WARNING: When working with optical fibres, follow all the warning labels and always wear eyeprotection. Never look directly into the end of a terminated or unterminated fibre or connectoras 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 beinginserted incorrectly.2. Insert the optic into the port until it gently snaps into place.Port Numbering ConventionOn the switch, all ports operate by default in 40GbE mode. If you use a breakout cable, each port canoperate in 4x10GbE mode.Ports are located on three line cards as shown below. The line cards are factory-installed and are nothot-swappable or field-replaceable. On each line card, the fixed 40GbE ports are numbered from bottomto top in multiples of four, starting with zero; for example, 0, 4, 8, 12, and so on. When a breakout cable isinstalled, the resulting four 10GbE ports are numbered with the remaining numbers. For example, 40GbEport 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 0to 191.Figure 14. Port NumberingSplitting QSFP+ Ports to SFP+ PortsThe system supports splitting a single 40GbE QSFP+ port into four 10GbE SFP+ ports using one of thesupported breakout cables.For a list of supported optics, contact your Dell Networking representative or reseller.• Configure the system to recognize the port mode change.CONFIGURATION modelinecard number port number portmode quad– port - Enter the port number of the 40GbE port to be split.
