The Cisco Nexus 9364E-SG2-O switch (N9364E-SG2-O) is a 2-rack unit (RU), fixed-port, high-density switch designed to support high-density 800G fabrics for next generation leaf and spine designs. This switch contains Cisco Silicon One G200 which focuses specifically on enhanced Ethernet-based artificial intelligence/machine learning AI/ML and web-scale spine deployments. It is a 5 nm, 51.2 TeraBits per second (Tbps), 512 X 112 Gbps serializer-deserializer (SerDes) switch. This switch has these ports and capabilities:

• 64 OSFP (octal small form-factor pluggable) ports that provide high-speed interface connection to networking equipment

• 1 QSFP28 (quad small form-factor pluggable) Punt Injection Engine (PIE) port

Each OSFP port has its own bi-color (amber or green) LED that can be used to display the link status indication. For port LED status information, see Switch Chassis LEDs.

The G200 NPU (neural processing unit) and all 64 OSFP ports connect directly to the NPU. The maximum power provided to each OSFP port is 20W per instance.

This switch includes these user-replaceable components:

Fan modules (four) with one airflow choice: Port-side intake fan module (FAN-PI-V4)

Note	The switch functions normally when only one fan tray fails. If more than one fan tray fails, the switch issues a warning and powers down within two minutes unless you take corrective actions to replace the failed fan trays.

The switch has four, latched fan modules that install into the chassis from the rear. Fans cool the system and maintain proper airflow through the system. The fan modules work with N+1 redundancy.

Power supply modules (two—one for operations and one for redundancy [1+1]). The power supply module can be AC type ONLY. The option is: 3kW AC, PSU3KW-HVPI.

Note	All the fan modules and power supplies must use the same airflow direction. For this switch, the air flow direction is front-to-back.
