C9300-24UXB-E Description
The C9300-24UXB-E is a Cisco Catalyst 9300 Series higher-scale stackable access switch for campus wiring closets that serve multigigabit endpoints and need deeper address and route tables. The switch has 24 multigigabit UPOE ports, a modular uplink slot, 640 Gbps of switching capacity, a 560W default PoE budget, a 64 MB packet buffer and Network Essentials licensing. As a higher-scale model it stacks only with other higher-scale Catalyst 9300 switches, not with standard C9300 units.

Product Performance
Key Features
All 24 copper ports negotiate 100M, 1G, 2.5G, 5G or 10G and deliver Cisco UPOE, so one port type serves Wi-Fi access points and high-draw endpoints.
The 24-port multigigabit higher-scale model carries a 64 MB buffer, which gives bursty multigigabit traffic more headroom than standard Catalyst 9300 multigigabit models.
The higher-scale group supports 64,000 MAC addresses, 112,000 IPv4 routes, 56,000 IPv6 routes and 18,000 QoS and ACL entries.
The -E suffix covers Layer 2 and OSPF routed access, while VRF, VXLAN, TrustSec, BGP and MACsec-256 need Network Advantage.
StackWise-480 supports up to eight members, but higher-scale models stack only with other higher-scale models and not with standard C9300 switches.
Uplink media comes from a separate Catalyst 9300 network module, with options from 1G SFP to 25G SFP28 and 40G QSFP, so the access ports do not fix the uplink speed.
Application Scenarios
In a wiring closet that serves many Wi-Fi access points and multigigabit desktops, the switch uses its 64,000 MAC address table and 112,000 route capacity to hold a large number of attached clients.
A floor of high-draw endpoints such as PTZ cameras and multigigabit access points can run from the 24 UPOE ports, with a second supply added when the 560W default budget runs short.
A building that already runs higher-scale Catalyst 9300 members can add this switch to the same stack, since higher-scale models stack only with each other.

C9300-24UXB-E is the Network Essentials version of the higher-scale 24-port Multigigabit UPOE switch also sold as C9300-24UXB-A, and the license tier is the only difference. A design that needs VRF, VXLAN, TrustSec, BGP or MACsec-256 on day one must order C9300-24UXB-A, since the upgrade term C9300-24-E-A-3, -5 or -7 applies only to an installed switch. The 64 MB buffer, 64,000 MAC addresses and 112,000 routes separate it from C9300-24UX-E, which has 32,000 MAC addresses and 32,000 routes, but higher-scale members stack only with other higher-scale models. Gigabit UPOE access with 830W of default PoE moves to C9300-24UB-E.
PoE Power Planning
|
Planning Item |
Cisco Confirmed Value |
Order Impact |
|---|---|---|
|
Default PoE budget |
C9300-24UXB-E is listed with 560W available PoE and PWR-C1-1100WAC-P as the default supply |
Check whether the powered endpoint count fits the base order before adding a secondary supply |
|
Secondary supply options |
The C9300-24UXB-E power table lists 910W with a 350W secondary supply, 1275W with a 715W secondary supply, and 1440W with an 1100W secondary supply |
Decide whether the second supply is for redundancy, more PoE budget, or both |
|
UPOE port class |
Cisco UPOE ports support Type 1, Type 2, Type 3, and Cisco UPOE powered devices up to 60W per port |
Avoid substituting a PoE+, UPOE+, or data-only model unless the endpoint power class changes |
|
StackPower design |
Catalyst 9300 modular-uplink switches support StackPower for shared stack power planning |
Add StackPower cabling only when the site design uses shared power across stack members |
Ordering Checklist
- Software subscription: Order a 24-port Essentials term: C9300-DNA-E-24-3Y, C9300-DNA-E-24-5Y or C9300-DNA-E-24-7Y. The configurator defaults to Cisco DNA Advantage with a 5-year term, which does not match a Network Essentials switch.
- Uplink module: Keep the default C9300-NM-8X, pick C9300-NM-4G, C9300-NM-4M, C9300-NM-2Q or C9300-NM-2Y, or select C9300-NM-NONE. The uplink slot takes Catalyst 9300 modules only; C9300X modules do not fit.
- Second power supply: A second PWR-C1-1100WAC-P is selected by default and C9300-SPS-NONE removes it. A single supply leaves the PoE budget at 560W.
- Stacking cables: The default 50 cm StackWise cable and 30 cm StackPower cable ship unless C9300-STACK-NONE and C9300-SPWR-NONE remove them. A stack with members in different rows needs longer cables, which the 50 cm default does not cover.
- Power cords: Select the cord type for the destination country; two cords ship with the switch. The configurator defaults to North America cords.
