C9300LM-48T-4Y-A combines a shallow-depth rack-mount 1U chassis with managed Layer 3 enterprise access switching, 48 Gigabit copper data ports, and four fixed 25G SFP28 uplinks. The Catalyst 9300LM configuration supplies Network Advantage and is non-PoE, so attached equipment needs its own power source. C9300LM-48U-4Y-A adds Cisco UPOE for powered endpoints. Within the Cisco Catalyst 9300 family, fixed uplinks keep the distribution connection separate from the copper access specification; there is no removable network-module bay for later uplink expansion.
C9300LM-48T-4Y-A price for new stock is $8,347.50. C9300LM-48T-4Y-A refurb price is $6,170.85. C9300LM-48T-4Y-A is in stock and available for next-day dispatch. (terms applied)

296 Gbps switching capacity and 220.22 Mpps forwarding rate define the standalone traffic limits for sizing the access edge. 616 Gbps switching capacity with stacking applies when the optional hardware stack is assembled, not to a standalone deployment. OSPF, EIGRP, BGP, and IS-IS provide dynamic routing under the supplied network license, with PBR and VRRP available for policy and gateway functions. C9300LM-48T-4Y-A carries 8 GB DRAM and 16 GB flash for its control plane and local image storage. A 16 MB packet buffer handles transient traffic queues, while 32000 MAC entries set the address-table ceiling. IPv4 capacity totals 32000 routes, split into 24000 direct and 8000 indirect entries. Cisco IOS XE runs on Cisco UADP 2.0 forwarding silicon. 101.4W measured consumption under full-port traffic at 115V AC informs the electrical load estimate; PWR-C6-600WAC is the supplied power module, not the switch’s measured draw. A second internal supply is optional rather than standard.
C9300LM-48T-4Y-A is available new sealed or certified refurbished, with ORM’s new extended warranty up to 3 years, refurbished warranty up to 1 year, and 30-day returns on either condition; terms apply. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed port links, optics bay recognition, and clean boot; firmware is verified and configurations wiped to factory default. Specify condition, quantity, licensing, and accessories on the PO; Cisco’s separate Enhanced Limited Lifetime hardware warranty applies to the original customer, with a five-year post-discontinuance bound. Enterprise and volume orders accept POs, Net-30 for government, and RMA with advance replacement across UK, EU, US, and MEA.

When a wiring-closet refresh moves inter-VLAN gateways onto the access switch, the design must account for a ceiling of 1000 switched virtual interfaces. Keep gateway placement and interface allocation in the migration plan, then specify the required interface count and compatible software configuration before the PO.
When extending an existing hardware stack, modular-uplink Catalyst 9300 and Catalyst 9300X members cannot join this fixed-uplink model. Identify the installed chassis family rather than relying on the Catalyst name alone. Specify a compatible fixed-uplink member set and verify the existing stack inventory before the PO.
When staging switches for a repeatable site rollout, the embedded WebUI can build and validate device configurations without a separately enabled WebUI license. Keep the device-management method separate from subscription-based automation. Specify the staging configuration, software entitlement, and acceptance checks before releasing the purchase order.
PoE-powered endpoint connections
C9300LM-48T-4Y-A supplies no endpoint power. C9300LM-48U-4Y-A provides Cisco UPOE across 48 Gigabit ports when the purchase requires power delivery over copper.
Multigigabit speeds on copper downlinks
C9300LM-48T-4Y-A limits copper access connections to 1G. C9300LM-48UX-4Y-A adds eight Multigigabit copper ports while retaining 40 Gigabit copper ports.

