2. Product Overview
Cisco Catalyst C9300X-24HX-E is a 1U rack-mount enterprise stackable access switch built on UADP 2.0 ASIC and native Cisco IOS XE operating system, engineered for campus wired access, high-density Wi-Fi deployment, intelligent building IoT and high-power IP surveillance networking. Featuring StackWise-1T high-speed stacking and StackPower+ cross-chassis power pooling, it supports SD-Access readiness, zero-trust baseline security and essential Layer2/Layer3 routing functions under inherent Network Essentials licensing.
Port & UPOE+ Power Specifications
-
24×Multi-Gigabit mGig RJ45 downlink ports auto-negotiate 100Mbps/1G/2.5G/5G/10GBASE-T; every port supports IEEE802.3af(15.4W)/at(30W)/bt(Type4 90W) UPOE+ inline power supply
-
Factory default single pre-installed PWR-C1-1100WAC modular AC power supply; baseline available PoE+ budget = 735W. Optional redundant secondary 1100WAC hot-swappable PSU raises total PoE budget up to 1590W; StackPower+ enables cross-stack power resource sharing across stacked chassis to allocate full 90W UPOE+ to all required ports
-
Single rear modular uplink expansion slot compatible with dedicated C9300X uplink modules: C9300X-NM-8X (8×10G SFP+), C9300X-NM-4Y (4×25G SFP28), C9300X-NM-2Q (2×40G QSFP+), C9300X-NM-1C (1×100G QSFP28), flexible uplink bandwidth ranging from 1Gbps up to 100Gbps

-
TCAM ACL/QoS table capacity:24,000 entries; Jumbo frame support up to 9198 Bytes
-
Onboard packet buffer:48MB deep buffer for bursty multicast streaming and high-concurrency enterprise user traffic
3. Licensed Feature Scope under Network Essentials (-E Base License)
Factory pre-activated perpetual Network Essentials license unlocks below baseline features; advanced functions (full dynamic routing, MACsec, ETA, SD-Access EVPN/VXLAN) require separate upgrade to Network Advantage perpetual license or Cisco DNA subscription license:
Baseline Layer 2 Full Feature Set
4094 VLAN support, RSTP/MSTP spanning-tree, LACP port aggregation, port security, DHCP Snooping, DAI Dynamic ARP Inspection, 802.1X/MAB/CWA wired authentication, broadcast storm suppression, EEE Energy Efficient Ethernet, basic port QoS CoS/DSCP mapping
Limited Layer 3 Routing Functions
Static routing, RIP/RIPng routing protocol, VRRP, basic PIM-SM/SSM multicast routing, VLAN inter-VLAN routing only; no native OSPF/EIGRP/BGP/IS-IS support by default
Basic Security & Manageability
Baseline ACL filtering, SNMPv3, CLI/HTTP/RESTCONF/YANG programmable management, centralized syslog logging, basic Flexible NetFlow monitoring functions
Supplementary Note: Cisco DNA Advantage term license is separately required for DNA Center automation, network assurance, cloud telemetry and advanced analytics features, independent from Network Essentials hardware license.
