C9300LM-24U-4Y-E Description

The C9300LM-24U-4Y-E is a Cisco Catalyst 9300LM mini fixed-uplink access switch, built on the reduced-depth 9300LM chassis with 24 Cisco UPOE copper ports, 4x 25G SFP28 fixed uplinks, and a Network Essentials license. The 9300LM sub-line runs on its own PWR-C6 power series, and here the default PWR-C6-600WAC supply gives 420W of PoE without a second supply, extending to 1420W with a PWR-C6-1KWAC secondary supply. Network Essentials on this hardware covers Layer 2 switching, routed access with up to 1000 OSPF routes, PIM stub multicast, VRRP, 802.1X, and MACsec-128, which matches straightforward access-layer designs that do not need the routing scale or segmentation features gated behind Network Advantage. Stacking uses StackWise-320 and can mix with Catalyst 9300L members holding the same license tier, keeping this SKU inside the shallow-chassis fixed-uplink hardware line rather than the modular-uplink Catalyst 9300 or 9300X platforms.

Key Features

Layer 2 access on a mini chassis

The 13.03 in chassis-only depth of the Catalyst 9300LM line brings Network Essentials access switching into shallow racks that reject full-depth Catalyst 9300 hardware.

PWR-C6-only power planning

Second-supply and spare-parts orders stay inside the PWR-C6-600WAC/PWR-C6-1KWAC pair, since this chassis rejects every PWR-C1 supply used elsewhere in the Catalyst 9300 family.

420W PoE ceiling without upgrade

The default PWR-C6-600WAC supply caps available Cisco UPOE power at 420W until a second or upgraded PWR-C6-1KWAC supply is added, a fixed planning number for closets that stay on the default supply.

Network Essentials feature set

This SKU carries Layer 2 switching, routed access up to 1000 OSPF routes, PIM stub multicast, VRRP, 802.1X, and MACsec-128, covering standard access-layer designs without the VRF, VXLAN, or MACsec-256 entitlements reserved for Network Advantage.

StackWise-320 mini-line stacking

StackWise-320 lets this switch stack with other Catalyst 9300L or 9300LM members at a matching license tier, so an Essentials-only stack plan stays consistent across the fixed-uplink hardware line.

RJ-45 management plane with USB console priority

Out-of-band management runs through a 10/100/1000 RJ-45 Ethernet management port plus an RJ-45 console port, and when a USB mini-Type B console cable is also connected, the USB console takes priority automatically, so a technician does not need to physically disconnect the RJ-45 console cable to switch to USB for local access.

Application Scenarios

Shallow-Depth Access Closet

Installed in shallow wall-mount cabinets or low-depth enclosures where a full-depth Catalyst 9300 chassis will not fit, while still delivering Cisco UPOE power to access endpoints.

Layer 2 Edge With Basic Routed Access

Deployed at branch or edge access points that only need Layer 2 switching, limited-route OSPF, or PIM stub multicast, without the VRF or VXLAN segmentation gated behind Network Advantage.

Essentials-Tier Stack Expansion

Added to an existing StackWise-320 ring of Catalyst 9300L or 9300LM members that already standardizes on Network Essentials, extending UPOE and 25G uplink capacity without changing the stack’s license tier.

  • C9300LM-24U-4Y-E and C9300LM-24U-4Y-A share identical hardware, so the choice between them is a license question, not a port or power question: both hold the same 420W default PoE budget, 4x 25G fixed uplinks, and 248 Gbps switching capacity, and only the Network Advantage feature set of VRF, VXLAN, Cisco TrustSec, and MACsec-256 separates the two SKUs.
  • Moving from this SKU to C9300L-24UXG-4X-E gives up the mini chassis depth in exchange for more PoE headroom and Multigigabit access, since the C9300L-24UXG-4X-E default supply budgets 880W against 420W here and adds 8 Multigigabit ports; a design that needs that PoE ceiling or Multigigabit endpoint speed has to move to the deeper hardware regardless of license tier.
  • For deciding which SKU to order in this group, confirm the routing and segmentation requirement first: if VRF, VXLAN, or MACsec-256 is required, C9300LM-24U-4Y-A is the only option in this table that adds it without changing chassis depth, and if that requirement is absent, this Essentials SKU keeps the identical hardware at the lower license tier.

Selection Guide

1. Essentials Covers Layer 2 And Limited Routing

C9300LM-24U-4Y-E carries Network Essentials, which is enough when the deployment needs only Layer 2 switching, up to 1000 OSPF routes, PIM stub multicast, or VRRP on the mini fixed-uplink hardware, avoiding the Network Advantage premium for features the design does not use.

