WS-C3750G-24TS-E1U is a managed Layer 3 access switch with 24 Gigabit copper ports, four fixed 1G SFP uplinks and the IP Services software feature set. Its non-PoE configuration connects separately powered endpoints, while the full-width 1U chassis fits a standard equipment rack. The Cisco Catalyst 3750 Series combines access switching with routing at the enterprise network edge. Fixed uplinks keep the upstream connection architecture independent of removable network cards, making the installed fiber interfaces an important part of replacement planning. The discontinued WS-C3750G-24PS-E adds PoE for powered endpoints; this model retains data-only copper access. For a legacy wiring closet, the distinction is whether endpoint power comes from the access switch or from another source.

32 Gbps switching capacity provides the switching fabric for access and uplink traffic. 38.7 Mpps forwarding at 64-byte packet size establishes the packet-processing figure for this hardware. OSPF, EIGRP, BGPv4 and IS-ISv4 support routed access under IP Services, while PBR enables policy-directed forwarding and PIM-SM supports multicast routing. WS-C3750G-24TS-E1U carries 128 MB DRAM and 32 MB flash for software operation and image storage. The Cisco Catalyst 3750G-24TS-1U supports configurable maxima of 12000 MAC addresses and 11000 unicast routes, so address and route requirements belong in configuration sizing. STP, RSTP and multiple spanning-tree operation cover redundant Layer 2 paths, while cross-stack EtherChannel permits link aggregation across members. Measured consumption of 94W at full throughput and 82W at 5% throughput provides operating-load reference points rather than a single constant draw. Power-source backup uses an external redundant power system rather than a second internal supply.

Replacing an older wiring-closet unit starts with chassis and image matching, not only port count. WS-C3750G-24TS-E1U replaced the 1.5-rack-unit WS-C3750G-24TS-E. Review mounting space, retained connections and the saved configuration, then specify the complete replacement PID and required accessories on the purchase order.
When extending an installed stack, the management relationship matters alongside the physical connections. Catalyst 3750 members operate as one logical switch with a single management IP address and an elected master. Review the existing member inventory and master configuration, then specify the intended member role before issuing the PO.
When purchasing hardware for a routed access configuration, count the required switch virtual interfaces before selecting the software configuration. Catalyst 3750 recommends 128 SVIs and supports a maximum of 1000 depending on route and multicast entries. Check the combined configuration requirements and specify the intended interface allocation before the PO.
Switch-powered phones and access points
WS-C3750G-24TS-E1U supplies no PoE to endpoints. C9300-24P-A is a current replacement-chain option with 24 PoE+ access ports and Network Advantage, rather than the legacy IP Services image.
Native 10G uplinks to distribution
WS-C3750G-24TS-E1U has four fixed 1G SFP uplinks and no removable uplink-module bay. A requirement for native 10G upstream ports needs different hardware; adding stack members does not change these ports.
Active Cisco hardware support
Cisco service for WS-C3750G-24TS-E1U ended January 31, 2018. C9300-24T-A is the current endpoint of the replacement chain; the intervening replacement models are also discontinued.

