WS-C3650-12X48UZ-S combines 12 multigigabit copper downlinks with 36 Gigabit Ethernet downlinks in a 48-port Layer 3 enterprise access switch. The multigigabit ports negotiate 100Mbps, 1Gbps, 2.5Gbps, 5Gbps or 10Gbps for mixed-speed access points and wired endpoints. Two fixed 40Gbps QSFP+ uplinks connect the access edge to the upstream network without a removable uplink card. Cisco UPOE extends endpoint power delivery beyond standard PoE+, while the installed IP Base feature set enables enterprise routed access. The 1U rack-mount chassis belongs to the Cisco Catalyst 3650 Series. The discontinued WS-C3650-12X48FD-S sibling provides PoE+ instead of UPOE, making endpoint power requirements the distinction between these variants rather than simply their copper port density.
WS-C3650-12X48UZ-S price for new stock is $5,775.00, a 80.6% saving from the Cisco list price of $29,704.00. WS-C3650-12X48UZ-S refurb price is $1,438.50. WS-C3650-12X48UZ-S is in stock and available for next-day dispatch. (terms applied)

472 Gbps switching capacity handles forwarding across the installed interfaces, and 351.19 Mpps forwarding rate supports packet processing at the access edge. 660W of shared PoE budget limits aggregate endpoint allocation with the standard PWR-C1-1100WAC supply. Static routing, RIPv1, RIPv2, RIPng and EIGRP Stub support local routing, while OSPF is restricted to routed access. Full EIGRP, BGPv4 and IS-ISv4 are not enabled by the shipped license. WS-C3650-12X48UZ-S uses 4 GB of DRAM and 4 GB of flash for Cisco IOS XE operation and image storage. The UADP ASIC supports 32000 MAC entries and an IPv4 resource total of 24000 entries covering ARP plus learned routes. A second internal power-supply bay provides an optional redundancy path, and three FAN-T1 fans cool the chassis. Administration includes the web UI, console CLI, SSH, Telnet and Cisco Prime Infrastructure. 184W at full test traffic excludes endpoint PoE loading, so facility power sizing must not treat that figure as fully loaded input demand.
Order WS-C3650-12X48UZ-S in new sealed or certified refurbished condition, and state the condition and required accessories on the purchase order. Certified refurbished units are inspected and bench-tested, with PoE output verified under load on every powered port, optics bay recognition checked, firmware verified and configuration wiped to factory default. ORM provides up to 3-year extended warranty on new units and up to 1 year on certified refurbished units; 30-day returns apply to every condition, terms apply, while Cisco's original-customer Enhanced Limited Lifetime Warranty is bounded by October 31, 2026. Enterprise and volume orders can use accepted POs, Net-30 for government and RMA with advance replacement, with regional stock/RMA coverage in the UK, EU, US and MEA.

Scenario: A large university deploys 2,000+ Wi-Fi 6 access points to serve 15,000 simultaneous users across lecture halls, dormitories and common areas. The WS-C3650-12X48UZ-S delivers 48 multigigabit PoE++ ports to power next-gen APs and dual 40 Gbps uplinks for zero-bottleneck aggregation into the campus core. Benefit/Outcome: Seamlessly scales to ultra-high wireless density, simplifies power provisioning, and guarantees predictable throughput—boosting end-user experience while reducing CAPEX on midspan injectors and spines.
Scenario: A mid-sized enterprise consolidates 200+ virtual machines on blade and rack servers requiring low-latency, lossless connectivity. The Catalyst 3650 48-port MGig switch provides 48×10 Gbps server links with fallback to 5 GbE/2.5 GbE and two 40 Gbps uplinks into the spine layer. Benefit/Outcome: Delivers sub-microsecond latency, dynamic link-speed negotiation, and advanced IP-Base routing for overlay networks—maximizing VM performance, improving east-west bandwidth utilization, and accelerating application delivery.
Scenario: A distributed retail chain requires converged voice, video surveillance and POS data at 150 branch sites. The WS-C3650-12X48UZ-S handles 48 PoE ports for IP phones and cameras, supports Cisco TrustSec segmentation, and enforces real-time QoS policies. Benefit/Outcome: Centralizes security enforcement and traffic prioritization at the edge, streamlines remote management via Cisco DNA Center, and ensures uninterrupted operations—driving compliance, reducing onsite support costs, and improving customer satisfaction.
When endpoint power drives the purchase, simultaneous 60W delivery is limited to 29 ports even with two PWR-C1-1100WAC power supplies. Include the second PWR-C1-1100WAC when that loading is required. Record each endpoint's requested power and aggregate allocation before specifying the supply configuration on the purchase order.
When a refresh includes inter-VLAN segmentation, the hardware supports 1000 switched virtual interfaces and 4094 VLAN IDs. That scale does not expand the routing features enabled by the purchased network license. List the intended virtual interfaces and required routing functions, then validate the software entitlement before issuing the purchase order.
When a staging environment needs traffic-flow visibility before deployment, the 48-port hardware supports 48000 Flexible NetFlow entries. Collection and analysis require a management workflow beyond physical port checks. Define the flows to be observed and verify the collector configuration before specifying the test unit and its required connections on the purchase order.
Full BGP or IS-IS routing
IP Base excludes BGPv4 and IS-ISv4; those features require IP Services. For a current hardware migration, specify C9300L-48UXG-2Q-A and validate the required routing entitlement.
60W power on every downlink
Two PWR-C1-1100WAC power supplies support 60W delivery on a maximum of 29 ports. The power system cannot supply 48 simultaneous endpoints at that per-port load.
Integrated wireless control on newer software
Converged Access is unsupported after Cisco IOS XE Denali 16.3.x, so integrated wireless-controller operation cannot be assumed on 16.12.x. IP Base alone does not restore that removed capability.

