C9300-24H-A Description
The C9300-24H-A is a Cisco Catalyst 9300 Series stackable access switch built around 24 Cisco UPOE+ copper ports and a modular uplink bay, positioned for wiring closets that must power high-draw endpoints such as pan-tilt-zoom cameras, Wi-Fi 6E access points, and lighting controllers rather than just phones and standard APs. The default PWR-C1-1100WAC-P supply delivers an 830W PoE budget out of the box, and Cisco documents a design ceiling of 2160W once a second supply is added, giving the switch headroom that a standard PoE+ model in the same family cannot reach. It carries the Network Advantage perpetual license, which unlocks unrestricted routed scale, VRF/VXLAN/LISP segmentation, and MACsec-256 on top of the same hardware sold as C9300-24H-E with Network Essentials. StackWise-480 support at up to 8 members and Cisco StackPower let a closet grow in port count and shared power resilience without changing the switching platform.

Key Features
The default 1100W supply already clears an 830W PoE budget, and Cisco’s documented 2160W ceiling with a second supply means the same chassis can carry pan-tilt-zoom cameras, lighting controllers, or Wi-Fi 6E radios that a 60W PoE+ port budget would starve.
Because the uplink bay ships empty, the closet design can defer whether to run 10G SFP+ (C9300-NM-8X), 40G QSFP+ (C9300-NM-2Q), or 25G SFP28 (C9300-NM-2Y) until the distribution-layer speed is confirmed, instead of locking in a fixed uplink at time of switch order.
Network Advantage adds VRF, VXLAN, LISP, and Cisco TrustSec segmentation plus NETCONF/RESTCONF/YANG automation and MACsec-256 on top of the same hardware sold as C9300-24H-E, so a design that needs network segmentation or model-driven automation at this closet does not need a separate switch model.
StackPower lets up to 4 stack members pool power across a ring, so a member running near its PoE ceiling can draw spare capacity from a neighbor instead of forcing every unit in the stack to carry its own second supply.
StackWise-480 stacks up to 8 units at full speed only with other C9300 modular-uplink switches at the same Network license tier, so the closet’s growth path stays inside the standard C9300 line rather than mixing in C9300X or C9300L hardware.
C9300-24H-A requires Cisco IOS XE Release 16.5.1a or later, so a site standardizing a single software image across an existing Catalyst 9300 fleet, or across a shared StackWise-480 stack, has to confirm that floor before adding this switch rather than assuming an older image already in production will support it.
Application Scenarios
Deployed in wiring closets that feed PTZ security cameras, digital signage, and IoT lighting controllers where individual ports need more than a standard PoE+ 30W allocation and the 830W default budget covers a full closet without a second supply.
Used as an access-layer switch in campus designs that rely on VRF or VXLAN segmentation and Cisco TrustSec policy enforcement at the edge, where the Network Advantage license already on this hardware avoids a separate license order.
Placed in a StackWise-480 stack alongside other C9300 Network Advantage members where StackPower pools power headroom across the ring, supporting closets that plan to add high-draw endpoints over time without pre-provisioning a second supply on every unit.

- Ordering C9300-24H-A instead of the base C9300-24H-E adds Network Advantage segmentation, unrestricted routed scale, and MACsec-256 on identical hardware; the ordering guide documents no in-place upgrade PID from Essentials to Advantage on standard C9300 modular-uplink hardware, so a design that starts on C9300-24H-E and later needs Advantage features has to re-order as C9300-24H-A rather than field-upgrade the license.
- Moving up to C9300-48H-A doubles port count to 48 and raises the maximum PoE budget with a secondary supply to 2880W against 2160W on C9300-24H-A, which only matters when the closet’s endpoint count is already approaching 24 high-draw UPOE+ devices; a design that fits inside 24 ports gains nothing from the larger chassis.
- C9300-24UX-A trades UPOE+ for Multigigabit uplink-class ports and a lower 560W default PoE budget, which fits Wi-Fi 6/6E access points and Multigigabit endpoints better than the fixed 1G UPOE+ ports on C9300-24H-A, but it cannot reach the 2160W UPOE+ ceiling because it is a UPOE (not UPOE+) platform.
