    Line Card Overview

    Cisco Nexus 9800 switches support the following line cards:

    Table 2. Supported Line Cards and Transceivers

    Line Card PIDs

    Transceivers

    N9K-X9836DM-A

    QSFP-DD / QSFP28 / QSFP+

    N9K-X98900CD-A

    QSFP-DD / QSFP28 / QSFP+

    Note

    When unlocking the ejector button and then relocking it without removing the line card, the line card will power down. The line card will not power up and will not show poweroff module in command line interface. Preforming OIR is required to power up the line card.

    Supervisor Module Overview

    Cisco Nexus 9800 Supervisor Modules (N9K-C9800-SUP-A) manage all control plane functions on the Cisco Nexus 9800 Series Switches.

    Airflow Direction

    To ensure proper airflow for the switch in your facility, position the switch with its air intake on a cold aisle and the air exhaust on a hot aisle.

    Maximum Power Available to the Switch

    The maximum power available for operations depends on the input power from your power source, the number and output capabilities of your power supplies, and the power redundancy mode that you use.

    The following table lists the amount of power available for Cisco 9800 series switches from all available power trays.
