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

Network Essentials 24UXB order line

C9300-24UXB-E combines the higher-scale 24UXB hardware profile with Network Essentials, making it the Essentials counterpart to C9300-24UXB-A.

All-port mGig UPOE access

The downlink block is 24 multigigabit copper ports that support 100M, 1G, 2.5G, 5G, and 10G operation with Cisco UPOE.

Higher-scale buffer and tables

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.

Modular uplink decision

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.

Restricted higher-scale stacking

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.

Power plan before endpoint count

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

Essentials-tier Wi-Fi access refresh

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.

Higher-scale mGig stack expansion

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.

Modular-uplink access aggregation

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

Questions & Answers

  • Who needs C9300-24UXB-E for higher-scale 10G/mGig UPOE and Network Essentials?

    C9300-24UXB-E fits higher-scale 24-port 10G/mGig copper access that needs UPOE power and Network Essentials scope.
  • What does UXB mean for C9300-24UXB-E higher-scale UPOE access?

    C9300-24UXB-E combines higher-scale C9300 hardware, 24 10G/mGig copper downlinks, UPOE power, and modular uplinks.
  • Can C9300-24UXB-E stack with 24UB higher-scale switches?

    Yes. C9300-24UXB-E can join higher-scale peers, adding 10G/mGig UPOE access ports beside 1G UPOE members such as C9300-24UB-E.
  • Can C9300-24UXB-E stack with standard C9300 or higher-scale models?

    No. C9300-24UXB-E needs higher-scale stack peers and is not for mixed stacking with standard C9300 models.
  • How is C9300-24UXB-E different from C9300-24H-E?

    C9300-24UXB-E provides 10G/mGig copper UPOE and higher-scale stacking. C9300-24H-E provides 1G copper UPOE+ for 90W endpoint power.
  • Can C9300-24UXB-E use modular uplinks in higher-scale StackWise?

    C9300-24UXB-E is the Network Essentials version. Use C9300-24UXB-A for the same higher-scale mGig hardware with Network Advantage.
  • When is C9300-24UXB-E the wrong SKU?

    C9300-24UXB-E is wrong for standard C9300 stacks, 1G-only access, fiber access, or 90W UPOE+ designs.
  • What higher-scale, power, and modular uplink details matter for C9300-24UXB-E?

    C9300-24UXB-E planning depends on 24 10G/mGig ports, UPOE load, higher-scale stack membership, Network Essentials scope, power pool, and modular uplinks.
