WS-C3750E-24TD-S provides 24 Gigabit Ethernet access ports and two fixed X2-based 10G uplink interfaces in a managed Layer 3 switch with IP Base. The access ports carry data without supplying endpoint power, so attached equipment needs its own power source. This Cisco Catalyst 3750-E model occupies a full-width 1U rack position and serves enterprise wiring-closet connections. The discontinued WS-C3750E-24PD-S differs by supplying PoE to its access ports. For a data-only Gigabit access switch, the defining purchasing distinction is the X2 uplink architecture: the chassis does not provide native SFP+ uplink sockets. Access-port autonegotiation accommodates existing 10/100/1000 Ethernet connections, while the included feature set supplies traffic classification, access control and basic routed-access functions.

160 Gbps switching capacity defines the internal fabric available to aggregate access traffic. 65.5 Mpps forwarding establishes the packet-rate envelope for traffic across the access and uplink interfaces. Static, RIPv1, RIPv2 and EIGRP Stub routing cover the included feature set; OSPF, BGPv4 and full EIGRP require IP Services rather than the supplied license. WS-C3750E-24TD-S carries 256 MB of DRAM and 64 MB of flash for running software and retaining the image. SDM templates change resource allocations: the VLAN template supports 12000 MAC entries, while the routing template supports 11000 total unicast routes. Those maxima belong to different profiles and are not simultaneous allocations. Four egress queues per port separate traffic classes for scheduling. 99W measured consumption at 100% throughput describes switch draw under traffic loading, not the rated output of C3K-PWR-265WAC. HSRP supports routed-link redundancy, while LACP provides link aggregation with compatible neighboring equipment.
Order WS-C3750E-24TD-S in new sealed or certified refurbished condition, specifying quantity, software entitlement and included accessories on the PO. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, X2 optics bay recognition, PSU status and fan status; firmware is verified and configurations are wiped to factory default. ORM's new-unit warranty is up to a 3-year extended term, certified refurbished coverage is up to 1 year, and every condition includes 30-day returns with terms applying; Cisco warranty and service ended January 31, 2018. Enterprise and volume POs are accepted, with Net-30 for government, RMA with advance replacement, and regional stock and RMA coverage across the UK, EU, US and MEA.

When replacing WS-C3750G-16TD-S or WS-C3750G-24TS-S, WS-C3750E-24TD-S is a named migration option for both older parts. Their end-of-sale dates were October 15, 2007 and March 16, 2009, respectively. Match software entitlement and add RCKMNT-E-1RU= when a spare rack mount kit is required before issuing the PO.
When adding a member to an existing Catalyst 3750-E stack, cable length becomes part of the hardware order. CAB-STACK-50CM=, CAB-STACK-1M= and CAB-STACK-3M= cover different rack spacing requirements. Local switching keeps same-member traffic off the stack ring. Specify cable PIDs and confirm member software before releasing the PO.
When staging a Catalyst 3750-E spare before production use, validate the intended configuration rather than ordering on port count alone. Generic On-Line Diagnostics (GOLD) checks hardware at boot and runtime, and 9216-byte jumbo frames require matching MTU choices. Specify the staging configuration and spare quantity before placing the PO.
Endpoint power through Ethernet ports
WS-C3750E-24TD-S does not supply PoE. C9300-24P-A is the current 24-port PoE+ migration choice, with Network Advantage rather than the legacy IP Base feature set.
Two internal redundant power supplies
WS-C3750E-24TD-S has one internal power supply slot, so two internal supplies cannot be installed. Redundant power requires the external PWR-RPS2300 instead.
Active Cisco hardware service coverage
Cisco service for WS-C3750E-24TD-S ended January 31, 2018. The current migration model is C9300-24T-A; the immediate replacement WS-C3750X-24T-S is also discontinued.

