Full English Product Description: Cisco C9200L-48PXG-4X-E
1. Product Overview
Cisco C9200L-48PXG-4X-E is a 1U fixed-form-factor rack-mount enterprise access switch belonging to Catalyst 9200L portfolio, powered by UADP 2.0 Mini ASIC and Cisco IOS XE operating system, preloaded with perpetual Network Essentials (-E) License. Identical hardware configuration to C9200L-48PXG-4X-A, differentiated only by entry-level Essentials software instead of full Network Advantage feature set; optimized for mid/small enterprise branch, office floor, retail site, classroom deployments with high-density Wi-Fi6/6E AP, IP camera and PoE terminal access demands without advanced multi-service segmentation requirements.
2. Port Configuration
-
Total 48×IEEE802.3at PoE+ RJ45 downlink ports (max 30W per individual port):
12×Multi-Gigabit auto-negotiation mGig ports supporting 100M/1G/2.5G/5G/10GBase-T for high-speed next-gen Wi-Fi AP access;
36×10/100/1000BASE-T Gigabit copper ports for desktop PCs, IP phones and standard wired endpoints.
-
Fixed built-in uplink: 4×SFP+ slots, compatible with 1G/10G SFP+ optical transceivers for fiber uplink to aggregation/core switches.
-
Auxiliary management ports: 1×RJ45 Console, 1×USB-B console, 1×USB2.0 Type-A for local configuration backup and IOS firmware upgrade.
3. Core Hardware Specifications
-
Switching Capacity: 392 Gbps; Forwarding Rate: 291.66 Mpps
-
Memory: 2GB DRAM + 4GB onboard Flash for IOS XE image, configuration files and system log storage
-
Default built-in AC PSU: PWR-C5-1KWAC; base PoE power budget = 740W. Optional secondary redundant 1000W power supply can be installed to expand total PoE budget for full-load PoE+ operation across all ports.
-
Thermal design: Fixed integrated cooling fan array; redundant power optional for power resiliency in critical deployments.
-
Stacking: Supports Cisco StackWise-80 stacking technology with 80Gbps stacking bandwidth; maximum 8 identical switches can be stacked into a single logical switch for centralized management.
-
Physical dimension: 1.73in(H) ×17.5in(W) ×13.8in(D) (4.4cm ×44.5cm ×35.0cm), standard 19-inch 1U rack installation; CE, FCC, RoHS and TAA compliance certifiedCisco.
-
Operating environment: Ambient working temperature from -5℃ ~ +45℃, non-condensing relative humidity 5%~90%.
4. Network Essentials (-E) Licensed Software Features (Key difference vs -A Advantage License)
Perpetual IOS XE Network Essentials license with limited enterprise feature pool; SD-Access, VRF, VXLAN, full BGP/EIGRP and TrustSec are unavailable (reserved exclusively for Network Advantage -A edition)：
Layer 2 Full Supported Functions
IEEE802.1X port-based authentication, DHCP Snooping, DAI, basic ingress/egress port ACL, up to 4094 standard VLANs, STP/RSTP/MSTP, hierarchical QoS scheduling, Jumbo Frame up to 9198 bytes, basic SPAN port mirroring, AES-128 MACsec point-to-point link encryption.
Restricted Layer3 Routing Capability
Static routing, RIP, limited-scale OSPF (route entry quantity capped at 1000 entries); basic IPv4/IPv6 dual-stack forwarding; BGP, complete EIGRP, VRF, VXLAN, LISP and SD-Access fabric edge functionality are not supported under Essentials licensing tier.
Management & Basic Automation
CLI command line, HTTPS embedded web GUI, SNMPv3, baseline NETCONF/YANG model-driven configuration; compatible with Cisco DNA Center basic ZTP zero-touch provisioning without advanced SD-Access fabric orchestration capability.
5. Typical Application & Product Advantages
Deployment Scenarios
Small-to-medium branch office access, campus classroom network, chain retail store wired & wireless convergence, low/medium-density office floor PoE deployment, basic IP surveillance camera access layer without complex network isolation design.
Core Benefits
✅ 12-port native Multi-Gig copper directly connects 10G-grade Wi-Fi6/6E AP without external media converters;
✅ Four fixed SFP+ 10G uplinks reserve sufficient uplink bandwidth to bear bursty wireless uplink traffic;
✅ 740W native PoE budget cuts additional power injector investment for PoE-powered terminals;
✅ Cost-effective Essentials licensing matches flat, simple network architecture to lower initial procurement cost;
✅ StackWise-80 stacking enables seamless future capacity expansion and unified centralized O&M administration.
6. Warranty & Optional Service
Covered by Cisco Enhanced Limited Lifetime Warranty (ELLW); optional Smart Net Total Care (SNTC) service contract available for official Cisco TAC technical support, advance hardware replacement and authorized IOS software upgrade service.
