C9300-48U-A Description

C9300-48U-A is the Cisco Catalyst 9300 48-port 1G copper UPOE switch ordered with Network Advantage and a modular uplink slot. Cisco lists the model with StackWise-480, StackPower support, an 822W default PoE budget, and Cisco IOS XE Everest 16.5.1a as the minimum software release.

Keep this SKU separate from C9300-48U-E when the hardware requirement stays on the 48U UPOE line but the license tier must be Advantage instead of Essentials. It also differs from C9300-48H-A because the 48H model is the UPOE+ option, not the 60W UPOE hardware line.

Procurement review should pin down the selected C9300 network module, Advantage subscription term, Smart Account, StackWise cable, StackPower cable, secondary power supply, regional power cord, endpoint power class, price request, availability check, warranty support, and shipping destination.

Key Features

Network Advantage 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 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 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

Order Risk Controlled

Exact switch SKU

C9300-48U-A on the hardware line

Avoids substitution with the Essentials `-E` SKU, the UPOE+ `48H` line, or the PoE+ `48P` line

Uplink module

C9300-NM-8X default selection or another approved C9300 network module

Prevents the base switch from being quoted 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

PoE and power supplies

822W base PoE budget, PWR-C1-1100WAC-P supply, and secondary power supply choice

Controls endpoint power planning before the final quote is released

Stacking accessories

StackWise cable length and StackPower cable selection

Matches the physical stack design to the intended Catalyst 9300 deployment

Fulfillment details

Smart Account, regional power cord, price request, availability check, warranty support, and shipping destination

Questions & Answers

  • 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.
