Shallow-Depth Powered Access for Enterprise Wiring Closets

C9300LM-24U-4Y-E is a shallow-depth, managed Layer 3 enterprise access switch with 24 Gigabit copper ports, Cisco UPOE and four fixed optical uplinks. The full-width 1U chassis belongs to the Catalyst 9300LM series within the Catalyst 9000 family. Network Essentials supplies the base feature set for powered access and limited routed-access requirements. Fixed uplinks mean the purchase does not require a removable network module, although the operating-speed discrepancy identified below needs resolution before optics are specified. The closest license variant, C9300LM-24U-4Y-A, carries Network Advantage for advanced routing requirements. This 24-port Gigabit UPOE access switch is therefore differentiated by its shallow chassis and perpetual Essentials tier, rather than by a modular uplink architecture.

Technical Details

248 Gbps switching capacity defines the hardware forwarding capacity, while 184.51 Mpps provides the separate packet-forwarding rate for packet-size-sensitive designs. 420W of shared PoE capacity requires endpoint power allocation rather than assuming every powered port can draw its individual maximum simultaneously. OSPF supports up to 1000 routes under Network Essentials; Static, RIP, EIGRP Stub, PBR, VRRP and PIM Stub complete the routed-access feature set. Full EIGRP, BGP and IS-IS require Network Advantage. C9300LM-24U-4Y-E combines 8 GB of DRAM, 16 GB of flash and a 16 MB packet buffer. Its UADP 2.0 forwarding silicon supports a 32000-entry MAC table and a total IPv4 hardware scale of 32000 entries, distinct from the license-specific OSPF limit. Cisco IOS XE provides the operating environment. Expired Cisco DNA add-ons can be deactivated; after a reload, the perpetual base capabilities remain available. StackPower is not supported on this fixed-uplink family.

Ordering

C9300LM-24U-4Y-E is available new sealed or certified refurbished; ORM's warranty is up to a 3-year extended warranty for new units and up to 1 year for certified refurbished units, with 30-day returns on every condition; terms apply. Refurbished units are inspected and bench-tested, with power-on and POST, rated-speed port links, clean boot, PoE output under load on every powered port, optics recognition, PSU and fan status, firmware verification and configuration wiped to factory default. Specify condition, power configuration, optics and licensing on the purchase order. For enterprise and volume orders, POs are accepted, Net-30 is available for government, and RMA includes advance replacement, with regional stock and RMA across the UK, EU, US and MEA.

Buying Notes

Buying NotesKey Specs

Select the subscription path

C9300LM-24U-4Y-E orders require subscription selection: Cisco DNA Essentials or Advantage and Cisco Catalyst Essentials or Advantage start at three years; Cisco Networking Subscription offers Cisco Switching Essentials or Advantage with a 36-month minimum.

Order compatible stacking hardware

C9300LM-24U-4Y-E requires C9300L-STACK-KIT2 for stacking, including STACK-T3A-50CM. Mix only Catalyst 9300L and Catalyst 9300LM members with matching license levels; modular-uplink Catalyst 9300 and Catalyst 9300X members cannot join.

Confirm the quoted uplink speed

C9300LM-24U-4Y-E needs uplink-speed confirmation: its September 23, 2026 datasheet specifies four 25G uplinks, while its September 1, 2026 ordering guide specifies four 10G SFP+ uplinks. Confirm the required active speed before ordering.

Verify PoE-loaded input power

C9300LM-24U-4Y-E needs power-configuration confirmation: its published 100% PoE test reaches 990.9W, exceeding the 600W rating of the standard PWR-C6-600WAC supply. Confirm the tested configuration before sizing branch circuits or UPS capacity.

Best For

Installed Estate Refresh

An installed estate of discontinued WS-C3650-24PDM-L switches creates a direct refresh requirement for the named replacement, rather than a search based only on port count. Treat the purchase as a separate hardware and entitlement configuration. Specify replacement quantities, new stacking accessories and required operating software before the PO.

Lab And Staging

A lab or staging purchase that depends on temporary advanced features needs an explicit licensing exit plan. The 90-day evaluation cannot be reactivated after expiration and reload. Separate evaluation testing from production entitlement, and specify which purchased feature set must remain enabled before the equipment moves into service.

Multi-Site License Allocation

A multi-site order using Smart Licensing needs the destination Smart Account established before entitlements are assigned. Keep hardware quantities and software ownership aligned across site-specific line items rather than treating activation as a receiving task. Specify the account destination and subscription allocation in the procurement instructions before releasing the PO.

Not Suitable If

BGP or full dynamic routing

Network Essentials excludes BGP, full EIGRP and IS-IS. C9300LM-24U-4Y-A provides Network Advantage for these requirements while retaining 24 Gigabit UPOE access ports.

Multigigabit copper access ports

The copper access ports stop at 1G. C9300LM-48UX-4Y-E adds eight Multigigabit access ports, but changes the total access-port density to 48 ports.

Questions & Answers

What does the C9300LM-24U-4Y-E part number mean?

C9300LM-24U-4Y-E identifies the Catalyst 9300 mini configuration: C9300LM denotes the mini family, 24 denotes 24 copper access ports, U denotes UPOE, 4Y denotes four fixed uplinks, and E denotes Network Essentials. The uplink speed requires separate confirmation because the current datasheet and ordering guide describe different speeds for this exact configuration.

How is C9300LM-24U-4Y-E managed?

