A 3m or longer QSFP cable and a 5m or longer management cable are required between the FE, and the CE#1
in the first expansion rack (or Expansion Rack#0) and CE#2 in the second expansion rack (or Expansion
Rack#1).
• A 10m or longer cable is required between the FE and the CE#3 in the third expansion rack (or Expansion
Rack#2).
