Cisco Catalyst 9300L-48P-4X-E - Managed Switch, Grey

The Cisco Catalyst 9300L-48P-4X-E is a 48-port Layer 2 and Layer 3 switch designed for high-density enterprise networks. It provides 48 Gigabit Ethernet RJ-45 ports for downstream connections. With a 320 Gbit/s switching capacity, the device manages high-volume data traffic. Four SFP+ slots provide 10G uplinks for fibre connections to core switches or server infrastructure. The switch handles a forwarding rate of 176 Mpps, maintaining consistent throughput during peak loads.

This 1U rack-mountable switch provides a total PoE budget of 1440 W across its 48 ports, supporting equipment such as wireless access points and VoIP hardware. Network administrators can configure the system via web-based interfaces, a command-line interface, or a cloud-management platform. Built-in routing protocols, including OSPF and BGP, support up to 4,000 active VLANs for traffic segmentation. Support for redundant power supplies and the ability to stack up to eight units allow the system to scale alongside infrastructure demands.

• 32,000-entry MAC address table to support large local area networks and numerous connected endpoints.
• Support for jumbo frames up to 9,198 bytes, reducing packet overhead during large file transfers.
• Integrated access control lists (ACLs) and DHCP snooping provide network-level traffic filtering and prevent unauthorised IP assignments.
• Built for continuous enterprise operation with an estimated mean time between failures (MTBF) of 309,020 hours.
• Active thermal management using three internal fans to maintain operating temperatures during sustained heavy loads.
