C9300-24UXB-E Description
C9300-24UXB-E is a Cisco Catalyst 9300 higher-scale stackable access switch with 24 multigigabit Cisco UPOE copper ports, modular uplinks, Network Essentials, a 560W default PoE budget, and the 24UXB deep-buffer hardware profile.
The `-E` suffix places this 24UXB hardware in Network Essentials, while C9300-24UXB-A keeps the same higher-scale mGig UPOE platform under Network Advantage. Compared with C9300-24UX-E, the buyer-facing change is the higher-scale 24UXB profile, including the 64 MB packet buffer and the higher-scale Catalyst 9300 stack boundary.
Quote review should confirm the C9300 network module, Catalyst Essentials 24-port term license, higher-scale stack membership, default PWR-C1-1100WAC-P supply, StackWise-480 cable length, StackPower cable plan, regional power cord, and copper cabling target for 5G or 10G access links.

Key Features
C9300-24UXB-E combines the higher-scale 24UXB hardware profile with Network Essentials, making it the Essentials counterpart to C9300-24UXB-A.
The downlink block is 24 multigigabit copper ports that support 100M, 1G, 2.5G, 5G, and 10G operation with Cisco UPOE.
The 24UXB profile carries a 64 MB packet buffer and higher route, MAC, QoS, ACL, and Flexible NetFlow scale values than standard Catalyst 9300 modular-uplink models.
The base switch does not fix the uplink media, because Cisco lists separate C9300 network modules for 1G SFP, 10G SFP+, 25G SFP28, 40G QSFP, and 10G/mGig copper uplinks.
C9300-24UXB belongs to the higher-scale Catalyst 9300 group, and Cisco states that the higher-scale SKUs need to stack with other higher-scale models.
The default 560W PoE budget must be checked against endpoint demand, with secondary power supply choices used when the powered-device plan needs more budget or redundancy.
Application Scenarios
C9300-24UXB-E fits access closets moving from 1G copper toward 2.5G, 5G, or 10G copper links while staying on the Network Essentials license tier.
Add this SKU when the existing Catalyst 9300 stack is based on higher-scale members and the new switch must match the 24UXB multigigabit UPOE profile.
The switch is appropriate where the downlink requirement is fixed at 24 mGig UPOE ports but the uplink choice still depends on a separate C9300 network module and matching optics or copper media.

- C9300-24UXB-E vs C9300-24UXB-A is mainly a license split: both entries use the higher-scale 24UXB mGig UPOE hardware, but the `-E` SKU is Network Essentials and the `-A` SKU is Network Advantage.
- A C9300-24UXB-E vs C9300-24UX-E comparison keeps the 24-port mGig UPOE access requirement constant, then separates the higher-scale 24UXB buffer and 112,000-route profile from the standard 24UX model.
- C9300-24UXB-E vs C9300-24UB-E is a speed-profile comparison, because the UXB model gives 100M through 10G multigigabit UPOE access while the UB model stays on 10/100/1000 UPOE access.
- For C9300-24UXB-E vs C9300-48UB-E, the difference is port role and count: the current SKU is the 24-port mGig option, while C9300-48UB-E is the 48-port 1G UPOE Essentials alternative.
Selection Guide
1. Lock the license suffix first
Select C9300-24UXB-E only when the order calls for the 24UXB higher-scale switch with Network Essentials.
2. Treat Advantage as a separate line
Move to C9300-24UXB-A when the same mGig UPOE hardware must be paired with Network Advantage.
3. Check whether higher-scale is required
Keep C9300-24UX-E out of the quote if the requirement includes the 24UXB higher-scale buffer and route table profile.
4. Do not mix mGig and 1G access profiles
Use C9300-24UB-E or C9300-48UB-E only for higher-scale Network Essentials orders that need 1G UPOE ports instead of mGig UPOE ports.
PoE Power Planning
|
Planning Item |
Cisco Confirmed Value |
Order Impact |
|---|---|---|
|
Default PoE budget |
C9300-24UXB 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 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
|
Check Item |
What to Confirm |
Order Risk Controlled |
|---|---|---|
|
Exact hardware SKU |
C9300-24UXB-E on the switch line |
Prevents accidental substitution with the Advantage SKU, the standard 24UX line, or a 1G UPOE model |
|
License and subscription |
Network Essentials plus the matching Catalyst Essentials 24-port term license |
Keeps the hardware suffix and software subscription tier aligned |
|
Higher-scale stack plan |
Higher-scale Catalyst 9300 members, same license level, and StackWise cable length |
Avoids unsupported mixed stacking with standard modular-uplink C9300 hardware |
|
Uplink module |
Required C9300 network module and matching media |
Ensures the base switch order includes the intended uplink speed and connector path |
|
PoE and power supplies |
Default PWR-C1-1100WAC-P, 560W base PoE budget, and any secondary supply |
Aligns powered endpoint demand with the Cisco-listed power matrix |
|
Site cabling and fulfillment |
Copper category for 5G or 10G links, power cord region, price request, availability check, warranty support, and destination |
Keeps commercial processing tied to the confirmed hardware and deployment limits |