- For deciding which SKU to order in this group, settle the PoE-per-port class first (UPOE+ high-draw versus Multigigabit UPOE), then size port count against endpoint headroom; Network license tier and StackWise-480 stacking do not separate C9300-24H-A from C9300-48H-A since both already carry Network Advantage on the same stacking generation.
Selection Guide
1. When The 830W Default Budget Already Covers The Closet
C9300-24H-A ships with an 830W PoE budget on its single default 1100W supply; a closet that mixes cameras, phones, and Wi-Fi 6 APs within that envelope does not need to budget for a second power supply at order time, keeping the bill of materials on the single-supply configuration.
2. Second Supply Buys PoE Headroom, Not Just Redundancy
Cisco’s documented ceiling only reaches 2160W once any second supply is installed, and upgrading the primary supply to PWR-C1-1900WAC-P alone does not raise the budget past the same design limit; a plan to grow past 830W of connected PoE load needs a second supply in the order, not just a bigger single supply.
3. License Tier Locks In At Order Time
Because no in-place upgrade PID moves standard C9300 modular-uplink hardware from Network Essentials to Network Advantage, C9300-24H-A only earns its higher tier over the lower-tier C9300-24H-E when Advantage-tier segmentation or automation is a known requirement, since the tier cannot be changed on the same chassis later.
4. Uplink Module Choice Stays Open Until Distribution Speed Is Set
The modular uplink bay ships empty on C9300-24H-A, so the decision between a 10G SFP+ module (C9300-NM-8X), a 40G QSFP+ module (C9300-NM-2Q), or a 25G SFP28 module (C9300-NM-2Y) can wait until the distribution-layer uplink speed is confirmed, rather than being fixed at switch order.
5. Port Count Ceiling Before Moving To The 48-Port Sibling
C9300-24H-A tops out at 24 UPOE+ ports per unit; a closet that is already sizing past 24 high-draw endpoints per wiring closet should size the 48-port C9300-48H-A instead of planning to stack two 24-port units purely for port count.
PoE Power Planning
|
Planning Item |
Value or Check |
|---|---|
|
Default PoE budget |
830W with the single default PWR-C1-1100WAC-P supply, no secondary supply installed. |
|
Maximum PoE budget |
2160W design ceiling once any supported secondary supply is installed; upgrading the primary supply alone to PWR-C1-1900WAC-P does not raise the ceiling further. |
|
UPOE+ port coverage |
Cisco documents Cisco UPOE+ (90W per port) as available on 21 of the 24 ports when the switch is configured per datasheet Table 12. |
|
Secondary supply requirement for full UPOE+ |
Datasheet Table 12 specifies 1 PWR-C1-1100WAC/1100WAC-P plus 1 PWR-C1-715WAC/715WAC-P/715WDC as the qualifying pair for UPOE+ on 21 ports. |
|
StackPower option |
StackPower can share power across up to 4 stacked members (8 with XPS-2200), reducing the need to size every unit’s PoE budget independently. |
Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Second power supply need |
Confirm whether the connected PoE load will exceed 830W, and if so include a second supported power supply in the same order. |
The switch does not reach its 2160W ceiling on a single supply regardless of supply wattage. |
|
Network license and subscription match |
Confirm the Cisco Catalyst or Cisco DNA subscription ordered alongside C9300-24H-A is the Advantage tier, matching the built-in Network Advantage license. |
A mismatched subscription tier can stall activation or leave Advantage features unlicensed. |
|
Smart Account binding |
Confirm the target Smart Account and Virtual Account before ordering. |
Catalyst 9300 is a smart-licensed SKU; entitlements tied to the wrong account can delay activation. |
|
Uplink module selection |
Confirm which network module (C9300-NM-8X, C9300-NM-2Q, C9300-NM-2Y, C9300-NM-4M, or C9300-NM-4G) matches the distribution-layer uplink speed before the module ships as a separate line item. |
The uplink bay ships empty; the wrong module choice mismatches the intended uplink speed. |
|
Blank module for single-supply configuration |
Confirm a blank power supply module is ordered for the second bay when only one supply is installed. |
Cisco documents this as a caution for maintaining airflow and fan noise levels. |
