N3K-C3048TP-1GE

N3K-C3048TP-1GE connects 48 copper Gigabit Ethernet endpoints through fixed downlinks and provides four built-in 10G SFP+ uplinks. This managed, non-PoE top-of-rack switch runs NX-OS with a default Layer 2 feature set. The Nexus 3048 belongs to the Cisco Nexus 3000 family and uses a 1U chassis with dual-supply redundancy. A dedicated management connection keeps out-of-band administration separate from server-facing traffic, while the uplinks occupy fixed cages rather than a removable network card. The discontinued N3K-C3048-1PS differs by providing a single-supply configuration. For an existing rack replacement, the purchase decision therefore includes the supplied power configuration and installed software entitlements, not just the matching chassis identifier.

176 Gbps switching capacity and 132 Mpps forwarding support line-rate traffic handling across the Ethernet interfaces. 124W maximum power draw provides the electrical sizing figure rather than the rating printed on a compatible power module. A 128000-entry MAC table supports address learning, while the shared 9 MB packet buffer holds queued traffic. N3K-C3048TP-1GE provides 2 GB of boot flash for its operating image. LACP supports link aggregation, and RSTP and MSTP provide loop-control options. vPC supplies Layer 2 multipathing without creating a hardware stack. Keep the switching configuration, management access and licensed routing functions distinct when preparing an existing configuration for a replacement chassis.

N3K-C3048TP-1GE is offered new sealed and certified refurbished; refurbished units are inspected and bench-tested for power-on and POST, rated-speed port links, optics bay recognition, PSU status, fan status and clean boot, with firmware verified and configuration wiped to factory default. Specify the required condition and included hardware on the purchase order before confirming quantities. New hardware carries up to a 3-year extended ORM warranty, certified refurbished hardware carries up to 1 year, and every condition has 30-day returns; terms apply, while Cisco coverage ended August 31, 2025. Enterprise and volume orders accept POs, government purchases can use Net-30, and RMA with advance replacement is available.