C9300LM-24U-4Y-E supports WebUI and CLI management, including local console and SSH access. Cisco Catalyst Center provides centralized management through the applicable subscription. Meraki dashboard integration introduces cloud management and Cloud CLI options where supported by the selected software release and licensing configuration; confirm that combination before specifying a cloud-managed deployment.

Is the Catalyst 9300LM end of sale?

Cisco has not announced an end-of-sale date for Catalyst 9300LM. That statement concerns switch hardware, not retirement of individual software releases or stacking accessories. Specify the hardware PID separately from software and accessory line items so lifecycle requirements remain attached to the equipment being ordered rather than an unrelated release milestone.

What conditions and warranties does ORM Systems offer for C9300LM-24U-4Y-E?

C9300LM-24U-4Y-E is offered new sealed or certified refurbished, with ORM coverage up to a 3-year extended warranty for new units or up to 1 year for refurbished units. Both conditions have 30-day returns; terms apply. Cisco's Enhanced Limited Lifetime hardware warranty is separate, applies to eligible original owners, and remains subject to Cisco lifecycle limits.

Which licensing paths are available for C9300LM-24U-4Y-E?

C9300LM-24U-4Y-E includes perpetual Network Essentials. Cisco DNA Essentials and Cisco DNA Advantage, or Cisco Catalyst Essentials and Cisco Catalyst Advantage, use a minimum three-year term. Cisco Networking Subscription offers Cisco Switching Essentials or Cisco Switching Advantage with a 36-month minimum. Match subscription entitlement to the ordered network tier and verify licensing on refurbished orders.

Which older switch does C9300LM-24U-4Y-E replace?

C9300LM-24U-4Y-E replaces the discontinued WS-C3650-24PDM-L, whose end-of-sale date was May 31, 2023. Order the refresh as a separate hardware and licensing configuration rather than assuming the old switch's entitlement transfers. Confirm optics, stacking hardware and the required operating software independently when preparing the replacement purchase order.

How much PoE power does C9300LM-24U-4Y-E provide?

C9300LM-24U-4Y-E provides a shared 420W PoE budget with the standard PWR-C6-600WAC supply. Cisco UPOE supports a 60W per-port maximum, but that maximum is not available simultaneously on every port from the default budget. Adding a second PWR-C6-600WAC increases the available PoE budget to 1020W; size the endpoint allocation before ordering.

What uplink speed does C9300LM-24U-4Y-E support?

C9300LM-24U-4Y-E has four fixed optical uplinks, but the quoted operating speed needs confirmation. The September 23, 2026 datasheet specifies 25G; the September 1, 2026 ordering guide describes 10G SFP+ for the E variant. Obtain written confirmation of required speed, software tier and compatible optics before issuing the PO.

How many switches can a Catalyst 9300LM stack contain?

Catalyst 9300LM supports eight members through StackWise-320 at 320 Gbps. C9300L-STACK-KIT2 contains two adapters and STACK-T3A-50CM; STACK-T3A-1M and STACK-T3A-3M provide longer cable options. Stack partners must be Catalyst 9300L or Catalyst 9300LM models with matching license levels. Order the kit and cable lengths for the intended physical arrangement.

Which power supply ships with C9300LM-24U-4Y-E?

C9300LM-24U-4Y-E ships with PWR-C6-600WAC as its default primary supply, while a second internal supply is optional. Redundant power therefore requires a separate configuration decision rather than being assumed from the base PID. State the required supply quantity on the order and keep redundancy requirements separate from the endpoint power-budget calculation.

What is the difference between C9300LM-24U-4Y-E and C9300LM-48T-4Y-E?

C9300LM-24U-4Y-E supplies UPOE on 24 Gigabit access ports, whereas C9300LM-48T-4Y-E provides 48 data-only Gigabit access ports without endpoint power. The port count also changes, so the latter is not a like-for-like powered replacement. Choose the 24-port model for powered endpoints and the 48-port data model when endpoint power is supplied separately.

What is the difference between C9300LM-24U-4Y-E and C9300LM-24U-4Y-A?

C9300LM-24U-4Y-E includes Network Essentials, while C9300LM-24U-4Y-A includes Network Advantage. Network Advantage adds advanced routing such as BGP, full EIGRP and IS-IS beyond the Essentials routed-access feature set. The E model suits limited routed access; the A model suits buyers whose required routing features exceed those Essentials limits.

What is the difference between C9300LM-24U-4Y-E and C9300LM-48U-4Y-E?

C9300LM-48U-4Y-E provides 48 Gigabit UPOE access ports, compared with 24 on C9300LM-24U-4Y-E. Both configurations carry Network Essentials and belong to the shallow-depth mini family. Choose the 24-port configuration when that access density covers the purchase requirement; specify the 48-port configuration when the required copper connection count exceeds it.

Can C9300LM-24U-4Y-E perform Layer 3 routing?

Yes, C9300LM-24U-4Y-E performs Layer 3 routed access with Network Essentials, including OSPF limited to 1000 routes, Static, RIP and EIGRP Stub. PBR, VRRP and PIM Stub are also included. The 32000-entry IPv4 hardware total does not remove the OSPF license limit or grant advanced routing features excluded from Essentials.

Is the Catalyst 9300LM a full-width rack switch?

Yes, the Catalyst 9300LM configuration represented by C9300LM-24U-4Y-E is a full-width 1U rack switch, not a narrow desktop switch. Its dimensions with the default supply are 43 mm high, 444 mm wide and 334 mm deep. Allow additional installation space for attached cables rather than treating chassis depth as the complete cabinet clearance requirement.
