​​Overview of the C9400-LC-48H-UL=​​

The ​​Cisco Catalyst C9400-LC-48H-UL=​​ is a 48-port line card designed for the Catalyst 9400 Series modular chassis. Built for ​​high-density campus core or distribution layers​​, it combines ​​multi-gigabit connectivity​​ with ​​Power over Ethernet (PoE++)​​ to support demanding environments like large campuses, hospitals, or IoT-driven smart buildings.

​​Key Technical Specifications​​

• ​​Port Configuration​​: 48x ​​1/2.5/5/10G Multi-Gigabit Ethernet ports​​ (RJ45) + 4x ​​40G QSFP+ uplinks​​.
• ​​PoE Capabilities​​: ​​UPOE+ (90W per port)​​ for high-power devices like PTZ cameras, Wi-Fi 6/6E APs, and digital signage.
• ​​Performance​​: ​​1.44 Tbps system throughput​​ per slot when paired with a C9400 Supervisor Engine.
• ​​Security​​: ​​Cisco Trustworthy Systems​​ with hardware-rooted trust, secure boot, and integration with ​​Cisco DNA Center​​ for zero-trust segmentation.

​​Addressing Critical User Concerns​​

​​Q: Can this line card handle both legacy and modern devices?​​
Yes. The ​​auto-sensing Multi-Gig ports​​ negotiate speeds from 1G to 10G, ensuring backward compatibility with older devices while supporting newer 10G endpoints.

​​Q: What PoE++ use cases does it support?​​
With ​​90W per port​​, it powers high-demand IoT devices like building automation systems, 802.11ax APs, and industrial sensors without external power sources.

​​Q: How does it scale for large deployments?​​
The 40G uplinks aggregate traffic to the chassis backplane, while ​​Cisco StackWise Virtual​​ allows stacking multiple Catalyst 9400 chassis as a single logical switch.

​​Q: Is it compatible with existing Catalyst 9400 chassis?​​
Yes, but verify supervisor engine compatibility (e.g., C9400-SUP-1XL or newer).

​​Licensing and Procurement via itmall.sale​​

For enterprises needing reliable sourcing, the C9400-LC-48H-UL= is available through itmall.sale, offering:

• ​​Chassis bundle discounts​​ (line card + supervisor + power supplies).
• ​​PoE capacity planning tools​​ to avoid oversubscribing power budgets.
• ​​5-year extended hardware warranties​​ for mission-critical networks.

​​Why This Line Card Is a Game-Changer​​

In deploying Catalyst 9400 systems for university campuses, the C9400-LC-48H-UL= stands out for ​​consolidating power and data delivery in space-constrained IDF closets​​. While its upfront cost is significant, the elimination of external PoE injectors and support for mixed-speed devices reduces long-term operational complexity. For organizations scaling smart building initiatives, this line card future-proofs investments by bridging legacy infrastructure and next-gen IoT demands.
