Cisco CBS350-12XT 12-Port 10G Managed L3 Switch 240Gbps SFP+

The Cisco CBS350-12XT (CBS350-12XT-NA-RF) is a 10 Gigabit Layer 3 managed switch from the Cisco Business 350 Series, built for small business, SMB, retail, and campus deployments that need high-bandwidth aggregation in a compact 1U chassis. It provides 10 dedicated 10GBase-T RJ-45 ports plus 2 combo 10G SFP+/RJ-45 ports (12 total) with 240 Gbps wire-speed switching capacity, static IPv4/IPv6 Layer 3 routing, and simple management through the Cisco Business Dashboard and mobile app. Sold as Cisco Refresh — Cisco's official program for genuine remanufactured equipment, restored to like-new condition by Cisco itself.

• Port Layout (Read Carefully): 10x dedicated 10GBase-T RJ-45 ports plus 2x combo 10G SFP+/RJ-45 ports — 12 ports total. The 2 combo ports operate as either RJ-45 OR SFP+ (one media type per port at a time, not both simultaneously)
• 240 Gbps Wire-Speed Switching: Cisco-datasheet-confirmed 240 Gbps switching capacity and 178.56 Mpps forwarding rate — all switches in the CBS350 series are rated wire-speed and non-blocking by Cisco
• Static Layer 3 Routing & Inter-VLAN: Static IPv4/IPv6 routing, Policy-Based Routing (PBR), DHCP relay, and inter-VLAN routing let you segment workloads across VLANs. Note: dynamic routing protocols such as OSPF and BGP are not supported — this is a static-routing SMB switch
• Stacking up to 4 Units: Configure up to 4 stacked CBS350 switches as a single management unit with one IP address; supports cross-stack VLANs, LAGs, and port mirroring within the CBS350 series
• Security & QoS: IEEE 802.1X, ACLs (1,024 rules), DHCP snooping, Dynamic ARP Inspection, IP Source Guard, IPv6 First Hop Security, plus 8 hardware QoS queues with DSCP/CoS prioritization
• Cisco Business Dashboard & Mobile App: Manage via Web GUI, Cisco Business mobile app, SNMP v1/v2c/v3, SSH, or CLI; supports Cisco Network Plug and Play for zero-touch deployment
• Energy Efficient 1U Design: IEEE 802.3az Energy Efficient Ethernet reduces operating cost; sleek 1U rack-mountable chassis (mounting brackets included) with low 64.10 W typical power draw

• PoE: None (non-PoE model)
• Power: Internal AC 100–240V, 50/60 Hz • 64.10 W typical • IEEE 802.3az EEE
• Dimensions: 17.32" x 7.99" x 1.73" (440 x 203 x 44 mm) • Weight: 6.46 lb (2.93 kg)
• Form Factor: 1U Rack-mountable (brackets included)
• Condition: Cisco Refresh (RF) — Cisco-remanufactured to like-new condition

• What does "Cisco Refresh" mean?
  Cisco Refresh is Cisco's official certified remanufactured equipment program. Each unit is genuine pre-owned Cisco equipment remanufactured to like-new condition by Cisco itself, with critical engineering change orders applied and full functional testing performed. This is different from third-party refurbishment.
• Does this switch support PoE, OSPF, or BGP?
  No to all three. The CBS350-12XT is a non-PoE 10G aggregation switch and supports only static IPv4/IPv6 routing at Layer 3. If you need PoE, look at CBS350-NGP or CBS350-MGP variants. If you need OSPF or BGP, you'll need a Cisco Catalyst-class switch.
• How do the 2 combo ports work?
  The 2 combo ports support either 10GBase-T (RJ-45) or 10G SFP+ (fiber/DAC/AOC) — one media type per port at a time, not both simultaneously. Compatible with Cisco 1G/10G SFP and SFP+ transceivers, plus DAC and AOC cables.
• Will this work outside North America?
  This is the North America SKU (-NA) shipping with a US-style power cord. The internal power supply is universal 100–240V, 50/60 Hz, so the unit will operate on international mains voltage with a region-appropriate IEC C13 power cable or plug adapter.
