FAQs

Q: What uplink modules are compatible with the C9300-48P-A?
A: The switch supports modular uplinks via network modules including C9300-NM-4G (4x 1G SFP), C9300-NM-8X (8x 10G SFP+), C9300-NM-2Q (2x 40G QSFP+), and C9300-NM-2Y (2x 25G SFP28). Modules are sold separately.

Q: Can I increase the PoE budget beyond 740W?
A: Yes, the switch supports dual redundant power supplies. By adding a secondary PSU (350W, 715W, or 1100W), you can increase the total PoE budget up to 1440W depending on the PSU combination.

Q: Is the C9300-48P-A stackable with other Catalyst switches?
A: Yes, it supports StackWise-480 stacking with other C9300 and C9300X modular uplink models (up to 8 switches). It cannot stack with C9300L fixed uplink models or older Catalyst 3850/3650 switches.

Q: What is included with the Network Advantage license?
A: Network Advantage is a perpetual license providing advanced Layer 3 routing (32,000 IPv4 / 16,000 IPv6 entries), MACsec encryption, MPLS, advanced QoS, and full Cisco DNA Center integration. Additional DNA features may require subscription.

Q: Does this switch support Perpetual PoE and Fast PoE?
A: Yes, Perpetual PoE maintains power to connected devices during switch reload, and Fast PoE delivers power before the OS fully loads, minimizing downtime for critical IoT endpoints.
