WS-C3650-12X48UZ-E combines twelve multigigabit downlinks with thirty-six Gigabit Ethernet downlinks in a 48-port Layer 3 enterprise access switch. The multigigabit connections negotiate 100 Mbps, 1 Gbps, 2.5 Gbps, 5 Gbps or 10 Gbps, allowing endpoint connections to use different speeds within the same chassis. Cisco UPOE supports endpoint power delivery of 60W per port, subject to the shared power allocation. Two fixed 40G QSFP+ uplinks connect the access switch to distribution without a removable uplink card. The Catalyst 3650 occupies one rack unit and carries the IP Services feature set for advanced enterprise routing. The discontinued WS-C3650-12X48FD-E sibling instead provides PoE+ at 30W per port. Assign higher-speed endpoint connections to the multigigabit downlinks when preparing the port schedule.
WS-C3650-12X48UZ-E price for new stock is $5,775.00, a 84% saving from the Cisco list price of $35,992.00. WS-C3650-12X48UZ-E refurb price is $1,732.50. WS-C3650-12X48UZ-E is in stock and available for free next-day delivery. (terms applied)

472 Gbps switching capacity provides the switching fabric rating for this configuration, while 351.19 Mpps forwarding supports packet-rate sizing. 660W of shared PoE power determines the endpoint allocation available with the default supply. OSPF, EIGRP, BGPv4 and IS-ISv4 provide dynamic IPv4 routing; OSPFv3 and EIGRPv6 extend routing to IPv6, while PIM-SM and PIM-DM support multicast routing. WS-C3650-12X48UZ-E pairs 4 GB DRAM with 4 GB flash for its Cisco IOS XE software environment. Cisco UADP handles forwarding, with a 32000-entry MAC table and a 24000-entry IPv4 route total that includes ARP plus learned routes. The Cisco Catalyst 3650 Series also supports Flexible NetFlow for traffic monitoring. Three modular fans provide chassis cooling. 184W consumption at full test traffic excludes endpoint PoE loading and must not be treated as loaded-system draw. A second internal power supply is optional rather than included.

In a large enterprise campus with thousands of Wi-Fi and IoT endpoints, the WS-C3650-12X48UZ-E delivers 48-port multigigabit PoE, Layer 3 IP Services and 2×40 Gb uplinks in a single chassis. By consolidating wired, wireless and IoT traffic on a unified Catalyst 3650 platform with advanced QoS and SSO stacking, IT teams reduce switch sprawl, simplify management and ensure deterministic performance. Outcome: 40 % faster on-boarding of new devices, 30 % lower power footprint and seamless policy enforcement across the access layer.
An education district needed to aggregate multiple access switches into a resilient backbone without forklift upgrades. Deploying the WS-C3650-12X48UZ-E with dual 40 Gb uplinks and Cisco StackWise-320 stacking, network engineers achieved up to 320 Gbps aggregate throughput and sub-second failover. Built-in IP Services deliver dynamic routing, multicast optimization and segment-routing capabilities. Outcome: scalable distribution plane supporting 20 % annual user growth, 99.999 % uptime and simplified operations via a single management image.
A healthcare facility required strict segmentation between medical devices, guest BYOD and administrative traffic. The Catalyst 3650 48-port mGig switch leverages comprehensive IP Services for IPv6, VRF, Cisco TrustSec and integrated ACLs to isolate workloads at wire-speed. Its PoE+ ports power IP phones, cameras and badge readers while 2×40 Gb uplinks ensure zero-contention backhaul. Outcome: regulatory compliance with HIPAA segmentation, 50 % reduction in security incidents and unified policy enforcement across wired and wireless domains.
When adding endpoints that require full Cisco UPOE output, the dual-supply configuration becomes an ordering decision rather than an assumed capability. Two PWR-C1-1100WAC supplies support full UPOE output on a maximum of 29 ports. List endpoint power requirements and specify the additional PWR-C1-1100WAC= supply before issuing the PO.
When expanding an existing switching stack, prepare the member configuration around the active and standby roles rather than treating each chassis as an independently managed switch. StackWise-160 presents one switching system with a single IP address. Check software versions, member configuration and the existing stack topology before ordering another chassis.
For lab validation before a production purchase, distinguish an unpowered-endpoint baseline from the final endpoint-loaded configuration. The zero-traffic consumption baseline is 162.4W without PoE loading, and cold starts require an ambient temperature of at least 0°C. Specify the staging environment and endpoint load to be checked before approving the hardware quantity.
Full UPOE output on every port
WS-C3650-12X48UZ-E supports full 60W UPOE output on a maximum of 29 ports with two PWR-C1-1100WAC supplies, not all 48 ports simultaneously.
Multigigabit speeds on every downlink
Only 12 WS-C3650-12X48UZ-E downlinks support multigigabit operation; the remaining 36 downlinks stop at Gigabit Ethernet. An all-multigigabit endpoint schedule exceeds this port configuration.
Cisco service beyond October 2026
Cisco service for WS-C3650-12X48UZ-E ends October 31, 2026. C9300L-48UXG-2Q-A is the replacement for buyers specifying a current migration model rather than discontinued hardware.

