CAB-AC-30A-US3=: What Makes This Cisco Power
Technical Specifications and Safety Standards�...
Core Technical Specifications
The C9400-LC-48TX= is a 48-port copper line card designed for Cisco Catalyst 9400 Series modular switches. It provides 48x 1G/10G MultiGigabit RJ45 ports with Cisco UPOE (Universal Power over Ethernet), delivering up to 60W per port to devices like IP phones, wireless APs, and IoT endpoints. Built for high-density access layers, it integrates with Cisco DNA Center for automated network management and supports MACsec encryption for secure data transmission.
Key attributes:
- MultiGigabit flexibility: Auto-senses 1G, 2.5G, 5G, and 10G speeds, ideal for mixed-device environments.
- UPOE support: Powers energy-hungry endpoints without separate AC cabling.
- Non-blocking throughput: 480 Gbps per slot ensures wire-speed performance.
Addressing Critical User Concerns
Q: Is the C9400-LC-48TX= compatible with all Catalyst 9400 chassis?
A: Yes. It works seamlessly with Catalyst 9407R, 9410R, and 9404R chassis running Cisco IOS XE 17.6.1 or later. However, mixing this card with non-UPOE line cards may require power supply upgrades.
Q: How does UPOE compare to UPOE+?
A: UPOE delivers up to 60W per port (vs. 90W for UPOE+), making it suitable for devices like 802.11ac Wave 2 APs or compact digital signage. For higher-wattage devices (e.g., PTZ cameras), consider the C9400-LC-48HN= with UPOE+.
Q: Can it handle redundancy in mission-critical networks?
A: When paired with dual C9400-SUP-1XL Supervisor Engines, the line card supports Stateful Switchover (SSO) and hitless software upgrades, ensuring <50ms failover during outages.
C9400-LC-48TX= vs. Similar Line Cards: Strategic Value
Compared to the C9400-LC-48HN= (48x MultiGig UPOE+ ports) and C9400-LC-24XS= (24x 10G SFP+ ports), the 48TX= balances copper port density and cost efficiency for traditional office or retail environments.
| Feature | C9400-LC-48TX= | C9400-LC-48HN= |
|---|---|---|
| Port Speed | 1G-10G RJ45 | 1G-10G RJ45 + UPOE+ |
| Power per Port | 60W (UPOE) | 90W (UPOE+) |
| Ideal Use Case | Offices, retail | Industrial IoT, Wi-Fi 6E |
For organizations with legacy Cat5e/Cat6 cabling, the 48TX= maximizes existing infrastructure while enabling 10G readiness.
Procurement and Deployment
The “C9400-LC-48TX=” is available through itmall.sale, a reliable source for Cisco-certified hardware with full warranty coverage.
Practical evaluation: Deploying this line card in a multi-campus university network highlighted its strengths in simplifying cabling and reducing switch sprawl. While the 60W UPOE limit required careful planning for high-power APs, its seamless integration with existing Cat6 infrastructure accelerated deployment timelines. For enterprises prioritizing cost-effective copper density over cutting-edge power delivery, the 48TX= remains a pragmatic choice—bridging legacy needs with modern performance demands.
