C9300-48UN-E Description

C9300-48UN-E is a Cisco Catalyst 9300 Series stackable access switch with the Network Essentials license, built for campus access networks that need high-speed copper connectivity and centralized switch stacking. This order line defines a 48-port 100M/1G/2.5G/5G multigigabit Cisco UPOE switch with a modular uplink slot for Catalyst 9300 network modules, the default PWR-C1-1100WAC-P power supply, a 645W default PoE budget, and support for StackWise-480 and StackPower, with Cisco IOS XE Fuji 16.8.1a introducing the C9300-48UN hardware family.

Key Features

Network Essentials C9300-48UN order path

The `-E` suffix identifies the Network Essentials order line for the C9300-48UN hardware profile, separate from the Network Advantage C9300-48UN-A line.

5G multigigabit on every access port

The C9300-48UN model gives all 48 copper downlinks a 100M, 1G, 2.5G, or 5G access path with Cisco UPOE power.

Modular uplink bill of materials

The base switch uses a C9300 network-module slot, and Cisco ordering guidance allows a C9300 network module selection or a no-module selection.

StackWise-480 access stack member

C9300-48UN belongs to the modular-uplink Catalyst 9300 family with StackWise-480, so stack cable length and stack member planning remain part of the order review.

UPOE power planning point

The default PWR-C1-1100WAC-P supply gives a Cisco-listed 645W PoE budget, with higher PoE values available only when the secondary supply plan is selected correctly.

Software baseline guardrail

Cisco IOS XE Fuji 16.8.1a introduced the C9300-48UN hardware, so image baseline checks should be kept separate from older 1G-only Catalyst 9300 deployments.

Application Scenarios

Wi-Fi access with 5G copper

C9300-48UN-E fits an access closet where AP or endpoint links need 2.5G or 5G copper on any of the 48 access ports while the network license remains Essentials.

Essentials-tier mGig stack expansion

Use this SKU when the stack design calls for Catalyst 9300 modular uplinks, StackWise-480, and Network Essentials rather than the Advantage license suffix.

Separate uplink and power selection

The switch is appropriate when downlink speed is fixed at all-port 5G mGig UPOE, but the final quote still needs the C9300 network module, power supply set, and stack accessories selected as separate lines.

  • C9300-48UN-E vs C9300-48UN-A is a license comparison: both rows keep the 48-port 5G mGig UPOE hardware, 645W default PoE value, and StackPower support, while the current SKU is Network Essentials.
  • In a C9300-48UN-E vs C9300-48UXM-E comparison, the difference is the downlink layout: C9300-48UN-E keeps 5G multigigabit access on all 48 ports, while C9300-48UXM-E mixes 36 2.5G ports with 12 10G-capable mGig ports.
  • C9300-48UN-E vs C9300-24UX-E is a port-count comparison for Essentials mGig access, because C9300-24UX-E has 24 10G-capable mGig UPOE ports and the current SKU has 48 5G mGig UPOE ports.
  • For C9300-48UN-E vs C9300-48U-E, the which model to choose question starts with access speed: the current SKU is the 5G mGig UPOE model, while C9300-48U-E stays on 1G UPOE access.

Selection Guide

1. Choose it for all-port 5G mGig access

Select C9300-48UN-E when the BOM calls for 48 Catalyst 9300 copper access ports that can operate at 5G with Cisco UPOE.

2. Change to Advantage by suffix

Move to C9300-48UN-A only when the same C9300-48UN hardware must be ordered with Network Advantage instead of Network Essentials.

3. Keep UXM separate from UN

Use C9300-48UXM-E when the design specifically needs the mixed 36-port 2.5G plus 12-port 10G-capable layout rather than 48 ports of 5G mGig access.

4. Do not substitute a 1G UPOE switch

Keep C9300-48U-E out of the quote when the requirement names 2.5G or 5G copper access, because its access-port profile is 10/100/1000 UPOE.

PoE Power Planning

Planning Item

Cisco Confirmed Value

Order Impact

Default PoE budget

C9300-48UN is listed with 645W available PoE and PWR-C1-1100WAC-P as the default supply

Check endpoint power demand before assuming the default supply set is enough

Secondary supply options

The current data sheet lists 995W with a 350W secondary supply, 1360W with a 715W secondary supply, and 1745W with an 1100W secondary supply

Add the secondary supply that matches the powered-device plan and redundancy requirement

UPOE port class

Cisco UPOE ports support Type 1, Type 2, Type 3, and Cisco UPOE powered devices up to 60W per port

Prevents accidental replacement with data-only, PoE+, UPOE+, or 1G-only access models

StackPower design

Catalyst 9300 modular-uplink switches support StackPower

Include StackPower cabling only where the access stack design uses shared power

Uplink module

Required C9300 network module or no-module selection

Ensures the base switch order includes the intended uplink connector and speed path

PoE supply set

Default PWR-C1-1100WAC-P, secondary supply requirement, and StackPower cable use

Matches endpoint draw and redundancy requirements to Cisco-listed power values
