FAQs

Q: What is the difference between the standard ports and multigigabit ports on this switch?
A: The C9300-48UXM-E has 36 ports that support 100M/1G/2.5G speeds, while 12 ports are true multigigabit capable of 100M/1G/2.5G/5G/10G speeds. All 48 ports support UPOE for high-power devices.

Q: What uplink modules are compatible with this switch?
A: The C9300-48UXM-E supports various network modules including C9300-NM-4G (4x1G), C9300-NM-8X (8x10G), C9300-NM-2Q (2x40G), C9300-NM-4M (4xmGig), and C9300-NM-2T (2x25G SFP28). The switch ships without a network module installed.

Q: How much PoE power can this switch deliver?
A: With the default 1100W power supply, the switch provides 490W PoE budget. UPOE supports up to 60W per port for demanding devices like Wi-Fi 6 access points, smart displays, and IoT sensors. Adding a secondary power supply can increase total PoE to 1590W.

Q: Can this switch be stacked with other Catalyst 9300 models?
A: Yes, the C9300-48UXM-E supports StackWise-480 technology and can be stacked with other C9300 and C9300X modular uplink models at 480 Gbps bandwidth. Up to 8 switches can form a single stack. It cannot stack with C9300L fixed-uplink models.

Q: What are the key capabilities of the Network Essentials license?
A: Network Essentials provides Layer 2 switching features, basic Layer 3 routing (static routing, RIP), security features like 802.1X authentication, QoS, ACLs, and network management via CLI, web GUI, and SNMP. Upgrade to Network Advantage is available for advanced Layer 3 routing and enterprise features.
