WS-C3750G-16TD-E is a Layer 3 managed switch with sixteen 10/100/1000 copper access ports, one fixed 10G XENPAK uplink interface and the IP Services software image. The access ports do not supply PoE. Its Rack-Mount 1U chassis belongs to the Cisco Catalyst 3750 Series, serving enterprise access and branch networks that require routed copper connectivity. The uplink uses XENPAK rather than SFP+ and has a 1.25:1 oversubscription ratio, which matters when sizing simultaneous upstream traffic. The discontinued WS-C3750G-16TD-S uses IP Base instead of the advanced routing image supplied here. This variant combines a smaller copper-port population with a dedicated high-speed uplink interface, rather than the more common twenty-four-port configuration found elsewhere in the family.

32 Gbps switching capacity defines the fabric bandwidth available for traffic handling. 35.7 Mpps forwarding rate provides the packet-processing figure for workload sizing. OSPF, EIGRP, BGPv4 and IS-ISv4 support dynamic routing; PBR controls selected traffic paths, while PIM-SM and PIM-DM support routed multicast. WS-C3750G-16TD-E carries 128 MB DRAM and 16 MB flash for runtime operation and image storage. Configurable limits reach 12000 MAC addresses and 11000 unicast routes, with Switching Database Manager templates allocating resources to the selected deployment. Administration includes the Cisco IOS CLI, browser-based initialization, Cisco Network Assistant and CiscoWorks; SSH requires a cryptographic image. Four egress queues per port allow separate treatment of traffic classes through scheduling and priority controls. The Catalyst 3750G-16TD has a fixed internal supply rather than interchangeable redundant power modules. 180W power consumption supplies the electrical planning figure for the AC feed and UPS capacity. External backup power connects through the separate RPS input.
Specify WS-C3750G-16TD-E in new sealed or certified refurbished condition, then confirm quantity, delivery region and included accessories before issuing the PO. Certified refurbished units are inspected and bench-tested for power-on and POST, every port linking at rated speed and clean boot; firmware is verified and configurations are wiped to factory default. ORM provides up to a 3-year extended warranty on new units and up to 1 year on certified refurbished units, with 30-day returns on every condition, terms apply; Cisco's original limited lifetime coverage ended with hardware support on October 13, 2012. Enterprise and volume orders can use accepted POs, Net-30 for government and RMA with advance replacement, with regional stock and RMA coverage across the UK, EU, US and MEA.

When extending an existing switch stack, cable reach determines the accessory order. CAB-STACK-50CM=, CAB-STACK-1M= and CAB-STACK-3M= provide distinct connection lengths. Measure the route between chassis and the return connection rather than assuming the shortest cable fits, then specify the required cable lengths and quantities on the purchase order.
When a lab needs numerous routed VLAN interfaces, planning starts with 128 recommended SVIs and a maximum of 1000 dependent on route and multicast entries. Match the intended interface population to the selected configuration, then specify the software image and staging requirements before issuing the purchase order.
When branch orders cover equipment rooms with different environmental conditions, humidity belongs in the acceptance checklist. Operation requires 10% to 85% relative humidity without condensation. Confirm that each installation space remains noncondensing during normal operation, then record the environmental checks required before ordering the site batch.
Switch-powered phones or access points
WS-C3750G-16TD-E does not supply PoE on its copper access ports; powered endpoints require separate power arrangements rather than switch-delivered power.
Two independent 10G uplink connections
The fixed uplink architecture provides one 10G XENPAK interface, so a second independent 10G uplink cannot be added to the same chassis.
Active Cisco hardware support eligibility
Cisco hardware support ended October 13, 2012. The current migration endpoint is C9300-24T-A, which changes copper access-port density from sixteen to twenty-four.

