Cisco Catalyst 9300L-48P-4G-A - Managed Switch, Grey

The Cisco Catalyst 9300L-48P-4G-A is a 48-port managed PoE+ switch with four 1G SFP uplinks, designed for enterprise branch and campus networks. The unit features 48 RJ-45 Gigabit Ethernet ports and four dedicated 1G SFP slots for fibre uplinks. It offers a 176 Gbit/s switching capacity and a 130.95 Mpps forwarding rate to handle heavy workloads. The high port density allows for the simultaneous connection of workstations, IP phones, and access points.

The 1U chassis fits into standard 19-inch network racks. The switch provides a 550 W total PoE budget, delivering up to 30 W per port to connected devices. Administrators can segment and secure traffic using up to 4,000 active VLANs and standard Access Control Lists (ACLs). Quality of Service (QoS) protocols prioritise critical data, and DHCP snooping monitors IP assignments. The stackable architecture allows multiple units to operate as a single logical entity.
