High-Density Ethernet Fabrics for AI Data Centers.
N9164E-NS4-O provides 64 fixed 800G OSFP ports in a 2U data center switch for AI/ML leaf-and-spine fabrics. NVIDIA Spectrum-4 switching silicon supports Ethernet-based AI networking and web-scale spine deployments. The Cisco N9100 family supports NX-OS operation and the cloud-managed Nexus Hyperfabric operating model, allowing the management approach to be specified with the hardware order. This 64-port 800G fixed switch uses built-in fabric interfaces rather than removable uplink cards. The N9164E-NS4-O= spare chassis differs from the standard model by excluding power supplies and fans; those omissions matter when comparing otherwise similar hardware quotations.

Technical Details
102400 Gbps switching capacity provides the aggregate bandwidth for high-density fabric connections. 160 MB of fully shared on-die buffering supports congestion management, while Priority Flow Control and Explicit Congestion Notification provide mechanisms for lossless Ethernet transport. RoCE support addresses remote-memory traffic over the Ethernet fabric. N9164E-NS4-O carries 64 GB of system memory and a 240 GB SSD for system operation and local storage. A shared pool of 512000 forwarding entries serves routing, host, MAC, access-control, multipath, and tunnel functions rather than representing a dedicated MAC-table allocation. NX-OS programmability includes RESTCONF, NETCONF, gNMI, and a REST API for integration with automation systems. The switch also supports model-driven telemetry for network observation and Power on Auto Provisioning for initial configuration workflows.
Ordering
Order N9164E-NS4-O new sealed or certified refurbished, specifying the condition and complete hardware configuration on the purchase order. Refurbished units are inspected and bench-tested for power-on, POST, rated-speed port links, clean boot, PSU status, and fan status; firmware is verified and configurations are wiped to factory default. ORM provides up to a 3-year extended warranty on new units and up to 1 year on certified refurbished units, with 30-day returns on every condition, terms apply; Cisco's separate platform warranty is a 1-year limited hardware warranty. For enterprise and volume orders, submit the required quantities and accessories; POs are accepted, with Net-30 for government and RMA with advance replacement.

Best For
Mixed-Speed Fabric Refresh
When a fabric refresh must retain lower-speed connections, the fixed ports support 2x400G, 4x200G, or 4x100G breakout configurations. The breakout choice changes the connection plan without changing the chassis. Specify the required link speeds and match transceivers and cabling before issuing the purchase order.
Console-Based Staging
When switches must be configured before connection to the production network, initial setup starts through the serial console. The console defaults to 115200 baud, eight data bits, one stop bit, and no parity. Specify console access and prepare the management address and netmask before scheduling staging work.
Cooling Spare Inventory
When a maintenance order includes cooling spares, more than one failed fan tray causes a warning and shutdown within two minutes unless corrective action is taken. NXASFAN-190CFMPI is the supported port-side intake fan module. Include the required spare quantity and confirm access for replacement before releasing the purchase order.
Not Suitable If
Port-side exhaust airflow
Port-side intake is the only supported airflow direction. A deployment requiring port-side exhaust cannot use this chassis in that orientation.
A single rack unit
The chassis requires 2U of rack height. A cabinet allocation limited to one rack unit cannot accommodate this switch without changing the space allocation.

Questions & Answers
What does the N9164E-NS4-O part number identify?
N9164E-NS4-O identifies a Cisco N9100 fixed switch with 64 800G OSFP ports. The configuration uses NVIDIA Spectrum-4 switching silicon. The complete part number distinguishes the standard switch from the N9164E-NS4-O= spare chassis, which excludes power supplies and fans rather than identifying a different port configuration.
How is N9164E-NS4-O managed?
N9164E-NS4-O supports NX-OS CLI management, Cisco Nexus Dashboard automation, and the cloud-managed Nexus Hyperfabric operating model. Initial NX-OS configuration uses the serial console before network management is established. Programmable interfaces include RESTCONF, NETCONF, gNMI, and a REST API; specify the intended operating model before preparing configuration workflows.
What is the lifecycle status of N9164E-NS4-O?
Cisco has not announced an end-of-sale date for N9100. N9164E-NS4-O remains available to order. The hardware purchase should still identify the required software entitlement and support coverage separately, since current orderability does not establish the term or scope of an individual service contract.
What conditions and warranties does ORM Systems offer for N9164E-NS4-O?
ORM Systems offers N9164E-NS4-O new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Cisco's separate platform warranty is a 1-year limited hardware warranty. Both ORM conditions include 30-day returns, terms apply; refurbished managed units are inspected, bench-tested, firmware verified, and wiped to factory default.
Which licensing paths are available for N9164E-NS4-O?
N9164E-NS4-O supports XF3-class DCN Essentials, Advantage, and Premier subscriptions, with a three-year minimum term, plus perpetual Advantage licensing. Subscription terms include three, five, and seven years. N9100-DCN-AD-XF3 provides the perpetual Advantage path; perpetual licenses are not portable between devices, so hardware condition does not establish entitlement transferability.
What is the difference between N9164E-NS4-O and N9164E-NS4-O=?
N9164E-NS4-O= excludes power supplies and fans, while N9164E-NS4-O is the standard switch configuration. Both identify the same 64-port 800G OSFP switch. The standard configuration suits an assembled hardware order; the spare chassis suits replacement requirements where compatible PSU3KW-HVPI and NXASFAN-190CFMPI components are supplied separately.
Can the N9100 64-port 800G switch connect to lower-speed devices?
The N9100 64-port 800G switch supports 2x400G, 4x200G, and 4x100G breakout configurations. These options allow lower-speed connections through the OSFP interfaces rather than separate access-port modules. Match each intended connection to compatible transceivers and cabling, and specify the required breakout arrangement with the hardware order.
Does N9164E-NS4-O include redundant power supplies?
N9164E-NS4-O includes two PSU3KW-HVPI modules, with one for operation and one for redundancy. Each PSU3KW-HVPI is rated at 3000W and uses port-side intake airflow. Connect the two PSU3KW-HVPI modules to separate power sources when input-source redundancy is required, and match the power connection to the site supply.
Which rack installation kits fit the N9100 800G switch?
The N9100 800G switch supports NXK-ACC-KIT3-S and NXK-ACC-KIT3-L installation kits for four-post racks. The chassis occupies 2U and requires suitable cabinet depth, access, and airflow clearance. Specify the rack arrangement and mounting-rail spacing before selecting NXK-ACC-KIT3-S or NXK-ACC-KIT3-L for the purchase order.
Does N9164E-NS4-O need an FGLB add-on license for Spectrum-X adaptive routing?
N9164E-NS4-O does not require an FGLB add-on license for NVIDIA Spectrum-X adaptive routing; DCN Advantage licensing on all switches in the fabric is sufficient. This licensing distinction concerns the Spectrum-4-based switch. Specify the fabric-wide Advantage entitlement rather than assuming an additional FGLB license is necessary for this model.