WS-C3650-12X48UZ-S identifies a Catalyst 3650 with 12 multigigabit ports among 48 copper downlinks, Cisco UPOE, two 40Gbps uplinks and IP Base. WS-C3650 identifies the family; 12X and 48 identify the port arrangement; U and Z identify power and uplinks; S selects IP Base.
The Catalyst 3650 supports a web UI, console CLI, remote CLI over SSH or Telnet, Cisco Prime Infrastructure and NETCONF-YANG over SSH. SNMPv3 provides a monitoring path. SSH and cryptographic SNMPv3 require the cryptographic software image, so confirm the image and management configuration before deployment.
WS-C3650-12X48UZ-S provides 660W of shared PoE budget with its standard PWR-C1-1100WAC supply, and Cisco UPOE supports 60W per port. The shared budget does not power every downlink at maximum output. Two PWR-C1-1100WAC supplies enable 60W delivery on a maximum of 29 ports; record aggregate endpoint demand before ordering.
WS-C3650-12X48UZ-S has two fixed 40Gbps QSFP+ uplinks rather than an empty network-module bay. The native uplink configuration is independent of the multigigabit copper downlinks. Specify compatible uplink optics or cabling for the upstream connection and confirm those items are included in the purchase order.
StackWise-160 connects nine Catalyst 3650 members with 160 Gbps stack bandwidth. Members must share the network license level and belong to the same family. C3650-STACK-KIT= provides the stack module; STACK-T2-50CM=, STACK-T2-1M= and STACK-T2-3M= are stacking cable options. Confirm adapter presence and cable lengths before ordering another member.
WS-C3650-12X48UZ-S supports Static routing, RIPv1, RIPv2, RIPng, EIGRP Stub and OSPF for routed access under IP Base. Full EIGRP, BGPv4 and IS-ISv4 require IP Services and are not enabled by this PID's shipped license. The 24000-entry IPv4 total includes ARP and learned routes, not an unrestricted protocol-specific entitlement.
WS-C3650-12X48UZ-S ships with permanent IP Base, not a mandatory term subscription. Optional Cisco DNA Essentials or Cisco DNA Advantage subscriptions start at three years, with availability dependent on software release. Cisco IOS XE 16.9.1 onward requires Smart Licensing and a Smart Account; earlier releases use RTU. An IP Services upgrade is a separate entitlement.
Yes, WS-C3650-12X48UZ-S reached end of sale on October 31, 2021, and its last date of support is October 31, 2026. C9300L-48UXG-2Q-A is its current successor. New service attachments ended October 31, 2022, and renewals ended January 29, 2026, so remaining Cisco coverage depends on an existing eligible entitlement.
ORM offers WS-C3650-12X48UZ-S new sealed with up to 3-year extended warranty or certified refurbished with up to 1 year of warranty. Both conditions carry 30-day returns, terms apply. Cisco's Enhanced Limited Lifetime Warranty covers the original customer, not automatic resale entitlement, and Cisco support ends October 31, 2026. Refurbished units are inspected and bench-tested.
Yes, WS-C3650-12X48UZ-S accepts a second internal power supply, but ships with one PWR-C1-1100WAC rather than two supplies as standard. The second bay is an optional redundancy path. Specify a compatible PWR-C1-1100WAC for the additional position and confirm the supply quantity on the purchase order.
WS-C3650-12X48UZ-S supports 60W-per-port Cisco UPOE, whereas WS-C3650-12X48FD-S provides 30W-per-port PoE+. Both are discontinued Catalyst 3650 models. The UPOE version matches higher-draw endpoint requirements; the PoE+ version matches installed environments whose endpoints need no more than 30W per port, subject to each switch's shared power budget.
WS-C3650-12X48UZ-S ships with IP Base, whereas WS-C3650-12X48UZ-E ships with IP Services. IP Base includes EIGRP Stub and routed-access OSPF; IP Services adds full EIGRP, BGPv4 and IS-ISv4. Both models are discontinued. The IP Base version matches basic routed access; the IP Services version matches existing 3650 deployments requiring advanced routing.
C9300L-48UXG-2Q-A uses StackWise-320 with 320 Gbps stack bandwidth, whereas WS-C3650-12X48UZ-S uses StackWise-160 with 160 Gbps. The Catalyst 9300L model is the current successor; the Catalyst 3650 model is discontinued. The 3650 matches existing stack compatibility requirements, while the 9300L suits a new stack architecture and forward migration.
