Overview of the Cisco Nexus 9408 Switch
The Cisco Nexus 9408 (N9K-C9408) is a 4 rack unit (RU) 8-slot modular chassis switch, which is configurable
with up to 128 200-Gigabit QSFP56 (256 100-Gigabit by breakout) ports or 64 400-Gigabit ports. This switch
supports port-side intake airflow. The switch requires four AC power supplies for operation, and offers 2+2
power grid redundancy.
This switch includes the following high power optics and MACsec:
• The N9K-X9400-16W LEM offers full MACsec (128 ports) for a full load chassis with no limitation for
200G optics.
• The N9K-X9400-8D LEM offers full MACsec (64 ports) for a full load chassis but with a limit of 400G
high power optics within 32pcs among 8 slots (maximum of 32 ports of 20-W optics irrespective of
MACsec), and the high power optics can go in any of the 400G ports.
The following figure shows the fan-side chassis features that you use when installing the chassis or replacing
its modules.
