Port Numbering Convention
On the switch, all ports operate by default in 40GbE mode. If you use a breakout cable, each port can operate in 4x10GbE mode.
Ports are located on three line cards as shown below. The line cards are factory-installed and are not hot-swappable or field-
replaceable. On each line card, the fixed 40GbE ports are numbered from bottom to top in multiples of four, starting with zero;
for example, 0, 4, 8, 12, and so on. When a breakout cable is installed, the resulting four 10GbE ports are numbered with the
remaining numbers. For example, 40GbE port 0 contains 10GbE ports 0, 1, 2, and 3; 40GbE port 4 contains 10GbE ports 4, 5, 6,
and 7.
Line card 0 consists of ports 0 to 143; line card 1 consists of ports 0 to 191; line card 2 consists of ports 0 to 191.
