N9K-C93180LC-EX is a fixed, managed data center switch supporting alternative configurations of up to 32 40/50G connections or 18 100G connections. The Cisco N93180LC-EX Switch uses a 1U rack-mount chassis with built-in QSFP interfaces rather than a removable uplink card, and connected equipment receives no PoE. Base NX-OS software provides Layer 2 switching; additional entitlements enable advanced functions. Within the Cisco N9300-EX series, this model concentrates on higher-speed optical connectivity rather than the 48-port 1/10/25G server-facing arrangement of the discontinued N9K-C93180YC-EX. NX-OS mode supports conventional switch operation, while ACI mode provides policy-based systems management. Specify the operating mode and required port configuration together, because the advertised connection counts describe different configurations rather than ports available simultaneously.
N9K-C93180LC-EX price for new stock is $8,394.75, a 50% saving from the Cisco list price of $16,789.50. N9K-C93180LC-EX refurb price is $446.25. N9K-C93180LC-EX is in stock and available for next-day dispatch. (terms applied)

3600 Gbps switching capacity establishes the bandwidth envelope for aggregating optical connections. Over 2600 Mpps forwarding capacity provides a separate packet-processing figure when evaluating traffic profiles. A 40 MB system buffer accommodates queued traffic, while Approximate Fair Dropping distinguishes long-lived flows from shorter flows during congestion. N9K-C93180LC-EX contains 24 GB of system memory and a 64 GB SSD for system storage. CLI administration, JSON-based APIs, NETCONF and RESTCONF provide interactive and programmatic configuration paths; Cisco Data Center Network Manager supplies graphical network administration. Virtual Port-Channel supports Layer 2 multipathing, while appropriately licensed software supports BGP, OSPF, EIGRP and IP multicast routing. These licensed functions are separate from the base software feature set. 500W maximum input draw is the upper power figure for circuit planning, rather than the 220W typical draw. Select the power-input configuration and cooling direction to match the cabinet's electrical and airflow arrangement.
ORM Systems offers N9K-C93180LC-EX in new sealed and certified refurbished condition; refurbished units are inspected and bench-tested for power-on and POST, rated-speed port links, clean boot, optics bay recognition, PSU status and fan status, with firmware verified and configuration wiped to factory default. Specify condition, operating mode, software entitlements, supply configuration, airflow direction and required optics on the purchase order. ORM warranties are up to a 3-year extended warranty for new units and up to 1 year for certified refurbished units, with 30-day returns on every condition, terms apply; Cisco's original 1-year limited hardware warranty and service ended August 31, 2025. For enterprise and volume orders, POs are accepted, government buyers receive Net-30 terms, and RMA with advance replacement covers the UK, EU, US and MEA regions.

When an existing installation needs more 10G fiber connections without adding another switch, N9K-C93180LC-EX supports up to 72 connections through breakout cables. Port templates determine the usable arrangement. Specify the intended breakout layout, peer interface requirements and matching cable requirements before issuing the purchase order.
When a lab must reproduce an existing segmentation configuration, the N9300-EX VLAN allocation needs checking before the hardware order. Of 4096 VLAN identifiers, 127 are reserved. Compare the intended configuration with that reservation, then specify the required VLAN allocation and software image before issuing the purchase order.
Continuing Cisco service and security support
N9K-C93180LC-EX passed its last support date on August 31, 2025; Cisco service and security support have ended. Cisco Nexus 9336C-FX2 is its migration model.
More than eighteen native 100G connections
N9K-C93180LC-EX supports a maximum of 18 native 100G connections. N9K-C9336C-FX2 provides 36 40/100G QSFP28 ports and is the migration model for higher native port density.
Native RJ-45 access for server connections
N9K-C93180LC-EX uses QSFP interfaces for data connections and has no RJ-45 access ports. Its RJ-45 management interface does not provide a native copper server connection.

