How to budget a Cisco Catalyst 9300 refresh: ports, PoE, licensing, and services
A Catalyst 9300 quote is more than switch SKUs. Here is the full picture — port headroom, PoE budget, licensing tiers, optics, cabling, and the install labor that often gets missed.
The hardware line items on a switching quote are the easy part. The numbers that move a budget — and the ones that get missed — are power, licensing term, optics, cabling, and the labor to cut everything over without downtime. Here is how to think about each before you sign.
1. Ports and stacking
Size port count with roughly 10% headroom for growth, then decide on stacking. The Catalyst 9300 supports up to eight switches in a StackWise stack that behaves as one logical unit with hitless failover, and you can mix PoE, UPOE, data, and multigigabit models in the same stack.
2. PoE budget is a real constraint
Endpoints decide your power budget. The 9300 supports PoE, PoE+, Cisco UPOE (60W), and UPOE+ (90W per port); a fully loaded switch with dual power supplies delivers up to roughly 1440W of PoE. High-power devices — pan-tilt-zoom cameras, Wi-Fi 7 APs, building IoT — can exhaust a budget faster than the port count suggests.
3. Licensing: tier and term
A perpetual Network license ships with the hardware. The subscription decision is the tier — Network/DNA Essentials, Advantage, or Premier — and the term, typically 1, 3, 5, or 7 years. Advantage and above add automation and assurance. Aligning and co-terming the subscription with support avoids a renewal scramble later.
4. The line items people forget
- Uplink modules and transceivers — the optics that connect access to distribution.
- Structured cabling — copper to the desk, fiber to the closet, and patch.
- Smartnet 24×7×4 on the right term.
- Install labor — rack-and-stack, configuration, labeling, and a phased cutover.
“A switch refresh that ignores power, optics, and install labor is not a budget — it is a deposit.”

Put it together
Scope hardware, power, licensing, optics, cabling, and services as one estimate so there are no surprises at cutover. That is exactly what the Uniqcli quote builder does — then we validate the final Cisco bill of materials before signature.
