WS-C3750X-24S-E is a Layer 3 fiber access switch with 24 fixed Gigabit SFP ports and a vacant uplink bay in a 1U rack-mount chassis. The Catalyst 3750-X configuration carries IP Services and provides no PoE output, separating fiber access connectivity from powered copper endpoint connections. Uplink choices include C3KX-NM-1G for Gigabit connections, C3KX-NM-10G for 10G SFP+ connections and C3KX-NM-10GT for copper 10G connections; no uplink card is installed by default. The discontinued WS-C3750X-24S-S carries IP Base instead of IP Services. For an existing enterprise fiber network, the purchasing distinction is the combination of fixed access interfaces, separately selected uplink hardware and the advanced routing feature set.
WS-C3750X-24S-E price for new stock is $3,969.00, a 88.5% saving from the Cisco list price of $34,500.00. WS-C3750X-24S-E refurb price is $665.70. WS-C3750X-24S-E is in stock and available for next-day dispatch. (terms applied)

160 Gbps switching fabric carries traffic through the switch hardware. 65.5 Mpps forwarding is rated with two 10GbE uplinks, rather than an empty uplink bay. OSPF, EIGRP, BGPv4 and IS-ISv4 support advanced unicast routing, while OSPFv3 and EIGRPv6 extend routing to IPv6. WS-C3750X-24S-E uses 512 MB DRAM and 128 MB flash for Cisco IOS operation and image storage. Resource allocation depends on the selected template: the routing template accommodates 11000 total unicast routes, split between 3000 directly connected hosts and 8000 indirect routes. The VLAN template instead accommodates 12000 MAC addresses and allocates no unicast routes, so those maxima are not simultaneous. 156.8W consumption at full traffic with C3KX-SM-10G provides a configuration-specific power-planning reference, not the rating of the shipped C3KX-PWR-350WAC. Console administration, SSH, Telnet and SNMP provide local and network management paths; cryptographic management requires the appropriate software image.
ORM Systems offers WS-C3750X-24S-E new sealed with up to 3-year extended ORM warranty or certified refurbished with up to 1-year ORM warranty; every condition has 30-day returns, with terms applying. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, optics bay recognition, PSU status and fan status; firmware is verified and the configuration is wiped to factory default. Specify condition, quantity and the required configuration before issuing the PO; Cisco's enhanced limited lifetime hardware warranty and Cisco service ended October 31, 2021. For enterprise and volume orders, POs are accepted and Net-30 is available for government buyers.

In medium to large enterprise campuses, the WS-C3750X-24S-E-TAA CAT3750-X 24PORT GBE SFP IP SVCS functions as a core aggregation switch using 24 1Gb SFP uplinks and StackWise Plus stacking up to 480 Gbps. Leveraging Cisco IP Services for advanced routing (OSPF/EIGRP), QoS enforcement and rapid failover, it delivers streamlined topology, sub-millisecond convergence and 99.99% uptime. Outcome: deterministic performance, simplified management and enterprise-grade availability.
In remote branches or retail outlets, the WS-C3750X-24S-E-TAA CAT3750-X 24PORT GBE SFP IP SVCS aggregates access switches handling IP telephony and Wi-Fi APs via 1 Gb fiber links to the WAN edge. With Cisco IP Services, it enforces end-to-end QoS, dynamic routing (EIGRP/OSPF) and secure VLAN segmentation. Outcome: prioritized voice and wireless traffic, consistent SLA compliance and reduced branch infrastructure complexity.
In hotels and healthcare facilities, the WS-C3750X-24S-E-TAA CAT3750-X 24PORT GBE SFP IP SVCS with IP Services and VRF-Lite enables secure multi-tenant segmentation over a single physical fabric. Its 24 fiber uplinks isolate guest, staff and IoT traffic, while granular ACLs and route-leak controls enforce compliance. Outcome: 40% hardware reduction, robust traffic isolation and simplified policy management.
When routed fiber access must carry separate networks with overlapping IP addresses, VRF-Lite provides distinct routing contexts. Keep each network's addressing and forwarding requirements separate during configuration planning rather than treating isolation as a cabling decision. Specify the required routing contexts and configuration acceptance checks before issuing the PO.
When a legacy hardware purchase must pass staging before installation, Generic Online Diagnostics and Onboard Failure Logging provide onboard diagnostic and failure-history tools. Define which diagnostic results will be reviewed alongside the receiving inspection, rather than relying only on a successful boot. Specify those acceptance checks before the PO.
When a spare purchase must cover installations in multiple regions, ORM supports regional stock and RMA across the UK, EU, US and MEA. RMA with advance replacement is available. Identify the receiving region, spare quantity and required condition so the purchase order states the intended supply and replacement arrangement.
PoE power for copper endpoints
WS-C3750X-24S-E has no powered access ports. Its SFP interfaces provide network connectivity rather than endpoint power, so the chassis cannot supply PoE to attached phones or access points.
10G speeds on every access port
WS-C3750X-24S-E has fixed Gigabit SFP access interfaces. Optional 10G uplink hardware does not change those access-port speeds, so a removable uplink card cannot satisfy a 10G access requirement.
Active Cisco hardware service coverage
Cisco service for WS-C3750X-24S-E ended October 31, 2021. C9300-24S is the current migration destination; the intermediate WS-C3850-24S-E replacement is also discontinued, rather than a current-product alternative.