N9K identifies the Nexus 9K family in N9K-C93180LC-EX; C93180LC identifies the fixed model with selectable 40/50G or 100G connectivity; EX identifies the N9300-EX series. The complete PID denotes up to 32 40/50G connections or 18 100G connections, not 180 access ports.
N9K-C93180LC-EX is managed through the NX-OS CLI, serial console and JSON-based APIs, with NETCONF and RESTCONF programmability and Cisco Data Center Network Manager providing graphical network administration. ACI mode provides policy-based systems management instead. Specify the intended operating mode and management integration when preparing the hardware and software order.
N9K-C93180LC-EX is discontinued and no longer supported by Cisco: end of sale was August 30, 2020, and the last date of support was August 31, 2025. Software maintenance ended August 30, 2021. Cisco Nexus 9336C-FX2 is the migration model for replacement planning.
ORM Systems offers N9K-C93180LC-EX new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Returns are 30 days for either condition; terms apply. Cisco's original 1-year limited hardware warranty and Cisco service ended August 31, 2025. Refurbished managed units are firmware verified and wiped to factory default.
N9K-C93180LC-EX supports DCN Essentials and Advantage subscriptions starting at three years, plus perpetual Advantage licenses for NX-OS or DCN. Essentials perpetual licenses are no longer sold. Base software includes Layer 2 security and management, while advanced functions require separate entitlements. Specify the licensing path independently of new or refurbished hardware condition.
N9K-C93180LC-EX supports up to 32 40/50G QSFP+ connections or 18 100G QSFP28 connections, depending on the selected port configuration. Breakout cables can provide up to 72 10G connections. These are alternative template-driven configurations rather than simultaneous port totals, so specify the required link mix and breakout arrangement before ordering.
The Cisco N93180LC-EX Switch accommodates two power supplies, with NXA-PDC-930W-PI and NXA-PDC-930W-PE providing DC options and N9K-PUV-1200W providing universal high-voltage AC/DC operation. Specify supply type, quantity and cooling direction on the purchase order rather than assuming that a particular supply pair accompanies the chassis.
BGP, OSPF and EIGRP are available on N9K-C93180LC-EX with the appropriate additional software entitlement, rather than being included in its base Layer 2 feature set. Licensed functions also include IP multicast routing. Confirm the ordered license and software release against the intended routing design; hardware capability alone does not establish entitlement.
The Cisco N93180LC-EX Switch is a 1U rack-mount data center switch, measuring 44 mm high, 439 mm wide and 571 mm deep. NXK-ACC-KIT-1RU provides the four-post rack-mount accessory kit. Specify mounting hardware on the purchase order and allow sufficient chassis depth and cable clearance in the cabinet.
3600 Gbps switching capacity and over 2600 Mpps forwarding capacity define the N9K-C93180LC-EX bandwidth and packet-processing envelope. A 40 MB system buffer holds queued traffic. Evaluate the intended traffic profile alongside port configuration and congestion behavior; switching capacity alone does not describe packet rate or buffering requirements.
N9K-C93180LC-EX provides native 40/50G or 100G connectivity, whereas N9K-C93180YC-EX provides 48 native 1/10/25G fiber connections. Both models are discontinued. The LC model matches existing higher-speed optical connection plans; the YC model matches legacy 25G server-access requirements. These roles describe legacy hardware comparisons rather than current migration choices.
N9K-C93180LC-EX uses QSFP interfaces for data connections, while N9K-C93108TC-EX provides 48 native 100M/1/10GBASE-T copper connections. Both models are discontinued. Existing optical aggregation requirements distinguish the LC model from the TC model's copper server-access role; the required connection medium determines which legacy configuration matches an installation.
N9K-C93180LC-EX supports up to 18 native 100G connections, whereas N9K-C9336C-FX2 provides 36 40/100G QSFP28 ports. N9K-C93180LC-EX is discontinued and past Cisco support. The LC model matches existing legacy configurations; the FX2 migration model suits buyers requiring a higher native 100G connection count.
