2. Product Overview

Cisco Catalyst C9300X-24HXB-E is a 1U rackmount Layer3 stackable enterprise access switch running native Cisco IOS XE OS, targeted for campus wired access, smart building automation and high-density Wi-Fi access layer deployment. It adopts StackWise-1T high-speed stacking and StackPower+ cross-chassis power pooling architecture; the -B bulk variant is pre-configured with unified default settings in factory for mass project shipment and batch implementation.

Port & UPOE+ Power Specifications

24×Multi-Gigabit mGig copper downlink ports with auto speed ranging from 100Mbps to 10Gbps; every single port supports full 90W IEEE802.3bt UPOE+ power deliveryCisco
Default factory pre-installed single PWR-C1-1100WAC universal AC power supply; baseline available PoE budget = 735W. Optional hot-swappable redundant second 1100WAC PSU lifts total PoE budget up to 1590W; StackPower+ enables cross-stack power resource pooling among stacked switches to allocate full 90W UPOE+ for high-consumption endpoints
Single rear modular uplink expansion slot supporting official 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 coverage from 1Gbps up to 100GbpsCisco

Core Hardware Performance Parameters

Wire-rate standalone IPv4/IPv6 forwarding rate:654.76 Mpps; maximum aggregated forwarding throughput for full stack:1398.8 Mpps
Stacking capability: StackWise-1T with 1000Gbps per-stack backplane bandwidth; up to 8 identical C9300X-series switches can be stacked into one single logical switching device, supporting NSF/SSO sub-50ms non-stop forwarding failover protection
System core hardware: Quad-core x86 CPU, 16GB DRAM +16GB onboard flash memory, three variable-speed hot-swappable cooling fans; embedded onboard Catalyst 9800 wireless controller supports centralized management of maximum 200 Cisco enterprise wireless access points
Forwarding table scale:

MAC address table:96,000 entries; IPv4 routing table:96,000 entries; IPv6 routing table:48,000 entries; Multicast route table:24,000 entries; TCAM ACL/QoS resource:24,000 entries; Jumbo frame support up to 9198 Bytes; 48MB deep packet buffer for burst multicast and high-concurrency user traffic

3. Network Essentials (-E License) Feature Scope

Factory permanent Network Essentials license unlocks base Layer2 + limited basic Layer3 functions; advanced routing, TrustSec, MACsec, ETA need additional Network Advantage upgrade license

Layer 2 Full Core Functions

4094 VLAN support, RSTP/MSTP, LACP port-channel aggregation, port security, DHCP Snooping, DAI Dynamic ARP Inspection, 802.1X/MAB/CWA wired authentication, broadcast storm suppression, EEE Energy Efficient Ethernet, basic CoS/DSCP QoS mapping, embedded local WebUI management, mDNS gateway for BYOD service discovery

Basic Layer3 Functions under Essentials

Inter-VLAN SVI routing, static routing, RIP/RIPng, VRRP/HSRP, basic PIM sparse-mode multicast, fundamental standard ACL filtering; No native support for OSPF/EIGRP/BGP/IS-IS, MACsec, ETA, TrustSec SGT segmentation or Flexible NetFlow, above premium features require separate Network Advantage license upgradeCisco

Supported Management Interfaces

CLI console, HTTPS WebGUI, SNMPv3, NETCONF/YANG, RESTCONF programmable API, centralized syslog logging

Bulk (-B) Remark: Uniform factory preconfigured base startup-config for bulk shipment; all hardware and licensed functions fully consistent with standard C9300X-24HX-E non-bulk model