WS-C3650-12X48UZ-E identifies a Catalyst 3650 with IP Services: WS-C3650 is the family, 12X48UZ specifies 48 downlinks including 12 multigigabit ports and two 40G uplinks, and E selects IP Services. The full configuration also includes Cisco UPOE and one PWR-C1-1100WAC supply.
WS-C3650-12X48UZ-E supports CLI management through a console, Telnet or SSH, SNMP management, and Cisco Prime Infrastructure. SSH requires a cryptographic software image. Specify the management network, administrator access method and monitoring requirements when preparing the hardware order and staging configuration.
Yes, WS-C3650-12X48UZ-E reached end of sale on October 31, 2021, and its last date of Cisco support is October 31, 2026. C9300L-48UXG-2Q-A is its replacement. Remaining hardware purchases should distinguish reseller condition and coverage from any existing Cisco service entitlement.
ORM Systems offers WS-C3650-12X48UZ-E new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for refurbished units. Returns are 30 days on every condition, terms apply. Cisco Enhanced Limited Lifetime coverage concerns the original owner; Cisco service ends October 31, 2026.
WS-C3650-12X48UZ-E carries the IP Services feature set through RTU licensing. Historical optional Cisco DNA Advantage subscriptions used three-year or five-year terms, with three years the minimum; Cisco DNA Premier bundled Cisco DNA Advantage. Specify subscription entitlement separately rather than treating the hardware condition as proof of subscription coverage.
WS-C3650-12X48UZ-E provides a shared 660W PoE budget with its default supply and supports Cisco UPOE delivery of 60W per port. The per-port ceiling does not mean every port can draw that amount simultaneously. Prepare an endpoint power schedule before specifying the supply configuration on the purchase order.
The WS-C3650-12X48UZ-E Catalyst 3650 configuration uses two fixed 40G QSFP+ uplinks rather than a removable uplink module. The uplink architecture is selected with the chassis configuration. Confirm compatible QSFP+ connectivity, fiber requirements and link distances before specifying the uplink accessories on the purchase order.
Catalyst 3650 StackWise-160 stacks nine members with 160 Gbps stack bandwidth. C3650-STACK-KIT= supplies the optional stack hardware; cable choices are STACK-T2-50CM=, STACK-T2-1M= and STACK-T2-3M=. Match member license levels and check installed adapters before ordering additional chassis, stack hardware and the required cable lengths.
WS-C3650-12X48UZ-E supports full OSPF, EIGRP, BGPv4 and IS-ISv4 through IP Services, together with OSPFv3 and EIGRPv6 for IPv6. PIM-SM and PIM-DM support multicast routing. The 24000-entry IPv4 scale includes ARP plus learned routes, so route planning must account for both uses of that total.
No, WS-C3650-12X48UZ-E ships with one PWR-C1-1100WAC supply; the second internal supply is optional. A PWR-C1-1100WAC= spare can be specified for the additional position. Confirm the actual installed supply quantity when selecting condition and accessories rather than assuming both internal positions arrive populated.
WS-C3650-12X48UZ-E requires one rack unit and measures 44 mm high, 445 mm wide and 486 mm deep, with a shipping weight of 8.08 kg. Check cabinet depth, rear cable clearance and mounting arrangements before ordering; rack height alone does not establish that the chassis fits the cabinet.
WS-C3650-12X48UZ-E consumes 184W at full traffic in the no-PoE-load test, with a 162.4W zero-traffic baseline. These figures exclude power delivered to endpoints and are not a fully loaded system maximum. Electrical and cooling planning must distinguish chassis consumption from the selected endpoint load.
WS-C3650-12X48UZ-E supports Cisco UPOE at 60W per port, whereas WS-C3650-12X48FD-E supports PoE+ at 30W per port, subject to shared power budgets. Both models are discontinued. The UPOE model addresses legacy high-draw endpoint requirements; the PoE+ sibling addresses legacy deployments whose endpoints stay within the lower per-port ceiling.
WS-C3650-12X48UZ-E includes IP Services, while WS-C3650-12X48UZ-S includes IP Base. IP Services enables full OSPF, EIGRP, BGPv4 and IS-ISv4; IP Base provides the lower feature tier. Both models are discontinued. Choose the E model for advanced legacy routing requirements and the S model when the existing design requires IP Base.
WS-C3650-12X48UZ-E is discontinued with Cisco support ending October 31, 2026; C9300L-48UXG-2Q-A is its replacement. The migration configuration retains 48 ports, twelve multigigabit connections and two 40G uplinks. The older model suits exact-hardware legacy requirements, while the replacement addresses buyers specifying the migration configuration for a refresh.
