WS-C3750X-24U-E is a stackable Layer 3 enterprise access switch with 24 fixed 10/100/1000 RJ-45 ports and Cisco UPOE capability for compatible endpoints drawing 60W per port. The 1U rack chassis belongs to the Cisco Catalyst 3750-X series and carries the IP Services feature set for advanced IPv4 and IPv6 routing. Uplink connectivity comes from an optional network module rather than built-in uplink ports; the base configuration leaves that bay empty. Available module architectures include Gigabit SFP, 10G SFP+, and 10GBASE-T. The discontinued WS-C3750X-24P-E sibling provides PoE+ rather than UPOE, distinguishing purchases for conventional powered endpoints from those requiring higher per-port power. Endpoint demand must still fit the installed power allocation.

160 Gbps switching capacity defines the switching fabric. 65.5 Mpps forwarding applies to the configuration with two 10GbE uplinks, so that figure assumes an installed uplink module. 800W of shared PoE power is available with the standard supply; allocation across powered endpoints determines how much each port can deliver concurrently. OSPF, EIGRP, BGPv4, and IS-ISv4 provide advanced unicast routing under IP Services, while OSPFv3 and EIGRPv6 support IPv6 routing. PIM-SM and PIM-DM handle multicast routing. WS-C3750X-24U-E contains 256 MB of DRAM and 64 MB of flash for Cisco IOS operation and image storage. Switching Database Manager templates change resource allocation: the routing template supports 11000 unicast routes, while the VLAN template supports 12000 MAC entries. These are different configurations, not simultaneous maxima. Eight egress queues per port separate traffic classes, with four user-configurable queues and four reserved for system use. MACsec supplies hardware-based encryption on host-facing links.
WS-C3750X-24U-E is available new sealed with an ORM warranty of up to a 3-year extended term, or certified refurbished with up to 1 year; Cisco's enhanced limited lifetime hardware warranty ended October 31, 2021. Certified refurbished units are inspected and bench-tested, with PoE output verified under load on every powered port, firmware verified, and configurations wiped to factory default. Specify condition, quantity, and accessories on the PO; every condition includes 30-day returns, terms apply. ORM Systems accepts POs, offers Net-30 for government and RMA with advance replacement, and supports enterprise and volume orders through regional stock/RMA coverage in the UK, EU, US, and MEA.

In a multi-building enterprise campus network, the WS-C3750X-24U-E Catalyst 3750X 24-Port UPOE IP Services switch serves as the aggregation layer. By stacking up to nine switches via StackWise Plus, IT teams achieve sub-50ms failover and scale to 216 ports under a single management IP. The 24 UPOE ports deliver up to 60W per port to power wireless access points and PoE cameras. Benefit: Simplified operations with centralized PoE control, industry-leading resiliency, and 30% reduction in rack footprint and cabling complexity.
In a smart workplace deployment, the Catalyst 3750X 24-Port UPOE IP Services switch powers and manages diverse IoT endpoints—environmental sensors, digital signage, and 802.11ac Wave 2 APs—over a single fiber uplink. Intelligent PoE budget allocation and Cisco EnergyWise deliver energy-aware port control. Benefit: Streamlined installation with consolidated power and data, real-time energy monitoring, and a 25% cut in operational costs through dynamic PoE scaling.
For high-volume call centers and executive office floors, the WS-C3750X-24U-E provides 24 UPOE ports to power Cisco IP phones and HD video endpoints while enforcing strict QoS policies. Integrated Cisco TrustSec segmentation and IEEE 802.1X authentication protect voice VLANs. Benefit: Guaranteed voice and video quality with end-to-end encryption, 99.99% uptime via redundant power supplies, and 40% fewer help-desk trouble tickets due to automated security posture enforcement.
When extending an existing installation that shares power between chassis, distinguish the power connections from the data-stack connections. Cisco StackPower groups four switches and uses CAB-SPWR-30CM= or CAB-SPWR-150CM= cables rather than data-stacking cables. Specify cable reach, the power-sharing or redundancy mode, and the installed supply inventory before the PO.
When retaining an access configuration that uses policy-based forwarding or separate routing contexts, IP Services supplies PBR and VRF-Lite rather than requiring an external routing function for those features. HSRP supports 32 links per unit or stack. Check the existing routing contexts, policies, and gateway count before specifying the replacement unit.
When staging a unit for an established administrative environment, SSH and cryptographic SNMPv3 require the special cryptographic software image. USB Type-B provides a console connection for initial access, while USB Type-A supports storage. Specify the required image and console connection, then verify administrative access during staging before approving the deployment order.
Active Cisco hardware support coverage
WS-C3750X-24U-E reached its last date of Cisco hardware support on October 31, 2021. C9300-24U-A is the current successor through the discontinued WS-C3850-24U-E.
Native multigigabit connections for endpoints
WS-C3750X-24U-E has 24 fixed access ports limited to 1GbE. C3KX-NM-10GT adds 10GbE uplinks but does not increase the speed of those endpoint-facing ports.
More than 60W per powered endpoint
WS-C3750X-24U-E delivers a maximum of 60W through each UPOE-capable port. Adding another C3KX-PWR-1100WAC increases the shared power budget, not the individual port limit.

