C9300-48U-E Description

C9300-48U-E is a Cisco Catalyst 9300 Series stackable access switch built for campus edge deployments that need 48 10/100/1000 Cisco UPOE copper ports, a modular uplink slot for Catalyst 9300 network modules, the Network Essentials license tier, an 822W default PoE budget, and StackWise-480 with StackPower support for resilient high-density access switching.

Key Features

Essentials license on 48-port UPOE hardware

The `-E` suffix places this C9300-48U Catalyst 9300 model in the Network Essentials order path while keeping the same 48-port UPOE chassis profile used by the `-A` license variant.

1G copper access with Cisco UPOE

The `C9300-48U` model identity separates this SKU from data-only, PoE+, UPOE+, and multigigabit Catalyst 9300 access switches.

Uplink selected through the module line

C9300 modular-uplink switches use field-replaceable C9300 network modules, and Cisco ordering guidance allows the module selection to be changed or omitted.

822W base PoE planning point

Cisco lists 822W available PoE for C9300-48U with the default power supply path, which makes the endpoint power worksheet a required pre-quote check.

StackWise-480 stack member

The switch belongs to the modular-uplink C9300 stack family with StackWise-480, so stack member family and cable length should be confirmed with the existing access stack.

StackPower accessory boundary

C9300 switches support StackPower cabling, but the order should include StackPower cables only when the site design uses redundant or power-sharing stack power.

Application Scenarios

High-density UPOE access closet

C9300-48U-E fits a wiring closet that needs 48 1G copper downlinks with Cisco UPOE while keeping the campus software tier at Network Essentials.

Essentials-tier stack refresh

The SKU can refresh or expand a modular-uplink Catalyst 9300 access stack when the BOM stays on Network Essentials rather than moving to Network Advantage.

Separate uplink and power selection

This model works when downlink count and UPOE class are fixed, but the final order still needs a C9300 network module, StackWise cable, StackPower cable, and power supply plan selected as separate lines.

  • In a C9300-48U-E vs C9300-48U-A comparison, the table shows the same 48-port UPOE hardware profile, StackWise-480 support, 822W default available PoE, and software baseline; the difference is Network Essentials versus Network Advantage.
  • The C9300-48U-E difference from C9300-48P-E is powered-port class and power budget, because C9300-48P-E is the PoE+ model with 437W default available PoE.
  • For C9300-48U-E vs C9300-48H-E, the comparison turns on UPOE versus UPOE+ while the listed default available PoE value remains 822W.
  • C9300-48U-E vs C9300-48UN-E should be checked by access speed and capacity, since C9300-48UN-E is the 5G multigigabit UPOE option with different switching and forwarding figures.

Selection Guide

1. Select it for Essentials 48-port UPOE access

C9300-48U-E belongs in a BOM that requires 48 1G Cisco UPOE access ports, modular uplinks, and Network Essentials on the hardware order.

2. Change only the license suffix for Advantage

Move to C9300-48U-A when the access port and PoE profile stay the same but the approved network license tier is Network Advantage.

3. Do not replace it with a PoE+ model by habit

Choose C9300-48P-E only when PoE+ is enough for the powered endpoints and the lower listed default PoE budget is acceptable.

4. Check multigigabit demand before switching families

Use C9300-48UN-E when the design needs 2.5G or 5G copper access; keep C9300-48U-E when 1G copper UPOE is the confirmed requirement.

PoE Power Planning

Planning Item

Cisco Confirmed Value

Order Impact

Default PoE budget

C9300-48U is listed with 822W available PoE

Compare powered endpoint count and draw against the installed power supply plan

UPOE class

Catalyst 9300 UPOE power planning covers Cisco UPOE 60W per port for supported UPOE models

Verify whether endpoints need UPOE instead of PoE+ or UPOE+

48-port UPOE full-power supply set

Cisco lists two PWR-C1-1100WAC or PWR-C1-1100WAC-P supplies for 48-port UPOE power planning

Add the correct supply set when many endpoints need high-power UPOE

StackPower design

C9300 switches support StackPower cables for redundant or power-sharing stack power

Include StackPower cables only when the access stack design uses shared power

Ordering Checklist

Check Item

What to Confirm

Why It Matters

Exact switch SKU

C9300-48U-E

Confirms the order is the 48-port Catalyst 9300 UPOE model with Network Essentials

Uplink module

C9300-NM module choice or C9300-NM-NONE

The C9300 base switch uses modular uplinks and the order can change or omit the default module selection

License term

Cisco Catalyst Essentials or Cisco DNA Essentials 48-port term license

Keeps the subscription line aligned with the Network Essentials hardware suffix

PoE design

822W default available PoE and the required 60W endpoint count

Prevents quoting a PoE+ or UPOE+ model when the endpoint class is different

Stack accessories

StackWise-480 cable length and StackPower cable selection

Matches the physical stack and power-sharing design to the deployment

Power accessories

Secondary power supply and regional power cords

Cisco ordering guidance includes power supply and cable selections that must match the site

Questions & Answers

  • What is Cisco C9300-48U-E used for?

    Cisco C9300-48U-E is used for 48-port Gigabit UPOE access with modular uplinks and Network Essentials licensing. It fits access closets where many endpoints need more power than standard PoE+ models provide.

  • What does U mean in C9300-48U-E?

    In C9300-48U-E, U indicates a UPOE access model. It is intended for higher-power endpoint deployments than standard PoE+ switches such as C9300-48P-E.

  • How is C9300-48U-E different from C9300-48P-E?

    C9300-48U-E provides UPOE capability, while C9300-48P-E provides PoE+. Choose C9300-48U-E when connected devices need higher power delivery than the 48P model is intended to provide.

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

    C9300-48U-E ships with Network Essentials, while C9300-48U-A ships with Network Advantage. The hardware role is aligned, so the decision is mainly the software tier required by the access design.

  • Can C9300-48U-E power high-power devices?

    Yes. C9300-48U-E is designed for UPOE endpoints, but the final powered-device count depends on power supply configuration, StackPower design, and endpoint wattage. Power planning is especially important on 48-port UPOE switches.

  • What uplink modules can C9300-48U-E use?

    C9300-48U-E supports Catalyst 9300 modular uplinks. Faster uplink modules are often useful because a 48-port UPOE access closet can aggregate many powered devices and VLANs.

  • Can C9300-48U-E use StackPower?

    Yes. C9300-48U-E supports StackPower, which can improve power resiliency for high-power access closets. The design should define whether StackPower is used for sharing, redundancy, or both.

  • When is C9300-48U-E not the best option?

    C9300-48U-E is not the best option when endpoints only need PoE+, multigigabit access, or Network Advantage by default. C9300-48P-E, C9300-24UX-E, or C9300-48U-A may be better choices.