2. Upgrade Path When Segmentation Is Added Later

Cisco’s ordering guide ties Network Essentials and Network Advantage to separate orderable PIDs; there is no in-place upgrade PID from C9300LM-24U-4Y-E to C9300LM-24U-4Y-A, so a design that expects to add VRF, VXLAN, or MACsec-256 within the hardware’s service life should order C9300LM-24U-4Y-A up front instead of planning a later license swap.

3. Mini Depth Before Higher PoE Draw

The 420W default PoE budget on this mini chassis sits well below the 880W on C9300L-24UXG-4X-E; an access design with heavier Multigigabit or high-draw UPOE endpoints needs the deeper C9300L-24UXG-4X-E hardware rather than a license change on this SKU.

4. License Tier Must Match Across Stack Members

When this switch stacks with Catalyst 9300L members over StackWise-320, every member’s Network Stack license tier must match Network Essentials; a stack partner already running Network Advantage requires aligning the whole ring to one tier before the stack forms correctly.

Ordering Checklist

Check Item

What to Confirm

Why It Matters

License suffix

Confirm the order specifies C9300LM-24U-4Y-E and not the C9300LM-24U-4Y-A Advantage PID.

Ordering the wrong suffix pays for entitlements the Essentials-tier design does not use.

Power supply family

Confirm only PWR-C6-600WAC or PWR-C6-1KWAC appears on the bill of materials.

PWR-C1 supplies used elsewhere in the Catalyst 9300 family are not compatible with this chassis.

Second power bay

Confirm a blank module or a second PWR-C6 supply is specified for the empty bay.

An empty bay without a blank module can affect airflow and fan noise levels.

Smart Account binding

Confirm the target Smart Account and Virtual Account before the order is placed.

The Network Stack license and software subscription are tied to Smart Licensing and cannot activate without a bound account.

Subscription tier match

Confirm the Cisco Catalyst, Cisco DNA, or Meraki subscription selected is the Essentials tier, matching the hardware license.

A Network Advantage hardware SKU paired with an Essentials subscription is only permitted at renewal, not on a new order, and a mismatch on this SKU can misalign future upgrade planning.

Stack partner license tier

Confirm any Catalyst 9300L stack partner also runs Network Essentials.

StackWise-320 mixing between C9300L and C9300LM requires a matching license tier across members.

Questions & Answers

  • Can C9300LM-24U-4Y-E power Wi-Fi 6 access points without a separate injector?

    C9300LM-24U-4Y-E has 24 1G copper UPOE ports, so access points that fit Cisco UPOE power draw can run from the switch within the available power budget.

  • Why would C9300LM-24U-4Y-E be chosen for a shallow rack?

    C9300LM-24U-4Y-E is an LM mini, shallow-depth Catalyst 9300 model, useful where a 24-port UPOE access switch has to fit a tight cabinet or wall rack.

  • Are the four uplinks on C9300LM-24U-4Y-E replaceable modules?

    C9300LM-24U-4Y-E uses four fixed 25G SFP28 uplinks; it does not take C9300 network modules, so uplink speed planning happens before purchase.

  • What does the E suffix change on C9300LM-24U-4Y-E?

    The E suffix maps C9300LM-24U-4Y-E to Network Essentials, while the hardware remains 24 UPOE ports, four 25G fixed uplinks, and StackWise-320.

  • Can C9300LM-24U-4Y-E use 1G copper SFP transceivers in the uplinks?

    C9300LM-24U-4Y-E SFP28 uplinks need transceiver and IOS XE checks; a Cisco Community case reported GLC-TE link issues on 17.09.03 that were fixed in 17.09.05.

  • What power-supply detail is easy to miss on C9300LM-24U-4Y-E?

    C9300LM-24U-4Y-E ships with a 600W AC class supply, and Cisco notes C9300LM models use different power supplies from C9300, C9300X, and C9300L models.

  • How does C9300LM-24U-4Y-E stack with other Catalyst 9300 models?

    C9300LM-24U-4Y-E belongs to the fixed-uplink LM family with StackWise-320, so mixed-stack planning needs bandwidth, software, license, and hardware checks.

  • Which ordering mistake affects C9300LM-24U-4Y-E most often?

    C9300LM-24U-4Y-E orders go wrong when teams expect modular uplinks, mGig downlinks, or Network Advantage features; this SKU is fixed-uplink, 1G UPOE, Network Essentials.