WS-C3750X-24U-E identifies a Catalyst 3750-X stackable switch: WS-C3750X identifies the series, 24 denotes the access-port count, U denotes UPOE, and E denotes IP Services. The configuration includes Gigabit Ethernet access ports and a C3KX-PWR-1100WAC supply; the part number does not include an installed uplink module.
WS-C3750X-24U-E supports CLI management through console connections, Telnet, or SSH, plus SNMP, PC-based configuration tools, and CiscoWorks LMS. USB Type-B provides console access, and an Ethernet management port supports out-of-band connectivity. SSH and cryptographic SNMPv3 require the special cryptographic software image rather than merely an IP Services license.
Yes, WS-C3750X-24U-E ended sale on October 30, 2016, and Cisco hardware support ended on October 31, 2021. The direct successor WS-C3850-24U-E is also discontinued. Its successor is C9300-24U-A, the current replacement in this migration chain; remaining WS-C3750X-24U-E purchases are legacy hardware purchases rather than Cisco-supported hardware deployments.
ORM Systems offers WS-C3750X-24U-E new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Both conditions have 30-day returns, terms apply. Cisco's original enhanced limited lifetime hardware warranty ended October 31, 2021; Cisco hardware service has also ended.
WS-C3750X-24U-E carries the IP Services feature set, including advanced IPv4 and IPv6 routing beyond the IP Base tier. Cisco IOS activates functionality from the license file present at startup. Verify that entitlement accompanies the purchase, particularly when ordering a previously used unit; installed firmware and licensed functionality are separate checks.
WS-C3750X-24U-E provides an 800W shared PoE budget with its standard C3KX-PWR-1100WAC and supports 60W per UPOE port. Two C3KX-PWR-1100WAC supplies provide an 1800W budget. All 24 ports at 60W require 1440W, so the standard single-supply configuration cannot deliver maximum UPOE power to every port simultaneously.
Catalyst 3750-X accepts C3KX-NM-1G for four Gigabit SFP uplinks, C3KX-NM-10G for two 10G SFP+ uplinks, C3KX-NM-10GT for two 10GBASE-T uplinks, and C3KX-SM-10G for two 10G SFP+ uplinks with additional services. The base switch excludes the uplink module; fiber configurations also require compatible optics for the selected module.
Catalyst 3750-X StackWise Plus stacks nine members and provides a 64 Gbps stack interconnect. Data-stack cable options are CAB-STACK-50CM=, CAB-STACK-1M=, and CAB-STACK-3M=. LAN Base members cannot mix with IP Base or IP Services members. Cisco StackPower is separate and groups four switches using different power-sharing cables.
WS-C3750X-24U-E supports 60W UPOE per port, whereas WS-C3750X-24P-E supports 30W PoE+ per port. Both retain 24 Gigabit access ports and IP Services, and both are discontinued. The UPOE model suits compatible higher-draw endpoints; the PoE+ model suits endpoints whose requirements remain within the lower per-port power limit.
WS-C3750X-24U-E includes IP Services, while WS-C3750X-24U-S includes IP Base on the same 24-port UPOE hardware configuration. IP Services supplies full OSPF, EIGRP, BGPv4, and IS-ISv4 rather than the more limited IP Base routing feature set. Both are discontinued; select the E variant when those advanced routing functions are required.
WS-C3750X-24U-E has ended Cisco hardware support, whereas C9300-24U-A is the current 24-port UPOE successor reached through the discontinued WS-C3850-24U-E. The older model suits maintaining a legacy installation with reseller-backed hardware arrangements. C9300-24U-A suits buyers replacing that installation with the current generation rather than extending the discontinued hardware estate.
No, WS-C3750X-24U-E ships with one C3KX-PWR-1100WAC, and the second power-supply bay is available for an optional additional supply. Order another C3KX-PWR-1100WAC when the configuration requires that combination. Size powered-endpoint demand against the supply capacity remaining after a failure rather than assuming dual supplies preserve every possible PoE allocation.
137.21W is the WS-C3750X-24U-E measurement at full test traffic with C3KX-SM-10G installed and no PoE load, not a powered-endpoint maximum. Include endpoint demand when sizing electrical circuits and UPS capacity. The C3KX-PWR-1100WAC rating describes power-supply capacity rather than measured consumption by the switch under that test configuration.
