FAQs

Q: Does the C9500-48Y4C-A support Power over Ethernet?
A: No, this model does not support PoE. It is a data-only switch with 48x 25G SFP28 ports and 4x 40/100G QSFP28 uplinks. For PoE requirements, consider alternative Catalyst 9500 models with integrated PoE capabilities.

Q: What is included with the Network Advantage license?
A: The Network Advantage license provides advanced Layer 3 routing protocols (OSPF, EIGRP, BGP, MPLS), VRF-Lite, Software-Defined Access features, enhanced security capabilities including MACsec encryption, StackWise Virtual support, and full programmability via APIs. It enables comprehensive enterprise campus and core deployment scenarios.

Q: Can this switch be stacked with other Catalyst 9500 models?
A: Yes, the C9500-48Y4C-A supports Cisco StackWise Virtual technology, allowing you to connect two physical switches to operate as a single logical unit with up to 6.4 Tbps combined switching capacity. StackWise Virtual provides high availability, simplified management, and seamless redundancy across the stack.

Q: What transceivers are compatible with the SFP28 and QSFP28 ports?
A: The 48 SFP28 ports support 1G SFP, 10G SFP+, and 25G SFP28 optics for flexible deployment. The 4 QSFP28 uplink ports support 40G QSFP+ and 100G QSFP28 modules. Cisco recommends using genuine Cisco optics for full compatibility and support. Refer to the Cisco Transceiver Module Group (TMG) compatibility matrix for specific transceiver models.

Q: What makes this switch suitable for core and aggregation deployments?
A: The C9500-48Y4C-A delivers enterprise-grade performance with 3.2 Tbps switching capacity, advanced Layer 3 routing, high-density 25G connectivity, and 100G uplinks ideal for north-south traffic. It features dual redundant power supplies, NSF/SSO high availability, UADP 3.0 programmable ASIC, comprehensive security with MACsec, and support for advanced routing protocols required in core/aggregation roles.