C9300LM-48T-4Y-A identifies a Catalyst 9300 mini switch: C9300LM is the mini model prefix, 48 denotes 48 access ports, T denotes 1G copper data ports, 4Y denotes four 25G uplinks, and A denotes Network Advantage. The data-port marker distinguishes this configuration from the powered copper versions.
The Catalyst 9300LM supports CLI management through the local console or SSH, an embedded WebUI, and Cisco Catalyst Center integration. WebUI ships with the default image and needs no separate activation license. Specify the management subscription separately when centralized automation or assurance is required.
C9300LM-48T-4Y-A supports Cisco DNA, Cisco Catalyst Software, and Cisco Networking Subscription licensing. DNA and Catalyst offer Essentials and Advantage with three-year minimums; new orders match Network Advantage with Advantage. Unified licensing offers Cisco Switching Essentials or Cisco Switching Advantage with a 36-month minimum. Network Advantage remains perpetual under the DNA/Catalyst path.
C9300LM-48T-4Y-A retains its perpetual Network Advantage capabilities after the Cisco DNA or Cisco Catalyst add-on expires. Renew the term entitlement to keep subscription features, or deactivate the expired add-on and reload the switch for base-license operation. Keep the Smart Account entitlement and renewal decision separate from the hardware condition.
Cisco has not announced an end-of-sale date for Catalyst 9300LM. Switch hardware, IOS XE software releases, and stacking accessories have separate lifecycles. An accessory retirement does not discontinue C9300LM-48T-4Y-A. Specify the hardware PID, required software release, and subscription entitlement separately when arranging support for the order.
ORM offers C9300LM-48T-4Y-A new sealed or certified refurbished, with new extended warranty up to three years and refurbished warranty up to one year. Both conditions have 30-day returns; terms apply. Cisco’s separate Enhanced Limited Lifetime hardware warranty covers the original customer, subject to five-year post-discontinuance limits, and is not the refurbished order warranty.
StackWise-320 stacks eight Catalyst 9300LM members at 320 Gbps using C9300L-STACK-KIT2. The kit includes two adapters and STACK-T3A-50CM; STACK-T3A-1M and STACK-T3A-3M provide longer connections. Catalyst 9300L and 9300LM can mix only at the same license level, so an Advantage stack requires matching licenses.
C9300LM-48T-4Y-A supports RIP, OSPF, EIGRP, BGP, IS-IS, PBR, VRRP, and HSRP under Network Advantage. IPv4 capacity totals 32000 routes, comprising 24000 direct and 8000 indirect entries. Those hardware totals are separate from the OSPF limit of 1000 routes applied to Network Essentials, the lower network license tier.
Yes, C9300LM-48T-4Y-A supports a second internal supply, but the standard hardware configuration includes one PWR-C6-600WAC. A second PWR-C6-600WAC is an ordering option rather than included redundancy. 101.4W is the measured full-port traffic consumption at 115V AC, not the power supply’s capacity.
The Catalyst 9300LM data model has four fixed 25G SFP28 uplinks, not a removable uplink-card bay. Uplink media must match the required link speed and far-end connection. Specify compatible transceivers or direct-attach media separately rather than treating an uplink network module as an installed component.
C9300LM-48U-4Y-A delivers Cisco UPOE on its 48 Gigabit copper ports, whereas C9300LM-48T-4Y-A carries data-only copper ports. Endpoint power is the relevant hardware difference for this comparison. Select the data model for independently powered equipment and the UPOE model when endpoints need power supplied over their access connections.
Network Advantage on C9300LM-48T-4Y-A adds BGP, full EIGRP, and IS-IS where C9300LM-48T-4Y-E supplies Network Essentials. Essentials includes routed access with OSPF capped at 1000 routes. The Advantage model suits advanced routing requirements; the Essentials version suits deployments confined to the smaller perpetual feature set.
C9300LM-48T-4Y-A provides four 25G SFP28 uplinks, while C9300L-48T-4X-A provides four 10G SFP+ uplinks. Compare the distribution-side link requirement before selecting either PID. The 25G model suits an aggregation connection specified at that speed; the 10G version suits a distribution plan limited to 10G.
The Catalyst 9300LM data model is a rack-mount 1U switch, not a desktop switch despite its mini designation. The chassis measures 43 mm high, 444 mm wide, and 275 mm deep, with a weight of 4.99 kg. Confirm cabinet clearance and mounting requirements before specifying the rack installation.
