WS-C3750G-48TS-E is a managed Layer 3 enterprise access switch with 48 10/100/1000 RJ-45 ports and four fixed Gigabit SFP uplinks. The data-only configuration supplies no PoE output, so connected computers, printers and other Ethernet endpoints require independent power. Its full-width 1U chassis places the Catalyst 3750G in rack-based access installations. IP Services is the included Cisco IOS software feature set, supporting dynamic unicast routing, hardware-based IPv6 routing and multicast routing rather than limiting the purchase to basic switching. The discontinued WS-C3750G-48PS-E adds PoE to the corresponding powered-port configuration. Uplink architecture remains a hardware choice: this model has built-in SFP interfaces, not an empty network-module bay that can accept a higher-speed uplink card.
WS-C3750G-48TS-E price for new stock is $871.50. WS-C3750G-48TS-E refurb price is $164.43. WS-C3750G-48TS-E is in stock and available for next-day dispatch. (terms applied)

32 Gbps switching capacity defines the forwarding fabric, while 38.7 Mpps forwarding characterizes processing of 64-byte packets. Static, RIPv1, RIPv2, OSPF, EIGRP and BGPv4 provide unicast routing options; PBR redirects selected traffic, while PIM-SM and PIM-DM support multicast routing. The configurable hardware scale reaches 11000 unicast routes, establishing the route-table ceiling to check against the intended configuration. WS-C3750G-48TS-E combines 128 MB DRAM with 32 MB flash for running software and stored images. A configurable 12000-entry MAC table sets the address-learning capacity for connected endpoints. Catalyst 3750 management includes Cisco IOS CLI access, browser-based initialization, Cisco Network Assistant and CiscoWorks integration; SSH requires a cryptographic software image. 152W measured at 100% throughput provides a full-traffic reference for electrical planning, not a maximum-draw specification. External backup power connects through PWR-RPS2300 or PWR675-AC-RPS-N1=, rather than a second internal supply bay. These external systems supply DC power through the rear redundant-power connector when the internal supply fails.
WS-C3750G-48TS-E is offered new sealed or certified refurbished, with ORM warranties of up to 3-year extended coverage on new units and up to 1 year on certified refurbished units; Cisco's original limited lifetime hardware warranty ended January 31, 2018. Certified refurbished units are inspected and bench-tested for power-on and POST, clean boot, rated-speed port links, optics bay recognition and stack adapter negotiation, with firmware verified and configuration wiped to factory default. Specify condition, quantity and required accessories on the PO; every condition carries 30-day returns, terms apply. For enterprise and volume POs, ORM Systems accepts purchase orders, offers Net-30 for government, and provides regional stock and RMA handling across UK, EU, US and MEA, including RMA with advance replacement.

When an existing stack needs another member, all members must run the same Cisco IOS version. Automatic version checking and updating allows the master to align an added member with its software. Identify the intended master image and verify software alignment during staging before authorizing the hardware PO.
When a routed-access configuration is being staged, the recommendation of 128 switch virtual interfaces provides a planning checkpoint before configuration is copied. Switching Database Manager templates allocate resources for access, routing or VLAN use. Specify the intended template and review the routed-interface count before the PO.
When an application migration requires larger Ethernet frames, Gigabit bridging supports a 9000-byte MTU and a maximum 9018-byte frame. Validation should include neighboring interfaces and application frame settings rather than assuming every connected device accepts the same size. Specify the tested frame configuration before ordering hardware for the migration.
10G uplinks on this chassis
WS-C3750G-48TS-E has fixed 1G SFP uplinks without a removable uplink-card bay. C9300-48T-A with C9300-NM-8X provides a current alternative with modular 10G SFP+ uplinks.
Power over Ethernet for endpoints
WS-C3750G-48TS-E cannot supply endpoint power through its access ports. C9300-48P-A is a current 48-port PoE+ alternative; specify its power configuration against the intended endpoint load.
Continuing Cisco hardware service coverage
Cisco hardware service for WS-C3750G-48TS-E ended January 31, 2018. C9300-48T-A is the current migration target when a purchase requires a supported replacement rather than legacy hardware.

