In the world of enterprise networking, Cisco’s Catalyst 9300 series is a go-to for SMBs and branch offices. Among its models, the C9300L-24UXG-4X-A and C9300L-48PF-4X-E are “regional specialists”—similar in core design but tailored to distinct port needs. Let’s break down their differences, from specs to real-world use.
These suffixes signal regional compliance:
C9300L-24UXG-4X-A: Certified for North America (FCC), optimized for high-density 10G access—ideal for U.S. branch offices.
C9300L-48PF-4X-E: Certified for Europe (CE), focused on PoE+ power delivery—built for offices and meeting rooms in EMEA regions.
Both share the same core switch chip, but port density directly impacts real-world performance:
Spec | C9300L-24UXG-4X-A | C9300L-48PF-4X-E |
---|---|---|
Forwarding Rate | 100Gbps (wire-speed) | 120Gbps (wire-speed) |
RAM | 4GB DDR4 (expandable to 8GB) | 4GB DDR4 (expandable to 8GB) |
Flash Storage | 128MB (firmware/config) | 128MB (firmware/config) |
Backplane Bandwidth | 480Gbps | 560Gbps |
In short: The 48-port model (-48PF-4X-E) handles more traffic, while the 24-port (-24UXG-4X-A) excels in smaller setups.
Ports: 24x10G SFP+ + 4x10G/25G Ethernet (expandable).
Strength: High 10G port density (24/28), perfect for bandwidth-heavy tasks (e.g., 4K video conferencing, data center edge).
Special Feature: Cisco DNA Center’s “Intelligent Traffic Scheduling” prioritizes critical apps like Zoom or file transfers.
Ports: 48x10G/1G auto-sensing (40+ support PoE+/PoE++) + 4x10G/25G expandable.
Strength: Over 80% PoE+ ports (40/48), with 90W per port (802.3bt compliant)—ideal for powering IP phones, APs, and cameras.
Special Feature: “Smart PoE Management” dynamically adjusts power usage, cutting energy costs by 20%.
Their looks reveal their intended use:
Size/Weight: -24UXG-4X-A is slimmer (43.2cm tall × 439.4mm wide), ~8.5kg; -48PF-4X-E is sturdier (47.6cm tall), ~11kg—choose based on rack space.
Port Layout: -24UXG-4X-A groups optical ports on top for easy fiber routing; -48PF-4X-E has symmetric PoE+ ports with deep cable managers to reduce clutter.
Power: -24UXG-4X-A uses a single power supply; -48PF-4X-E offers dual-power redundancy (critical for hospitals, banks).
Real-world feedback shows “fit” matters most:
SMBs/Small Branches: -24UXG-4X-A is simpler—fewer ports mean quicker configs via Cisco DNA Center’s app.
Large Branches/Enterprise Offices: -48PF-4X-E saves time—PoE+ ports eliminate separate power adapters, and “plug-and-play” APs/phones speed up deployment.
Shared Pain Point: Both have CLI-heavy interfaces (engineer-focused). New users should use the DNA Center app for quick settings.
Prices differ by ~30% (mostly due to port count and PoE+ modules). Hidden costs depend on your scenario:
≤30 Users: -24UXG-4X-A is cheaper—24 ports are enough, and 48 ports would be overkill.
50-100 Users: -48PF-4X-E saves money long-term—no extra power adapters or cabling for APs/cameras.
Multinationals: Buy region-specific models—mixing -A/-E leads to compliance and management headaches.
Core advantages? Precision engineering:
-24UXG-4X-A: The “budget-friendly high-speed pick” for tech startups or small branches needing 10G access.
-48PF-4X-E: The “all-in-one PoE+ solution” for offices/factories deploying masses of IP devices.
Both use Cisco IOS XE, but follow these steps to avoid issues:
Upgrade Steps (via Cisco DNA Center):
Log in, go to “Device Management” → “Software Upgrade,” and select region-specific firmware (-A/-E are not interchangeable!).
Check devices, click “Upgrade,” and let the system validate the firmware.
Restart after completion (schedule during off-peak hours).
Troubleshooting:
Issue 1: PoE+ ports fail post-upgrade (only -48PF-4X-E).
Cause: Non-CE-certified firmware causing PoE+ conflicts.
Fix: Revert to CE firmware, back up config (write memory
), and reload old firmware.
Issue 2: 10G ports unstable post-upgrade (only -24UXG-4X-A).
Cause: Non-FCC-compliant SFP+ modules.
Fix: Replace with Cisco SFP-10G-LR (FCC-certified) and check fiber loss (≤5dB).
Need: 30 employees, 20x4K video conferencing terminals (10G each), 10xAPs (10G uplink).
Solution: Deploy -24UXG-4X-A—24x10G ports connect APs/termsinals directly, 4x expansion ports link to core switch. Result: 0 video lag (down from 15%).
Need: 150-office + 20 meeting rooms, 80xIP phones (PoE), 50xAPs (PoE+), 10x8K cameras (PoE++).
Solution: Deploy -48PF-4X-E—40+ PoE+/PoE++ ports cover all devices, 800W total power (48×90W) avoids extra power lines. Result: £10k saved on cabling.
