Cisco Catalyst 9300-48P-A - Managed switch, Grey

The Cisco Catalyst 9300-48P-A 48-Port PoE+ Network Advantage switch is an L2/L3 rack-mountable unit designed for enterprise access layers. It features 48 Gigabit Ethernet (10/100/1000) RJ-45 ports, all supporting Power over Ethernet Plus (PoE+) to power connected devices directly. The system provides a switching capacity of 256 Gbit/s and a forwarding rate of 190.48 Mpps to maintain consistent packet delivery during peak traffic. By carrying both data and power over a single connection, this model removes the need for individual endpoint power supplies.

The chassis fits standard 19-inch racks and measures 445 mm wide by 44 mm high. Administrators can use integrated VLAN and Quality of Service (QoS) protocols to isolate traffic zones and prioritize latency-sensitive applications. Access Control List (ACL) functionality and DHCP snooping protect the network against unauthorised access and unapproved IP assignments. The architecture supports physical stacking, allowing multiple units to operate and be managed as a single logical switch. This simplifies administration when scaling local area network capacity.

• Supports up to 4,094 active VLANs for multi-tenant network segmentation.
• MAC address table capacity of 32,000 entries for large device deployments.
• Processes jumbo frames up to 9,198 bytes to reduce overhead during bulk data transfers.
• Built-in multicast routing distributes single data streams to multiple recipients without duplicating bandwidth.
• Integrated MIB support for hardware monitoring and configuration via standard SNMP tools.
