All-Port MACsec Hardware for Data Center Fabrics

N9K-C9348D-GX2A provides MACsec-capable hardware across all 48 fixed 400G QSFP-DD ports, with two additional fixed 10G SFP+ interfaces. The N9300-GX2 switch occupies 2U and serves data center leaf-and-spine fabrics rather than powered copper endpoint access. NX-OS provides static routing in the base configuration; licensed dynamic routing extends that configuration for routed fabrics. N9K-C9364D-GX2A increases native 400G port density to 64, but its MACsec hardware covers only the first 16 ports. Cisco ACI leaf and spine modes provide alternative operating choices. Specify the operating mode separately from the hardware identifier, which does not establish a bundled software tier.

N9K-C9348D-GX2A price is $253,177.53. N9K-C9348D-GX2A is in stock and available for next-day dispatch. (terms applied)

Technical Details

38400 Gbps switching capacity and an 8350 Mpps forwarding rate provide the throughput figures for fabric sizing. A 120 MB packet buffer accommodates queued traffic, while 32 GB of system memory supports switch operation. N9K-C9348D-GX2A also carries a 128 GB SSD; that storage figure is separate from DRAM. The Cisco N9000 family supports vPC for Layer 2 multipathing and 128-way ECMP for appropriately licensed routed designs. BGP, OSPF, IS-IS, and EIGRP require routing entitlements rather than being implied by the chassis identifier. Maximum draw of 3124W sets the facility power provision for peak operation, not the rating of an individual supply. The chassis-only weight excludes installed power supplies and fans, which must be considered when planning handling.

Ordering

N9K-C9348D-GX2A is offered new sealed or certified refurbished; 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 either condition, terms apply. Refurbished units are inspected and bench-tested for power-on and POST, clean boot, rated-speed links on every port, and optics bay recognition. Specify condition, software entitlements, pluggables, and airflow on the PO. Enterprise and volume orders accept POs, government Net-30, and RMA with advance replacement, with regional stock and RMA coverage across the UK, EU, US, and MEA.

Buying Notes

Buying NotesKey Specs

Software requires separate selection

Order software separately: N9K-C9348D-GX2A supports DCN Essentials, Advantage, or Premier subscriptions starting at three years, plus DCN ACI+NX-OS Advantage or NX-OS Advantage perpetual licenses. A security add-on is mandatory.

Optical links require pluggables

Order compatible pluggables with N9K-C9348D-GX2A rather than treating optical cages as complete links. Confirm each optic's required software release and specify NXA-ACC-QDD-DC dust covers for unused ports.

Refurbished configuration starts clean

Certified refurbished N9K-C9348D-GX2A units have firmware verified and configurations wiped to factory default. Include a deployment configuration and appropriate software entitlements in the order plan rather than expecting a retained configuration.

Fabric Link Migration

During a fabric refresh that retains lower-speed connections, native 200G and 40G operation plus 4 x 100G or 2 x 200G breakouts allow different link modes within the port plan. Record the intended mode for each connection, then specify compatible pluggables and the required software release before the PO.

Rack Integration Planning

Where an existing cabinet must accept a new fabric switch, the NXK-ACC-KIT2-2RU mounting kit uses a four-post rack arrangement. Confirm front and rear mounting posts, rail engagement, aisle orientation, and installation access before allocating equipment. Verify NXK-ACC-KIT2-2RU inclusion and the required installation hardware before the PO.

Initial Configuration Staging

During lab staging before fabric installation, initial console access establishes the management address and netmask. The setup requires a password of at least eight characters. Reserve the out-of-band connection, arrange CAB-CONSOLE-RJ45 console access, and include the addressing and credential plan in the staging requirements before the PO.

Not Suitable If

Single rack-unit installation

The chassis occupies 2U. N9K-C9332D-GX2B uses 1U but reduces native 400G density to 32 ports and limits MACsec-capable hardware to the last eight ports.

More than 48 native 400G connections

The chassis provides 48 native 400G ports. N9K-C9364D-GX2A provides 64, but only its first 16 ports support MACsec hardware, changing encryption coverage alongside connection density.

Questions & Answers

What does the N9K-C9348D-GX2A part number identify?

N9K-C9348D-GX2A identifies the Cisco N9348D-GX2A configuration with 48 400/100G QSFP-DD ports and two 1/10G SFP+ ports. GX2A is part of the complete model designation, not a selected DCN license tier. Put the exact hardware PID and separately selected software entitlements on the PO.

