Port Numbering Convention; Splitting Qsfp+ Ports To Sfp+ Ports - Dell Z9500 Installation Manual

WARNING: When working with optical fibres, follow all the warning labels and always wear eye
protection. Never look directly into the end of a terminated or unterminated fibre or connector
as it may cause eye damage.
1. Position the optic so it is in the correct position. The optic has a key that prevents it from being
inserted incorrectly.
2. Insert the optic into the port until it gently snaps into place.

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.

Splitting QSFP+ Ports to SFP+ Ports

The system supports splitting a single 40GbE QSFP+ port into four 10GbE SFP+ ports using one of the
supported breakout cables.