WS-C3750X-24S-E identifies a stackable Catalyst 3750-X switch: WS-C3750X is the switch-family prefix, 24 is the port count, S identifies Gigabit Ethernet SFP ports, and E selects IP Services. The part number does not specify an installed uplink card; the base configuration has an empty network-module bay.
WS-C3750X-24S-E is managed through the Cisco IOS CLI over console, SSH or Telnet, plus SNMP monitoring. RJ-45 and USB Type-B console connections support local administration, while an Ethernet management port provides out-of-band access. SSH and cryptographic SNMPv3 require the cryptographic software image.
WS-C3750X-24S-E is discontinued: end of sale was October 30, 2016, and Cisco service ended October 31, 2021. Its original successor, WS-C3850-24S-E, is also discontinued, with end of sale on April 30, 2022. C9300-24S is the current migration destination after that intermediate replacement.
ORM Systems offers WS-C3750X-24S-E new sealed with up to 3-year extended ORM warranty or certified refurbished with up to 1-year ORM warranty. Both conditions have 30-day returns; terms apply. Cisco's enhanced limited lifetime hardware warranty ended October 31, 2021, and is separate from ORM's order warranty.
IP Base and IP Services are the license choices for Catalyst 3750-X fiber switches; WS-C3750X-24S-E includes IP Services. An IP Base 24-port fiber unit can upgrade using C3750X-24S-S-E paper licensing or L-C3750X-24S-S-E electronic licensing. Cisco IOS reads the installed license file at startup to activate the feature set.
C3KX-NM-1G, C3KX-NM-10G, C3KX-NM-10GT and C3KX-SM-10G are the uplink choices for WS-C3750X-24S-E. The base switch includes no uplink module. C3KX-NM-1G supplies four Gigabit ports; C3KX-NM-10G supplies two 10G SFP+ ports; C3KX-NM-10GT supplies two 10GBASE-T ports; C3KX-SM-10G supplies two 10G SFP+ service-module ports.
StackWise Plus stacks nine Catalyst 3750-X members and provides 64 Gbps stack throughput. Cable options include CAB-STACK-50CM=, CAB-STACK-1M= and CAB-STACK-3M=. LAN Base members cannot join an IP Base or IP Services stack. Confirm existing members' feature sets and the required cable lengths before specifying a stack extension.
WS-C3750X-24S-E supports full OSPF, EIGRP, BGPv4 and IS-ISv4 through IP Services, plus OSPFv3 and EIGRPv6. The routing template accommodates 11000 total unicast routes, comprising 3000 directly connected hosts and 8000 indirect routes. Template selection changes resource allocation, so confirm the intended routing configuration rather than assuming every maximum applies simultaneously.
No, WS-C3750X-24S-E ships with one C3KX-PWR-350WAC and an empty second power-supply bay, so internal redundancy is optional rather than included. An additional C3KX-PWR-350WAC= can be specified for the second bay. Confirm the supplied power configuration on the PO instead of assuming two installed supplies from the two-bay chassis.
WS-C3750X-24P-E has 24 Gigabit RJ-45 PoE+ ports, while WS-C3750X-24S-E has 24 non-PoE Gigabit SFP ports. Both models are discontinued. For legacy equipment matching, WS-C3750X-24P-E corresponds to powered copper endpoint connections, whereas WS-C3750X-24S-E corresponds to fiber connections that do not require endpoint power from the switch.
WS-C3750X-24S-E includes IP Services, whereas WS-C3750X-24S-S includes IP Base; both have 24 Gigabit SFP access ports. Full OSPF, EIGRP, BGPv4 and IS-ISv4 require IP Services. Both models are discontinued: the E version matches advanced legacy routing requirements, while the S version matches baseline routed-access configurations.
C9300-24S is the current migration destination, while Cisco service for WS-C3750X-24S-E ended October 31, 2021. The migration chain passes through WS-C3850-24S-E, which is also discontinued. WS-C3750X-24S-E remains a legacy matching or sparing purchase; C9300-24S is the option to evaluate for a current-product refresh rather than an intermediate replacement.
WS-C3750X-24S-E requires a full-width 1U rack position and measures 44.5 mm high, 445 mm wide and 460 mm deep, with a published weight of 7 kg. Check cabinet depth and space for rear power and stacking connections alongside front fiber connections before specifying the receiving rack location.
WS-C3750X-24S-E-RF is Cisco's remanufactured ordering PID, not ORM's certified refurbished condition. The corresponding base model is WS-C3750X-24S-E. Manufacturer remanufacturing and ORM inspection and bench testing are separate condition descriptions, so identify the intended condition explicitly on the PO rather than treating the two names as interchangeable.
