Cisco Catalyst C9500-16X-E 16-Port 10G SFP+ Core Switch (Network Essentials)

The Cisco C9500-16X-E is an enterprise-class, purpose-built 16-port 10G SFP+ fixed-core switch belonging to the secure and high-density Cisco Catalyst 9500 Series. Tailored as an ideal foundational block for corporate campus cores and high-speed aggregation layers, this high-performance switch operates under the dependable Network Essentials software license package.

With non-blocking line-rate performance and high-density 10G fiber connectivity, the C9500-16X-E is optimized for secure data transmission, heavy server virtualization, and fiber optic aggregation. Its architecture supports hot-swappable dual redundant power supplies and advanced Layer 3 routing features, delivering robust enterprise network reliability and fabric scaling.

When designing your enterprise backbone or finalizing a network hardware bill of materials (BOM), utilize the definitive specifications below for the Cisco C9500-16X-E:

Keep your enterprise core architecture running seamlessly with official compatible hot-swappable replacements:

• PWR-C4-650WAC-R: 650W AC Platinum-certified Power Supply Unit (AC Redundant Spare)

• PWR-C4-930WDC-R: 930W DC Power Supply Unit for DC-powered data center systems

• FAN-T1-R: Catalyst 9500 Type 1 Hot-swappable Fan Module (Rear-to-front or front-to-back airflow adaptive)

A: The essential difference lies in the software license package included with the switch hardware. The C9500-16X-E features the Network Essentials license, covering foundational Layer 2 capabilities and core Layer 3 routing features (such as OSPF, Static routing, and RIP). The C9500-16X-A includes the premium Network Advantage license, which unlocks advanced corporate routing protocols like Full BGP, EIGRP, EVPN-VXLAN virtualization, and Cisco TrustSec deep security segmentation.

A: Yes. All 16 fiber cages on the C9500-16X-E are completely dual-rate and backward compatible. The ports support standard 10G SFP+ optical transceivers, 1G SFP modules, Direct Attach Copper (DAC) twinax twin-core cables, and Active Optical Cables (AOC) depending on your structural requirements.

A: The Catalyst 9500 series does not use traditional hardware stacking cables (like StackWise-480/1T found in the Catalyst 9300 series). Instead, the C9500-16X-E utilizes Cisco StackWise Virtual technology. This allows two physical switches to be connected via standard 10G optical ports to form a single, synchronized logical virtual switch matrix, maximizing core network resilience.

A: Every Cisco C9500-16X-E core switch we distribute includes the official Cisco Enhanced Limited Lifetime Warranty (E-LLW). This legal contract guarantees Next-Business-Day (NBD) advance hardware replacement shipment (where logistically supported by regional hubs) and 90 days of 8x5 Cisco Technical Assistance Center (TAC) software validation support. For critical network grids, optional 24/7/365 Cisco Smart Net Total Care (SmartNet) contracts can be integrated.

A: It depends on the transceivers deployed in your network. If using 10G SFP+ SR modules, you should use multi-mode fiber (MMF) LC patch cords (OM3/OM4) for distances up to 300-400 meters. If your distribution links connect distant data closets, utilizing 10G SFP+ LR modules paired with single-mode fiber (SMF) LC cabling will extend your network footprint up to 10 kilometers.
