C9300LM-48U-4Y-A combines a shallow-depth chassis with 48 Gigabit Ethernet copper access ports and four fixed 25G SFP28 uplinks. This managed Layer 3 enterprise access switch supplies Cisco UPOE to powered endpoints and occupies one rack unit. The Cisco Catalyst 9300LM uses an integrated uplink architecture rather than an empty network-module bay, so uplink expansion does not involve installing a removable card. Network Advantage is the included perpetual network license, providing advanced routing and segmentation beyond the entry network tier. The configuration brings powered copper connections and higher-speed fiber uplinks together within the mini chassis. Its closest non-powered sibling, C9300LM-48T-4Y-A, retains 48 Gigabit copper access ports and four 25G uplinks but provides data-only access connections instead of UPOE.
C9300LM-48U-4Y-A price for new stock is $12,594.75. C9300LM-48U-4Y-A refurb price is $9,005.85. C9300LM-48U-4Y-A is in stock and available for next-day dispatch. (terms applied)

296 Gbps switching capacity covers standalone operation, while 220.22 Mpps forwarding provides the packet-processing figure for traffic sizing. 790W of shared PoE power requires endpoint allocations to remain within the available budget rather than treating every powered port as an independent maximum. OSPF, EIGRP, BGP and IS-IS support dynamic routed-access configurations under the installed network tier; PIM-SM and PIM-BIDIR provide multicast routing options. The IPv4 forwarding resources accommodate 32000 total entries, comprising 24000 direct and 8000 indirect routes. C9300LM-48U-4Y-A carries 8 GB of DRAM and 16 GB of flash for system operation and local software storage. A 16 MB packet buffer handles queued traffic, while the MAC table accommodates 32000 entries. Within the Catalyst 9000 family, configuration and automation options include CLI, WebUI, NETCONF and RESTCONF. Model-driven telemetry provides operational visibility. StackPower is not supported, so data stacking does not create a shared power pool between chassis.
ORM Systems supplies C9300LM-48U-4Y-A in new sealed and certified refurbished condition, with purchase orders accepted for either option. Certified refurbished units are inspected and bench-tested for power-on and POST, clean boot, rated-speed links on every port and PoE output under load on every powered port. New units carry up to a 3-year extended warranty; certified refurbished units carry up to 1 year, and every condition includes 30-day returns; terms apply. Specify the condition and quantity on the PO for enterprise or volume purchasing; Net-30 is available for government, with RMA advance replacement and regional stock/RMA across the UK, EU, US and MEA.

When replacing discontinued WS-C3650-48FQM-S, WS-C3650-48FQM-E or C1-WS3650-48FQM/K9 equipment, C9300LM-48U-4Y-A is the replacement for all three variants. The older models reached end of sale on May 31, 2023, and last support is May 31, 2028. Confirm the replacement license and stacking accessories before issuing the purchase order.
When application staging requires an external SSD-240G storage device, the Catalyst 9300LM needs 9300LM-SSD-ACCKIT= for installation. The mounting accessory belongs on a separate purchase-order line rather than being assumed present with the chassis. Identify whether an existing kit is available and include the required storage and mounting components before ordering.
When a multisite purchase must enter a shared license inventory, a Smart Account is mandatory for the Cisco order. Account assignment belongs with the hardware and subscription configuration rather than being deferred until installation. Confirm the receiving account and selected subscription term for every site before issuing the purchase order.
Multigigabit speeds on copper access ports
C9300LM-48U-4Y-A limits copper access connections to 1Gbps. C9300LM-48UX-4Y-A provides eight Multigigabit copper ports reaching 10Gbps plus 40 Gigabit ports in the same mini chassis family.
90W power for individual endpoints
C9300LM-48U-4Y-A provides 60W Cisco UPOE per port, not 90W UPOE+. C9300X-48HX-A supports 90W UPOE+ per port but uses a deeper chassis with modular uplinks.

