The Cisco Catalyst 9300 24-port UPOE switch is an enterprise-grade access layer device offering 24 RJ-45 UPOE ports, deep packet buffers, and the Network Advantage software suite.
The Catalyst 9300 24UB provides 24 universal Power over Ethernet (UPOE) ports, each capable of delivering up to 60 W per port.
UPOE extends IEEE 802.3at PoE+ by delivering up to 60 W per port over standard Cat5e/Cat6 cabling to power high-demand devices like PTZ cameras, video phones, and access points.
Deep buffer refers to the switch’s on-chip packet memory (4 MB per ASIC) that smooths traffic bursts and minimizes packet loss in high-volume environments.
Network Advantage adds advanced routing, Layer 3 features (OSPF, EIGRP, BGP), multicast, MACsec encryption, and flexible policy enforcement for secure, scalable networks.
It supports Cisco StackWise-480, enabling up to eight switches to operate as a single logical unit with 480 Gbps of stack throughput.
The switch delivers 176 Gbps switching capacity, 130 Mpps forwarding rate, and nonblocking wire-speed performance across all ports.
Typical power consumption is 200 W without PoE load; maximum system consumption can reach 1,600 W when all 24 UPOE ports deliver full power.
Ideal for enterprise access layer, high-density PoE deployments, IP telephony, wireless LAN access, and IoT device connectivity.
It supports Cisco optional uplink modules including 4× 10G SFP+, 8× 10G SFP+, and mixed 1/10G RJ-45/SFP solutions for flexible aggregation.
Yes, the switch offers full IPv6 routing, access control, QoS, and management capabilities as part of the Network Advantage license.
Management options include Cisco DNA Center, Cisco Prime Infrastructure, CLI via console/SSH, SNMP, REST APIs, and Web UI.
Cisco provides a limited lifetime hardware warranty, 90-day software updates, and optional Smart Net Total Care for 24×7 support and advanced replacement.
The unit measures 1.73″ H × 17.5″ W × 15.2″ D (2RU) and weighs approximately 16.8 lbs (7.6 kg).
Use the CLI command “power inline {port} priority {low|high}” or the Web UI PoE dashboard to allocate power budgets and priorities per port.
Yes, it features Energy-Efficient Ethernet (802.3az), fan-speed control, and intelligent PoE allocation to reduce power consumption.
The switch supports a total PoE budget of 1440 W when powered by two AC power supplies (PSU-1+PSU-2).
