansion Module 0; then, connect the opposite end of the cable to port 2 of
SMP Expansion Module 1.
Notes:
1. When multiple cables are connected between the SMP Expansion Module ports,
SMP data is interleaved between the cables for better performance.
2. The SMP Expansion cables are not redundant.
3. If either of the two cables is removed or fails, the server will either turn off or
restart, depending on your configuration.
4. The server will start and operate with one cable attached between the two SMP
Expansion Modules.
16-way SMP Expansion port cabling (models 1VX, 2VX, 3VX only): Use the
following illustration and tables to verify that the SMP Expansion cables are properly
connected.