C9300LM-48U-4Y-A identifies a Catalyst 9300 mini switch with 48 Gigabit copper UPOE ports, four 25G uplinks and Network Advantage. C9300LM identifies the mini family, 48 is the access-port count, U denotes UPOE, 4Y identifies four 25G uplinks, and A identifies the included Network Advantage license.
C9300LM-48U-4Y-A supports Cisco IOS XE CLI, local console or SSH access, embedded WebUI, Cisco Catalyst Center and Meraki dashboard management with IOS XE. WebUI is included with the default image. Controller and dashboard functions depend on the selected software release and licensing; NETCONF and RESTCONF provide programmable configuration interfaces.
Cisco has not announced an end-of-sale date for Catalyst 9300LM. C9300LM-48U-4Y-A therefore has no hardware end-of-sale milestone to use as a procurement cutoff. Software release lifecycles and separately purchased accessories remain distinct from the switch hardware lifecycle and should not be treated as chassis retirement dates.
ORM Systems offers C9300LM-48U-4Y-A new sealed or certified refurbished: new units have up to a 3-year extended warranty; certified refurbished units have up to 1 year. Cisco's platform warranty is Enhanced Limited Lifetime. Every condition has 30-day returns; terms apply.
C9300LM-48U-4Y-A includes perpetual Network Advantage; new orders require an accompanying subscription. Cisco DNA Essentials/Advantage and Cisco Catalyst Essentials/Advantage start at three years, with the subscription tier matching the network tier. Cisco Networking Subscription offers Cisco Switching Essentials or Cisco Switching Advantage with a 36-month minimum. Expiring add-ons do not remove the perpetual network license.
C9300LM-48U-4Y-A replaces the discontinued WS-C3650-48FQM-S, WS-C3650-48FQM-E and C1-WS3650-48FQM/K9. Those Catalyst 3650 Mini models reached end of sale on May 31, 2023, with last support on May 31, 2028. Replacement planning should specify the new network license and compatible stacking hardware rather than reuse predecessor accessories.
C9300LM-48U-4Y-A provides a shared 790W PoE budget with its default PWR-C6-1KWAC supply, increasing to 1790W with two PWR-C6-1KWAC supplies. Individual Cisco UPOE ports support 60W. The chassis budget does not permit every access port to deliver that maximum simultaneously, so endpoint power requests require allocation.
The 48-port Gigabit UPOE configuration on C9300LM-48U-4Y-A includes four fixed 25G SFP28 uplink ports. These connections are built into the chassis rather than supplied by an optional network module. Specify compatible transceivers for the intended fiber medium, link distance and connection to the upstream equipment.
Catalyst 9300LM StackWise-320 stacks eight members at 320 Gbps stacking bandwidth. C9300L-STACK-KIT2 supplies the required adapters and default STACK-T3A-50CM cable; STACK-T3A-1M and STACK-T3A-3M provide longer connections. Supported partners are Catalyst 9300L and Catalyst 9300LM models with matching network license levels, not modular-uplink Catalyst 9300 models.
Yes, C9300LM-48U-4Y-A supports full OSPF, EIGRP, BGP and IS-IS through Network Advantage, alongside IPv6 routing and multicast capabilities. The IPv4 forwarding total is 32000 entries, comprising 24000 direct and 8000 indirect routes. The 1000-route OSPF restriction associated with Network Essentials is not the Network Advantage routing limit.
C9300LM-48U-4Y-A ships with one PWR-C6-1KWAC AC power supply, while the second internal supply position is optional. A second PWR-C6-1KWAC can increase the available endpoint-power budget. Specify the additional supply explicitly when the purchase requires two installed supplies rather than assuming redundancy is included in the base chassis.
C9300LM-48U-4Y-A powers endpoints through Cisco UPOE, whereas C9300LM-48T-4Y-A provides data-only copper access ports without PoE. Both configurations retain 48 Gigabit access ports, four fixed 25G uplinks and Network Advantage. Choose the U variant for powered endpoints and the T variant when access devices use separate power.
C9300LM-48U-4Y-A includes Network Advantage, while C9300LM-48U-4Y-E includes Network Essentials. The A configuration enables advanced routing capabilities such as full OSPF, EIGRP, BGP and IS-IS; Essentials carries routed-access restrictions. Buyers requiring advanced routing should specify A, while buyers working within Essentials capabilities can select E.
C9300LM-48U-4Y-A provides 48 Gigabit UPOE access ports, whereas C9300LM-24U-4Y-A provides 24. Both retain four fixed 25G uplinks and Network Advantage. The 48-port configuration addresses a larger endpoint count within one chassis; the 24-port configuration serves installations whose connection schedule fits the smaller access-port count.