WS-C3750G-24TS-E1U identifies a Gigabit Catalyst 3750 configuration: WS-C3750G is the hardware prefix, 24 is the copper access-port count, TS describes copper access with SFP uplinks, E identifies IP Services and 1U identifies chassis height. The complete configuration includes 24 10/100/1000 ports and four Gigabit SFP uplinks.
WS-C3750G-24TS-E1U supports CLI through the console, Telnet or SSH, browser-based setup, Cisco Network Assistant, Cisco CMS Software, CiscoWorks and SNMPv1/v2c/v3. SSH and encrypted SNMPv3 require a cryptographic software image. Stacked units are administered as one logical switch, so specify the required image and management method when ordering.
IP Services is the included software feature set for WS-C3750G-24TS-E1U; the family also offers IP Base. The IP Base-to-IP Services upgrade for this hardware is CD-3750G-EMI=. Confirm the installed image and required routing functions when ordering a refurbished unit; SSH additionally requires a cryptographic software image.
Yes, WS-C3750G-24TS-E1U reached end of sale on January 30, 2013, and its last date of Cisco support was January 31, 2018. Software maintenance ended January 30, 2014. Cisco service has ended, so a purchase must be evaluated as legacy hardware rather than an actively supported Cisco installation.
ORM Systems offers WS-C3750G-24TS-E1U new sealed with up to 3-year extended warranty or certified refurbished with up to 1 year. Both conditions have 30-day returns, terms apply. Cisco’s original limited lifetime warranty is no longer active; Cisco service and support ended January 31, 2018.
WS-C3750G-24TS-E1U replaced WS-C3750G-24TS-E, the older 1.5-rack-unit IP Services model. The predecessor’s end-of-sale date was March 16, 2009. The replacement reduced chassis height to one rack unit and increased flash from 16 MB to 32 MB. Both are discontinued, so retain these identities for legacy replacement matching.
The Catalyst 3750G-24TS-1U has four fixed Gigabit SFP uplinks, not 10G SFP+ uplinks or a removable network-module bay. GLC-SX-MM= provides SX fiber connectivity and GLC-LH-SM= provides LH connectivity. Specify the transceiver PID according to the installed fiber and the remote interface when preparing the hardware order.
StackWise connects nine Catalyst 3750 members through a 32 Gbps stack interconnect, using dedicated stacking ports rather than access ports. Cable options are CAB-STACK-50CM=, CAB-STACK-1M= and CAB-STACK-3M=. Catalyst 3750 and Catalyst 3750-E switches can share a stack, which operates as one logical switching unit.
Yes, WS-C3750G-24TS-E1U provides Layer 3 routing with IP Services, including OSPF, EIGRP, BGPv4, IS-ISv4 and PBR. IPv6 routing includes OSPFv6 and EIGRPv6. The configurable unicast-route maximum is 11000 routes; routing-table allocation must also account for the intended multicast and interface configuration.
The Catalyst 3750G-24TS-1U consumes a measured 94W at 100% throughput and 82W at 5% throughput under controlled operating conditions. These are operating-load reference figures. The separate 100W figure is the power-supply rated maximum, not a measured consumption value, and should not be substituted for either operating measurement.
WS-C3750G-24TS-E1U supports external redundant power rather than a second internal PSU. The internal supply accepts 100-240V AC; external options include PWR-RPS2300 and PWR675-AC-RPS-N1=. Associated connection options are CAB-RPS2300= and CAB-RPS-1614=. Specify the selected external system and its matching connection cable together on the purchase order.
WS-C3750G-24TS-E1U is non-PoE, whereas WS-C3750G-24PS-E supplies PoE on its 24 copper access ports. Both retain four Gigabit SFP uplinks and IP Services. Both are discontinued: the former matches separately powered legacy endpoints, while the latter matches legacy installations requiring power delivery from the access switch.
WS-C3750G-24TS-E1U ships with IP Services, while WS-C3750G-24TS-S1U carries IP Base. Advanced protocols such as OSPF and EIGRP require IP Services. Both models are discontinued; the E1U unit matches advanced-routing legacy configurations, and the S1U unit matches installations retaining the IP Base feature set.
WS-C3750G-24TS-E1U reached end of sale on January 30, 2013; C9300-24T-A is the current endpoint of its replacement chain. The intervening WS-C3750X-24T-E and WS-C3850-24T-E are also discontinued. Choose the older switch for legacy matching; specify C9300-24T-A when purchasing current replacement hardware.
Yes, the Catalyst 3750G-24TS-1U is a full-width 1U rack-mount switch measuring 44 mm high, 445 mm wide and 378 mm deep, with a weight of 5.5 kg. Its operating temperature range is 0°C to 45°C. Confirm rack depth and the supplied mounting hardware before finalizing the order.
