Cisco Catalyst 9300-48S-A - 48-port managed Layer 3 SFP switch, grey

The Cisco Catalyst 9300-48S-A 48-port managed Layer 3 SFP switch provides high-density fiber access for campus and branch networks. It uses fiber connections exclusively, offering 48 SFP module slots instead of standard RJ-45 copper ports. This configuration supports a switching capacity of 256 Gbit/s and a 190.47 Mpps forwarding rate. As a dedicated aggregation and distribution unit, this non-PoE model is designed for network routing rather than device power delivery. Integrated AES-256 MACsec hardware encrypts link traffic to secure data across the infrastructure.

The rack-mountable chassis fits into standard network cabinets. Administrators can deploy this Layer 3 device in a stackable configuration, managing multiple connected units as a single unified system. Extensive virtual LAN capabilities support up to 4,000 active VLANs for traffic segmentation. Built-in control functions use access control lists, DHCP snooping, and quality of service protocols to prioritise critical data streams. Furthermore, the unit performs static and IP routing to direct internal traffic between subnets without requiring an external router.

• Maintains a MAC address table of up to 32,000 entries for complex, multi-endpoint network environments.
• Supports jumbo frames of up to 9,198 bytes, improving transmission efficiency for large file transfers.
• Features IGMP snooping and multicast support to direct bandwidth-intensive streams only to requesting ports.
• Secures remote management sessions using integrated SSH and SSL cryptographic protocols.
• Engineered for long-term hardware reliability with a mean time between failures (MTBF) of 281,920 hours.