WS-C3750G-48TS-E identifies a Catalyst 3750G switch with the IP Services software image. WS-C3750G names the Gigabit switching family; 48 specifies the access-port count; TS corresponds to copper Ethernet access ports plus SFP uplinks; E selects IP Services. The configuration has 48 10/100/1000 ports and four Gigabit SFP ports.
The Catalyst 3750G supports Cisco IOS CLI management through the local console, Telnet or SSH, browser-based setup, Cisco Network Assistant and CiscoWorks using SNMPv1/v2c/v3. SSH requires a cryptographic software image. Stack management uses one IP address, while the browser setup utility initializes addressing and passwords.
WS-C3750G-48TS-E is discontinued: end of sale was January 30, 2013, and hardware support ended January 31, 2018. Its original replacement, WS-C3750X-48T-E, is also discontinued, followed by the discontinued WS-C3850-48T-E. The forward migration chain ends at the current C9300-48T-A, rather than either intermediate model.
ORM Systems offers WS-C3750G-48TS-E new sealed with up to 3-year extended warranty coverage, or certified refurbished with up to 1 year of warranty coverage. Both conditions include 30-day returns; terms apply. Cisco's original limited lifetime hardware warranty and service ended on January 31, 2018.
WS-C3750G-48TS-E includes the IP Services software image, which supplies advanced unicast, IPv6 and multicast routing capabilities. The IP Base image is the other family option. CD-3750G-48EMI= upgrades standard-image 48-port Gigabit models; the E configuration already includes the higher routing feature set, so that upgrade kit is not required.
WS-C3750G-48TS-E supports GLC-SX-MM= and GLC-LH-SM= transceivers for its Gigabit SFP interfaces, providing SX and LH fiber connection options respectively. GLC-ZX-SM= is another listed Gigabit fiber option. Transceiver selection must match the fiber installation and remote interface; these SFP interfaces are not 10G SFP+ uplinks.
WS-C3750G-48TS-E supports nine members in a Cisco StackWise stack using a 32 Gbps interconnect. CAB-STACK-50CM= provides a 50 cm cable, CAB-STACK-1M= provides a 1 m cable, and CAB-STACK-3M= provides a 3 m cable. Dedicated stack connections leave the Ethernet access and SFP uplink ports available for network traffic.
WS-C3750G-48TS-E supports Static, RIPv1, RIPv2, RIPng, OSPF, EIGRP and BGPv4 routing with its IP Services image. OSPFv6 and EIGRPv6 provide IPv6 routing, while PIM-SM and PIM-DM support multicast routing. PBR and HSRP are also available. The configurable hardware scale is 11000 unicast routes, not a separate allocation for every protocol.
No, WS-C3750G-48TS-E does not provide redundant internal power-supply modules. Backup power comes through an external PWR-RPS2300 or PWR675-AC-RPS-N1= connected to the rear redundant-power receptacle. The external system supplies DC power when the internal supply fails; purchasing another internal supply module does not create a redundant configuration in this chassis.
The Catalyst 3750G-48TS is a full-width Rack-Mount 1U switch, not a compact desktop model. Its chassis measures 44 mm high, 445 mm wide and 409 mm deep, with a weight of 6.4 kg. Operating temperature is 0°C to 45°C, so cabinet selection must account for chassis depth and the installation environment.
WS-C3750G-48TS-E measures 152W at 100% throughput and 134W at 5% throughput under the stated normal test conditions. Those figures describe measured switch consumption rather than endpoint power delivery. The internal supply's rated maximum is 160W; that supply rating should not be substituted for the measured consumption figure.
WS-C3750G-48PS-E supplies PoE on its access ports, whereas WS-C3750G-48TS-E supplies data connectivity without endpoint power. Both variants are discontinued. For retained installations, the TS configuration matches independently powered endpoints; the PS configuration addresses powered endpoints subject to its shared power budget, rather than unrestricted maximum power on every port.
WS-C3750G-48TS-E includes IP Services, whereas WS-C3750G-48TS-S includes IP Base. Both models are discontinued. IP Services adds advanced unicast, hardware-based IPv6 and multicast routing; IP Base includes static routing, RIP and EIGRP Stub. Retained routed-access configurations need the E feature set, while configurations using the narrower routing functions can use the S image.
C9300-48T-A uses modular uplinks, whereas WS-C3750G-48TS-E has four fixed Gigabit SFP uplinks. The original model is discontinued and Cisco hardware service has ended. Buyers maintaining the original fixed-uplink installation can match its existing hardware; current migration orders use C9300-48T-A and must specify the required uplink module rather than assume fixed ports are included.