How is N9K-C9348D-GX2A managed?

N9K-C9348D-GX2A supports console and network CLI management, REST APIs, RESTCONF, NETCONF, gNMI, and Cisco Nexus Dashboard integration. Cisco ACI provides a separate centralized operating mode. Only one out-of-band management port can be active; specify the operating mode, entitlement, and management connection before ordering.

What is the lifecycle status of N9300-GX2?

Cisco has not announced an end-of-sale date for N9300-GX2. N9K-C9348D-GX2A supports NX-OS and Cisco ACI deployment choices. Keep hardware lifecycle planning separate from software selection: operating-mode support and license duration are separate purchase decisions, not an announced hardware retirement milestone or a dated replacement requirement.

Which licensing options apply to N9K-C9348D-GX2A?

N9K-C9348D-GX2A supports DCN Essentials, Advantage, or Premier subscriptions for 3, 5, or 7 years, plus perpetual DCN ACI+NX-OS Advantage and NX-OS Advantage licenses. A security add-on is mandatory. Manage entitlements through a Cisco Smart Account; perpetual licenses are device-bound, and expiring add-ons require renewal or deactivation followed by a reload.

Does N9K-C9348D-GX2A support MACsec on every 400G port?

N9K-C9348D-GX2A provides wire-rate MACsec-capable hardware on all 48 QSFP-DD ports. A security add-on license is mandatory for this hardware configuration; encryption is not an unlicensed inclusion. Verify that the security entitlement and chosen operating mode are included on the PO rather than assuming the bare hardware PID grants encryption rights.

Which routing features are included with N9K-C9348D-GX2A?

N9K-C9348D-GX2A supports static routes, SVIs, and HSRP without an additional routing license. BGP, OSPF, IS-IS, and EIGRP require appropriate licensed routing capabilities. The hardware supports 1000000 IPv4 LPM routes; that forwarding-table limit is separate from the entitlement required to use a dynamic routing protocol.

Which power supplies can the Cisco N9348D-GX2A use?

Cisco N9348D-GX2A uses two matching power supplies in a 1+1 arrangement. NXA-PAC-3200W-PI supports AC/HVDC input, NXA-PDC-3200W-PI supports DC/HVDC input, and NXA-PAC-3200-PE provides port-side exhaust AC input. Do not mix AC and DC supplies. Connect the pair to separate power sources and match airflow across installed modules.

How much rack space does N9K-C9348D-GX2A require?

N9K-C9348D-GX2A occupies 2U and uses the NXK-ACC-KIT2-2RU mounting kit. The chassis measures 87.6 mm high, 442.3 mm wide, and 757.6 mm deep. Its 23.2 kg chassis weight excludes power supplies and fans, so plan handling and rack support for the complete installed configuration.

What is the difference between N9K-C9348D-GX2A and N9K-C9364D-GX2A?

N9K-C9348D-GX2A has 48 native 400G QSFP-DD ports, while N9K-C9364D-GX2A has 64. Both belong to the N9300-GX2 family. Choose the 48-port model when that connection count meets the port plan; specify the 64-port model when the purchase requires more native high-speed connections.

What is the difference between N9K-C9348D-GX2A and N9K-C9332D-GX2B?

N9K-C9348D-GX2A provides MACsec-capable hardware on every QSFP-DD port, whereas N9K-C9332D-GX2B restricts MACsec-capable hardware to the last eight ports. Map encrypted connections before selecting a chassis. The former suits all-port encryption requirements; the latter suits deployments with a defined subset of links requiring hardware encryption.

What is the difference between N9K-C9348D-GX2A and N9K-C9332D-GX2B-M?

N9K-C9348D-GX2A has 32 GB of system memory, while N9K-C9332D-GX2B-M has 64 GB. Memory capacity does not select a software tier or establish an entitlement. The former meets a 32 GB memory requirement; the latter is the memory variant when 64 GB is explicitly required.

Which conditions and warranties does ORM offer for N9K-C9348D-GX2A?

ORM offers N9K-C9348D-GX2A new sealed with up to a 3-year extended warranty or certified refurbished with up to a 1-year warranty. Cisco's hardware warranty is a separate 1-year limited term. Both ORM conditions have 30-day returns, terms apply; refurbished units are inspected, bench-tested, firmware verified, and wiped to factory default.
