Cisco SX550X-12F-K9-EU - Stackable Managed Layer 3 Switch, Black

The Cisco SX550X-12F-K9-EU is a 12-port 10G SFP+ stackable managed Layer 3 switch designed for business network backbones. This non-PoE model features 12 SFP+ slots for 10-Gigabit fiber connections, alongside two additional combo 10G ports. It delivers a total switching capacity of 240 Gbit/s and a forwarding throughput of 178.56 Mpps, handling traffic across campus access layers or branch office deployments. The hardware supports full IPv4 and IPv6 routing with up to 7,168 static routing entries.

The rack-mountable switch is housed in a black chassis that fits standard 19-inch cabinets, measuring 440 by 257 by 44 mm. Up to eight units can be stacked to function as a single logical entity. The device uses a 1.3 GHz dual-core processor and 512 MB of memory. Configuration is handled through a web-based GUI, a command-line interface (CLI), or SNMP. Four internal fans regulate the temperature, with an operating noise level of 45.8 dB. The switch supports up to 4,000 active VLANs for network segmentation.

• Access control lists support up to 3,000 rules for traffic management and security.
• A 32,000-entry MAC address table and 3 MB packet buffer accommodate high-density device environments.
• Support for a redundant power supply (RPS) helps maintain uptime during power failures.
• Quality of Service (QoS) uses Strict Priority and Weighted Round-Robin scheduling to prioritize critical data.
• Mean time between failures (MTBF) of 652,253 hours.
