C9300-24U-A Description
The C9300-24U-A is a Cisco Catalyst 9300 Series stackable access switch for wiring closets that power endpoints drawing up to 60W over 24 Gigabit copper ports. The switch has 24 10/100/1000 Cisco UPOE ports, an 830W PoE budget on the default 1100W supply, a modular uplink slot and 208 Gbps of switching capacity. The -A suffix carries Network Advantage, which adds BGP, VXLAN, MPLS and MACsec-256 to the Layer 2 and routed-access functions of Network Essentials.

Product Performance
Key Features
Each port can deliver up to 60W, and the default 1100W supply leaves 830W for PoE, about 34W per port if all 24 draw power at once. A second 1100W supply lifts the budget to 1440W, which covers a full 60W on every port.
Uplinks come from a Catalyst 9300 network module such as the 8 x 10G/1G SFP+ C9300-NM-8X or the 2 x 40G C9300-NM-2Q, and the default configuration ships without one. Changing uplink speed later means swapping the module rather than the switch.
Up to eight switches join one stack over 480 Gbps StackWise cables, and members must carry the same license level. StackPower links up to four switches in a ring so their supplies share one power pool.
Network Advantage adds BGP, IS-IS, VRF, VXLAN, LISP, MPLS, NETCONF and RESTCONF on top of Network Essentials. It also supports MACsec-256, where Network Essentials stops at MACsec-128.
The default 1100W supply sets the 830W budget, and a second supply is optional rather than required for UPOE. Adding one raises the budget and gives power redundancy.
Two supply slots allow redundancy, though the switch ships with a single supply in slot 1. Three field-replaceable fans provide N+1 cooling.
Application Scenarios
A floor closet running UPOE-class endpoints such as video phones and displays can power them directly from the 24 copper ports and carry their traffic to the distribution layer through the uplink module.
A campus building can stack several of these switches into one StackWise-480 unit, with Network Advantage providing the BGP, VXLAN and MPLS functions that a segmented access layer calls for.
Where closets differ in how far they sit from the core, the same 24-port switch takes a 1G, 10G, 25G or 40G network module to match each fiber run.

C9300-24U-A and C9300-24U-E share the same 24-port UPOE hardware, 830W default PoE budget and StackWise-480 support, and differ only in Network Advantage versus Network Essentials, so a site that can run on Essentials can order C9300-24U-E and give up the Advantage tier. Cisco lists no downgrade PID, only the Essentials-to-Advantage upgrade through C9300-LIC=. Where every powered device is PoE+ class, C9300-24P-A fits, with a 715W default supply and 445W of PoE against 830W. Above 24 ports, C9300-48U-A offers 48 UPOE ports on an 822W default budget and 256 Gbps standalone switching against 208 Gbps.
PoE Power Planning

Cisco Confirmed Value |
Order Impact |
|---|---|---|
|
Default PoE budget |
C9300-24U-A is listed with 830W available PoE and a PWR-C1-1100WAC-P default supply |
Match the endpoint count and power draw to the 830W switch-level budget |
|
Power supply slots |
Catalyst 9300 switches use two internal power supply module slots |
Decide whether the second slot needs a redundant supply or a blank module |
|
UPOE versus PoE+ |
C9300-24U-A is the Cisco UPOE model, while C9300-24P-A is the PoE+ model |
Prevent a lower-power PoE+ order line from replacing a UPOE requirement |
|
StackPower |
C9300-24U-A supports StackPower |
Add StackPower cables only when the stack power design requires shared power |
Ordering Checklist
- Subscription: Select C9300-DNA-A-24-3Y, -5Y or -7Y, the 24-port Cisco DNA Advantage term. New orders need a subscription of the same tier as the network license, and the configurator defaults to Advantage with a 5-year term.
- Uplink module: Keep the default C9300-NM-8X, choose another C9300-NM module, or select C9300-NM-NONE. The uplink slot ships with C9300-NM-8X unless changed.
- Second power supply: A second PWR-C1-1100WAC-P is added by default; C9300-SPS-NONE removes it. Without it the PoE budget stays at 830W instead of up to 1440W.
- Stack and StackPower cables: A 50 cm StackWise cable and a 30 cm StackPower cable are added by default; C9300-STACK-NONE and C9300-SPWR-NONE remove them. A stack needs a StackWise cable of the right length, so a stand-alone switch can drop both.
- Power cords: Select the cord type for the destination country. Two cords ship, and the configurator defaults to North American cords.
