Product Overview & Enterprise Deployment Value
The Cisco Catalyst C9300L-48P-4X-E is a premier enterprise-class stackable access switch designed to power modern IoT, smart building, and high-density wireless environments. Running on the unified Cisco IOS-XE open operating system, this powerhouse offers 48 Gigabit Ethernet ports with Full PoE+ (Power over Ethernet) support, accompanied by 4 fixed 10G SFP+ uplinks for high-bandwidth core connectivity.
Engineered for organizations transitioning to Wi-Fi 6/6E architectures and dense IP surveillance networks, the C9300L-48P-4X-E delivers up to 505W of default PoE budget (expandable to 1440W with dual power supplies). Driven by StackWise-320 technology, it enables administrators to stack multiple units to achieve a resilient, single-logical-switch fabric with 320 Gbps of stacking bandwidth.

Technical FAQ & Product Comparisons (Google SEO Optimized)
Our Cisco-certified networking experts have compiled the following FAQ to address technical specifications, hardware compatibility, and deployment strategies.
Q1: What is the primary difference between Cisco C9300L-48P-4X-E and C9300L-48T-4X-E?
A: The fundamental difference is Power over Ethernet (PoE) support. The C9300L-48P-4X-E features 48 ports that support PoE+ (IEEE 802.3at) to supply power directly to downstream devices such as IP cameras, VoIP phones, and Access Points. The C9300L-48T-4X-E is a "Data-Only" switch with no power delivery capabilities. If your infrastructure includes endpoint hardware requiring network power, the 48P model is essential.
Q2: How does the C9300L-48P-4X-E compare to the modular C9300-48P-E switch?
A: The differences lie in uplink flexibility and stacking bandwidth.
Uplinks: The C9300L features fixed uplinks (4x10G SFP+) integrated into the chassis, which cannot be swapped out. The standard C9300 has a modular slot supporting hot-swappable uplink modules (up to 40G/100G).
Stacking: The C9300L utilizes StackWise-320 (320 Gbps bandwidth), whereas the standard C9300 utilizes StackWise-480 (480 Gbps bandwidth).
For businesses with stable 10G uplink needs, the C9300L offers a more cost-effective enterprise alternative.
Q3: How can I increase the PoE power budget of this switch to support more PoE+ devices?
A: Out of the box with a single 715W AC power supply, the switch provides a 505W PoE budget. To maximize your PoE deployment to 1440W, you can configure the switch with a second redundant power supply, utilizing two PWR-C1-1100WAC-P power modules. This allows all 48 ports to concurrently deliver full 30W PoE+ power.
Q4: Are the 4x10G fixed uplink ports backwards compatible with 1G SFP optical modules?
A: Yes, absolutely. The fixed 10G SFP+ uplink slots are dual-rate. They seamlessly support both 10G SFP+ modules (such as 10GBASE-SR, 10GBASE-LR) and standard 1G SFP modules (such as 1000BASE-SX, 1000BASE-LX). This allows you to deploy the switch in your existing 1G core network and upgrade to a 10G core later without changing the switch hardware.
