A reverse-lookup mapping of the switch chip and port to CXP connector and its link LEDs is provided in the following table. The connectors and LEDs are given as connectorletter-location, where:
connector – The identifying number of the connector group (0–11).
letter – The letter identifying the upper (A) or lower (B) connector.
location – The location of the LED, left, center, or right.
Note - The shaded cell seen in the PDF file is used for the example described in Signal Route Through the Switch. The shaded cell is not seen in the HTML file.

Note - When using CXP to QSFP splitter cables, the P1, P2, and P3 QSFP connectors are related to the right, center, and left link LEDs respectively.