WS-C3750G-16TD-E identifies a Catalyst 3750 Gigabit Ethernet switch: WS-C3750G identifies the switch family, 16 denotes sixteen copper access ports, TD corresponds to the copper configuration with a 10G XENPAK uplink, and E selects IP Services. The final suffix distinguishes this advanced software image from the IP Base variant.
WS-C3750G-16TD-E supports the Cisco IOS CLI through console or Telnet, SSH with a cryptographic image, browser-based initialization, Cisco Network Assistant, Cisco CMS Software and CiscoWorks with SNMP. Select the management method before staging, and confirm the cryptographic image when encrypted remote administration is required.
WS-C3750G-16TD-E reached end of sale on October 15, 2007, and its last date of Cisco hardware support was October 13, 2012. Cisco hardware service has ended, so continued use relies on independent maintenance rather than a new Cisco hardware support entitlement.
ORM Systems offers WS-C3750G-16TD-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 limited lifetime coverage ended with hardware support on October 13, 2012. Refurbished units are inspected and bench-tested, with firmware verified and configurations wiped to factory default.
Catalyst 3750 software choices are IP Base and IP Services, with WS-C3750G-16TD-E supplied as an IP Services model. IP Base includes static routing, RIP and EIGRP Stub. IP Services adds advanced unicast, multicast and IPv6 routing, so software selection must follow the intended routing configuration rather than port count alone.
Nine switches can form a StackWise stack with WS-C3750G-16TD-E over a 32 Gbps interconnect. Dedicated stack connections preserve access ports for endpoints. Cable choices include CAB-STACK-50CM=, CAB-STACK-1M= and CAB-STACK-3M=. Specify lengths for adjacent connections and the return path rather than using Ethernet uplink cables.
WS-C3750G-16TD-E supports C3-XENPAK-10GB-LR= for 10 km single-mode links and XENPAK-10GB-ER for 40 km single-mode links through its 10G XENPAK slot. Both use SC fiber connections. Select the optic against fiber type and span, and confirm the remote optical interface before adding transceivers to the order.
WS-C3750G-16TD-E uses an internal AC supply, accepts 100-240V AC and has 180W power consumption. External backup connects through the RPS input using PWR-RPS2300 or PWR675-AC-RPS-N1=. The internal supply is not a modular redundant pair; size the AC feed and external backup separately when preparing the hardware order.
WS-C3750G-16TD-E provides advanced IPv4, IPv6 and multicast routing through IP Services, including OSPF, EIGRP, BGPv4, IS-ISv4, PBR and PIM routing modes. Inter-VLAN routing is supported in hardware. The configurable unicast route total reaches 11000, with resource allocation selected through Switching Database Manager templates for the intended configuration.
Catalyst 3750G-16TD occupies 1U and measures 44 mm high, 445 mm wide and 409 mm deep, with a weight of 5.7 kg. Check usable rack depth and cable clearance before specifying the installation position, particularly where rear power and stack connections share limited access space.
WS-C3750G-16TD-E includes IP Services, whereas WS-C3750G-16TD-S includes IP Base; both variants are discontinued. The E model supports advanced unicast, multicast and IPv6 routing. Buyers maintaining advanced routed legacy configurations require the E feature set, while static routing, RIP and EIGRP Stub requirements align with the S variant.
WS-C3750G-24PS-E supplies PoE, whereas WS-C3750G-16TD-E has no PoE output; both models are discontinued. The PoE variant also has twenty-four copper access ports rather than sixteen. Compare the former when maintaining powered-endpoint installations and the latter when matching an existing non-PoE sixteen-port switch.
C9300-24T-A has twenty-four Gigabit copper access ports, whereas WS-C3750G-16TD-E has sixteen. C9300-24T-A is the current endpoint of the migration chain, while WS-C3750G-16TD-E is discontinued. Current twenty-four-port builds can use C9300-24T-A; the older model fits purchase orders matching existing sixteen-port legacy hardware.
C9300-24T-A is the current migration endpoint for WS-C3750G-16TD-E, whose original replacement was the now-discontinued WS-C3750E-24TD-E. The chain then passed through the discontinued WS-C3750X-24T-E and WS-C3850-24T-E. The current endpoint has twenty-four data ports, so migration changes access-port density rather than preserving the original sixteen-port configuration.
