Line Card Overview
Cisco Nexus 9800 switches support the following line cards:
Table 2: Supported Line Cards and Transceivers
TransceiversLine Card PIDs
QSFP-DD / QSFP28 / QSFP+N9K-X9836DM-A
QSFP-DD / QSFP28 / QSFP+N9K-X98900CD-A
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.
Note
Supervisor Module Overview
Cisco Nexus 9800 Supervisor Modules (N9K-C9800-SUP-A) manage all control plane functions on the Cisco
Nexus 9800 Series Switches.

Fabric Module Overview
Cisco Nexus 9808 switches support the following fabric modules:
• N9K-C9808-FM-A—Cisco Nexus 9808 Fabric Module
Temperature and Physical Specifications
For temperature and physical specifications, refer to the Physical characteristics table in the Cisco Nexus
9800 Series Switches Data Sheet.
Weight and Power Consumption
For weight and power consumption, refer to the Physical characteristics table in the Cisco Nexus 9800 Series
Switches Data Sheet.
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.
