FAQs

Q: What makes the C9300-48UB-A a higher-scale model?
A: The C9300-48UB-A features a deeper 32MB packet buffer compared to standard models, optimized for handling bursty multimedia traffic, large routing tables, and storage-intensive environments. It must be stacked only with other higher-scale models (C9300-24UB, C9300-24UXB, C9300-48UB).

Q: What uplink modules are compatible with this switch?
A: The C9300-48UB-A supports C9300-NM-4G (4x 1G SFP), C9300-NM-8X (8x 10G SFP+), C9300-NM-2Q (2x 40G QSFP+), C9300-NM-4M (4x mGig), and C9300-NM-2Y (2x 25G). It also supports legacy Catalyst 3850 network modules including C3850-NM-4-1G, C3850-NM-4-10G, C3850-NM-2-40G, and C3850-NM-8-10G.

Q: Can this switch be stacked with standard Catalyst 9300 models?
A: No, the C9300-48UB-A higher-scale models cannot be stacked with standard Catalyst 9300 or 9300X models. They must be stacked only with other higher-scale SKUs (C9300-24UB, C9300-24UXB, C9300-48UB) using StackWise-480 technology.

Q: What is the maximum PoE budget available?
A: The default configuration provides 822W PoE budget with the included 1100W power supply. By adding optional secondary power supplies, the PoE budget can be increased to 1172W (with 350W PSU), 1537W (with 715W PSU), or 1800W (with 1100W PSU).

Q: Does the Network Advantage license include Layer 3 routing?
A: Yes, the Network Advantage license includes full Layer 3 routing capabilities with support for OSPF, EIGRP, BGP, IS-IS, policy-based routing, and advanced features like MACsec-256 encryption, Flexible NetFlow, VXLAN, MPLS, and comprehensive QoS.
