Stacking and Naming Convention

Stacking Technology: The Cisco Catalyst 9300 Series supports StackWise-480 technology, allowing up to 8 switches to be stacked, providing a total stacking bandwidth of 480 Gbps.
Naming Convention: Each model follows a specific naming structure: C9300: Indicates the product series (Cisco 9300). 24/48: Refers to the number of ports. T/P/U/S: Denotes the PoE type (T: No PoE, P: PoE+, U: UPOE, S: SFP). 4G/4X: Refers to the type of uplink ports (G: 1GbE, X: 10GbE). U: Indicates higher bandwidth models (e.g., 10GbE or 40GbE).
C9300: Indicates the product series (Cisco 9300).
24/48: Refers to the number of ports.
T/P/U/S: Denotes the PoE type (T: No PoE, P: PoE+, U: UPOE, S: SFP).
4G/4X: Refers to the type of uplink ports (G: 1GbE, X: 10GbE).
U: Indicates higher bandwidth models (e.g., 10GbE or 40GbE).

FAQ for Cisco 9300 Series Switches

Q1: How are uplinks selected for a C9300-24T?

C9300-24T uses a modular network-uplink slot. Select a supported C9300 network module from Cisco's data sheet and ordering guide according to required speed, optics, software, and redundancy; do not treat a shorthand name as a complete switch PID.

Q2: How do I choose the appropriate PoE type for my switch?

Choose a PoE-capable PID from the endpoint's negotiated standard, peak power, cable length and quality, total switch power budget, PSU configuration, redundancy target, and environmental limits. Not every C9300 model supplies PoE.

Q3: How many Cisco 9300 switches can be stacked together?

StackWise capacity, bandwidth, member count, cables, and mixed-member rules vary across C9300, C9300L, C9300X, and software releases. Validate every member PID and release against Cisco's current stacking documentation before ordering.

Q4: Does the Cisco 9300 Series support 10GbE and 40GbE uplinks?

Uplink speed depends on the exact base switch and supported network module or fixed-uplink PID. Use Cisco's data sheet and ordering guide to map required 10G, 25G, 40G, or other connectivity; do not infer uplinks from access-port model names.

Q5: What is the warranty for the Cisco 9300 Series?

Warranty, replacement service, software access, and support are governed by the exact PID, region, purchase channel, purchase date, and Cisco terms. Confirm them in writing; this article does not promise next-business-day replacement.

Conclusion

The Cisco 9300 Series offers a range of options suitable for both small and large networks, with advanced features like stackability, PoE+, and Layer 3 routing capabilities. These switches provide the reliability, security, and performance required for modern enterprise infrastructures. Whether you are upgrading or building a new network, the Cisco 9300 Series is a top choice for high-performance, secure network environments.