WS-C3750E-24TD-S identifies a Catalyst 3750-E data-only switch with 24 Gigabit access ports, two X2-based 10G uplinks and IP Base. WS-C3750E names the family, 24 gives the access-port count, TD identifies the data/uplink configuration, and S selects the IP Base software feature set.
Catalyst 3750-E switches are managed through the Cisco IOS CLI using the console or Telnet, with SSH available on a cryptographic image; Cisco Network Assistant and CiscoWorks LMS provide GUI and networkwide management. SNMPv1, SNMPv2c and SNMPv3 support monitoring. Specify the image and access method before ordering.
IP Base is included on WS-C3750E-24TD-S, and IP Services is available through software activation using 3750E-IPSLCB-QTY for the 24-port upgrade. Used-equipment relicensing options are LL-3750E-IPB= for IP Base and LL-3750E-IPS= for IP Services. Hardware condition does not replace the need to specify the software entitlement.
WS-C3750E-24TD-S is discontinued: end of sale was January 30, 2013, and Cisco support ended January 31, 2018. The replacement chain passes through discontinued WS-C3750X-24T-S and discontinued WS-C3850-24T-S before reaching C9300-24T-A. Buyers retaining the older hardware need reseller-backed sparing rather than an active Cisco service plan.
WS-C3750E-24TD-S is a migration replacement for WS-C3750G-16TD-S and WS-C3750G-24TS-S. WS-C3750G-16TD-S ended sale on October 15, 2007; WS-C3750G-24TS-S ended sale on March 16, 2009. The 16-port model moves to a 24-port configuration, while the older 1.5U model moves to a 1U chassis. Match software and uplink requirements before ordering.
WS-C3750E-24TD-S has two fixed 10G X2 uplink interfaces, not SFP+ sockets. X2-10GB-SR= and X2-10GB-LR= are compatible 10G optical choices. CVR-X2-SFP converts one X2 interface into two 1G SFP interfaces. Specify the optical type or converter configuration rather than assuming a standard SFP+ transceiver will fit.
Catalyst 3750-E supports a nine-member maximum StackWise Plus stack with 64 Gbps stack bandwidth. CAB-STACK-50CM=, CAB-STACK-1M= and CAB-STACK-3M= provide stacking-cable length choices. The family can join mixed stacks with discontinued Catalyst 3750 switches. Confirm the software image and cable lengths when adding a member to an existing stack.
Yes, WS-C3750E-24TD-S provides Layer 3 routing through Static, RIPv1, RIPv2 and EIGRP Stub under IP Base. OSPF, BGPv4, full EIGRP, PBR and PIM require IP Services. The 11000-route routing-template total is a hardware resource figure, not permission to use protocols excluded by the installed license.
WS-C3750E-24TD-S ships with C3K-PWR-265WAC, accepting 100-240V AC, and has one internal power supply slot. External PWR-RPS2300 provides the backup-power path rather than a second internal supply. Measured switch consumption is 99W at 100% throughput; C3K-PWR-265WAC's 265W rating is not the switch's measured operating draw.
Yes, WS-C3750E-24TD-S is a full-width 1U rack-mount switch measuring 44.5 mm high, 445 mm wide and 460 mm deep, with an 8.1 kg weight. RCKMNT-E-1RU= is the spare rack mount kit. Allow for rear connections and cooling through C3K-BLWR-60CFM= when checking cabinet clearance.
WS-C3750E-24PD-S supplies PoE on its 24 access ports, whereas WS-C3750E-24TD-S provides data-only ports. Both models are discontinued, so this comparison applies to legacy fleet compatibility and sparing. WS-C3750E-24TD-S fits nonpowered endpoint connections; WS-C3750E-24PD-S fits an existing installation that requires switch-delivered endpoint power.
WS-C3750E-24TD-E includes IP Services, while WS-C3750E-24TD-S includes IP Base. Both variants are discontinued and retain the same 24-port data configuration. IP Services enables the advanced routing feature set. The S variant suits legacy IP Base standardization; the E variant suits a legacy deployment already using those advanced routing entitlements.
WS-C3750E-24TD-S uses fixed X2 uplink interfaces, whereas C9300-24T-A uses modular uplinks. Uplink selection therefore follows different hardware choices on the two models. The discontinued WS-C3750E-24TD-S fits legacy X2 sparing; C9300-24T-A is the current migration choice when the uplink module needs to be selected for a new deployment.
ORM Systems offers WS-C3750E-24TD-S new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for refurbished units. Every condition includes 30-day returns; terms apply. Cisco's original 90-day limited hardware warranty is no longer active; Cisco service ended January 31, 2018.
