What is Cisco C9300-48U-A designed for?

Cisco C9300-48U-A is designed for 48-port Gigabit UPOE access with modular uplinks, StackWise-480, StackPower, and Network Advantage licensing. It fits high-power access closets that also need Advantage-level Layer 3 and policy features.

How is C9300-48U-A different from C9300-48U-E?

C9300-48U-A includes Network Advantage, while C9300-48U-E includes Network Essentials. Both are 48-port UPOE models, so the main decision is software capability.

How is C9300-48U-A different from C9300-48P-A?

C9300-48U-A provides UPOE, while C9300-48P-A provides PoE+. Choose C9300-48U-A when the access closet needs higher-power endpoint support across a 48-port model.

Can C9300-48U-A power access points and collaboration devices?

Yes. C9300-48U-A can power UPOE-capable endpoint types such as higher-power access points and collaboration devices when the power budget is planned correctly. Endpoint wattage and power supply redundancy should be checked before deployment.

What uplink modules should be considered for C9300-48U-A?

C9300-48U-A can use Catalyst 9300 modular uplinks, and 10G or faster modules are often appropriate for high-density powered access closets. The uplink module should match the expected aggregate traffic load.

Does C9300-48U-A support StackPower?

Yes. C9300-48U-A supports StackPower, which is valuable when many high-power endpoints depend on the access stack. Power sharing and redundancy mode should be chosen intentionally.

When should I choose C9300-24UX-A instead of C9300-48U-A?

Choose C9300-24UX-A when the site needs multigigabit UPOE access for fewer high-speed endpoints. Choose C9300-48U-A when the priority is 48 UPOE-capable 1G access ports.

When is C9300-48U-A more than the site needs?

C9300-48U-A may be more than the site needs if endpoints only require standard PoE+ or the software tier can stay at Network Essentials. C9300-48P-A or C9300-48U-E may be a cleaner fit.

C9300-48U-A Description

C9300-48U-A is a Cisco Catalyst 9300 Series stackable campus access switch with 48 10/100/1000 Cisco UPOE copper ports for high-density edge deployments that need modular uplinks and Network Advantage licensing. Cisco documents this model with UPOE support up to 60W per port, StackWise-480 and StackPower for resilient stack design, and an 822W default PoE budget in the standard power configuration.

Key Features

Network Advantage C9300-48U SKU

The `-A` suffix identifies this order line as the Network Advantage version of the 48-port 1G Cisco UPOE Catalyst 9300 switch.

60W UPOE access ports

Cisco UPOE ports support Type 1, Type 2, Type 3, and Cisco UPOE powered devices up to 60W per port, which separates C9300-48U-A from PoE+ and UPOE+ alternatives.

Field-selectable uplink module

The base switch uses a C9300 modular uplink slot, with Cisco ordering information listing 1G SFP, 10G SFP+, 25G SFP28, 40GE QSFP+, and multigigabit copper module choices.

Default 1100W AC power supply

The C9300-48U PoE budget is tied to the 1100W AC supply line, so endpoint power draw and redundancy should be reviewed before finalizing the secondary supply.

StackWise-480 access stack role

StackWise-480 support places this SKU in the modular-uplink Catalyst 9300 stack family rather than the fixed-uplink C9300L stack family.

Advantage subscription alignment

The hardware license suffix should be matched with Cisco Catalyst Advantage or Cisco DNA Advantage 48-port term licensing during the order build.

Application Scenarios

60W endpoint access refresh

C9300-48U-A fits a 1G access closet where phones, access points, cameras, or other powered endpoints need Cisco UPOE instead of data-only or PoE+ switching.

Advantage-tier Catalyst stack expansion

Use this SKU when an existing modular-uplink Catalyst 9300 stack needs another 48-port 1G UPOE member and the license tier must remain Network Advantage.

Uplink module controlled by the BOM

The switch is appropriate when downlink requirements are fixed at 48 1G UPOE ports but the uplink choice still needs to be selected through a C9300 network module.

C9300-48U-A vs C9300-48U-E is a license comparison: both use the 48-port 1G UPOE hardware profile, but the current SKU is Network Advantage and the `-E` SKU is Network Essentials.
In a C9300-48U-A vs C9300-48H-A comparison, the shared license tier is Network Advantage; the table difference is UPOE on C9300-48U-A versus UPOE+ on C9300-48H-A.
C9300-48U-A vs C9300-48P-A should be checked by powered-port class and default PoE budget, because the P model is the PoE+ alternative with a lower listed base budget.
For C9300-48U-A vs C9300-48UN-A, the current SKU is the 48-port 1G UPOE choice, while C9300-48UN-A is the 48-port 5G multigigabit UPOE model with a different capacity profile.

Selection Guide

1. Keep it for 48-port UPOE Advantage access

Choose C9300-48U-A when the BOM requires 48 1G copper access ports, Cisco UPOE, modular uplinks, and Network Advantage.

2. Use Essentials only when the license tier changes

Move to C9300-48U-E only when the same C9300-48U hardware profile is acceptable with Network Essentials instead of Network Advantage.

3. Separate UPOE from UPOE+ requirements

Select C9300-48H-A instead of C9300-48U-A only when the powered-device plan specifically calls for the UPOE+ hardware class.

4. Check speed before choosing a multigigabit model

Use C9300-48UN-A when 2.5G or 5G access speed is required; keep C9300-48U-A when 1G copper UPOE access is the confirmed requirement.

PoE Power Planning

Planning Item	Cisco Confirmed Value	Order Impact
UPOE class	Cisco UPOE ports support Type 1, Type 2, Type 3, and Cisco UPOE powered devices up to 60W per port	Confirm endpoint power class instead of quoting a PoE+ or UPOE+ model by habit
Default PoE budget	C9300-48U is listed with 822W available PoE and a PWR-C1-1100WAC-P default supply	Compare powered endpoint count with the available base budget
Power supply slots	Catalyst 9300 switches support one or two internal power supply modules	Decide whether the secondary supply is needed for redundancy, more available PoE, or both
StackPower design	Catalyst 9300 modular-uplink switches support StackPower	Add StackPower cabling only when the deployment uses shared power across stack members

Ordering Checklist

Check Item	What to Confirm	Why It Matters
Exact switch SKU	C9300-48U-A on the hardware line	Avoids substitution with the Essentials `-E` SKU, the UPOE+ `C9300-48H` line, or the PoE+ `C9300-48P` line
Uplink module	C9300-NM-8X default selection or another approved C9300 network module	Prevents the base switch from being selected with the wrong uplink media or without the intended uplink module
Software subscription	Cisco Catalyst Advantage or Cisco DNA Advantage 48-port term license	Keeps the term software order aligned with the Network Advantage hardware suffix
Stacking accessories	StackWise cable length and StackPower cable selection	Matches the physical stack design to the intended Catalyst 9300 deployment
