WS-C3750G-16TD-S combines sixteen 10/100/1000 RJ-45 ports and one fixed 10G XENPAK transceiver slot in a stackable Layer 3 enterprise access switch. The copper ports are non-PoE, so connected endpoints need their own power source rather than drawing power from the switch. The Catalyst 3750 serves wiring-closet access and aggregation duties within enterprise branch networks. Its 1U rack-mount chassis carries the IP Base software image for the supplied feature set. The discontinued WS-C3750G-16TD-E sibling carries IP Services instead for advanced-routing configurations. Cisco Catalyst 3750G-16TD optical connectivity requires compatible XENPAK hardware, which matters when matching an existing fiber connection. Access control lists and port-based authentication provide traffic and identity controls, while per-port policing and egress scheduling distinguish traffic classes.

32 Gbps switching capacity defines the forwarding fabric, while 35.7 Mpps forwarding provides the packet-processing limit independently of the uplink line speed. Static routing, RIPv1, RIPv2, and EIGRP Stub support routed access; HSRP provides gateway redundancy, while full OSPF, BGPv4, PBR, and PIM require the higher-feature image. WS-C3750G-16TD-S has 128 MB DRAM and 16 MB flash for runtime operation and image storage. Configurable ceilings reach 12000 MAC entries and 11000 unicast routes, with Switching Database Manager templates allocating resources to the selected workload. STP, RSTP, MSTP, and LACP control loop prevention and link aggregation. Management includes the Cisco IOS CLI, browser-based device manager, Cisco Network Assistant, CiscoView, and SNMP; SSH requires a cryptographic image. 180W power consumption supplies the electrical planning figure for the fixed internal AC supply, with an operating input of 100-240V AC. Fixed fans provide cooling, and the chassis has no redundant hot-swappable internal PSU bays.
WS-C3750G-16TD-S is available new sealed with up to a 3-year extended ORM warranty or certified refurbished with up to 1 year; both conditions have 30-day returns, terms apply, while Cisco's original limited lifetime coverage ended October 13, 2012. Certified refurbished units are inspected and bench-tested for power-on, POST, clean boot, rated-speed port links, PSU status, fan status, and stack adapter negotiation, with firmware verified and configuration wiped to factory default. Specify condition, quantity, and accessories on the PO. For enterprise and volume orders, ORM accepts POs, offers Net-30 for government, and provides RMA with advance replacement across UK, EU, US, and MEA.

An existing stack requiring another member needs an installation sequence, not just a matching chassis. Power off the added unit before connecting it; a switch powered first becomes the initial master, with other members started approximately 10 seconds later. Specify the intended master and shutdown procedure before the PO.
A branch rollout that moves inter-VLAN routing into the access switch needs an interface plan before hardware quantities are fixed. The recommended configuration is 128 SVIs, while the maximum reaches 1000 depending on route and multicast entries. Specify the required interface count and memory-allocation template before the PO.
A multi-site hardware standardization order needs an installation check for every cabinet, including units intended as regional spares. Allow at least 76 mm around ventilation openings so adjacent equipment does not restrict airflow. Record cabinet clearances and mounting arrangements at each site before setting quantities on the PO.
Powered endpoints without local power
WS-C3750G-16TD-S supplies no PoE on its copper ports. Phones, access points, or other powered devices therefore require their own power source rather than relying on the network connection.
OSPF or BGPv4 as shipped
The supplied IP Base image supports static routing, RIP, and EIGRP Stub, not full OSPF or BGPv4. Advanced unicast routing requires the IP Services image.
Unoversubscribed 10G uplink forwarding
The XENPAK uplink is 1.25:1 oversubscribed. Workloads requiring unoversubscribed 10G forwarding should not treat the advertised interface speed as a guarantee of full-rate throughput.
Active Cisco hardware support
Cisco hardware service for WS-C3750G-16TD-S ended October 13, 2012. The migration chain ends at C9300-24T-A, a 24-port data switch rather than this 16-port configuration.

WS-C3750G-16TD-S identifies a Catalyst 3750 Gigabit Ethernet switch: WS-C3750G is the model prefix, 16 is the access-port count, TD denotes copper access with a 10G XENPAK interface, and S denotes IP Base. The configuration has no PoE, and the optical interface requires a compatible XENPAK transceiver.
The Catalyst 3750 is managed through the Cisco IOS CLI over console, Telnet, or SSH with a cryptographic image, plus a browser-based device manager, Cisco Network Assistant, CiscoView, and SNMP. Cisco Network Assistant is a PC application; the device manager resides in switch memory. A stack is managed through one IP address.
WS-C3750G-16TD-S reached end of sale on October 15, 2007, and Cisco hardware support ended October 13, 2012. The original replacement, WS-C3750E-24TD-S, is also discontinued. The later migration chain ends at C9300-24T-A, so an original replacement recommendation must not be mistaken for a current model.
ORM Systems offers WS-C3750G-16TD-S 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 hardware warranty and service ended October 13, 2012. Refurbished units are inspected, bench-tested, firmware verified, and wiped to factory default.
IP Base is supplied with WS-C3750G-16TD-S; IP Services is the higher-feature image for advanced routing. OSPF, BGPv4, PBR, and PIM require IP Services rather than the supplied image. Advanced-routing capability therefore depends on the appropriate software image and entitlement, not simply on having the same physical ports and chassis.
C3-XENPAK-10GB-SR, C3-XENPAK-10GB-LR, and XENPAK-10GB-ER are supported for the Catalyst 3750G-16TD switch. C3-XENPAK-10GB-SR reaches 300 m on OM3 multimode fiber; C3-XENPAK-10GB-LR reaches 10 km and XENPAK-10GB-ER reaches 40 km on single-mode fiber. All use SC connectors, so the optical connection needs matching fiber termination as well as a supported transceiver.
Nine switches can form a WS-C3750G-16TD-S StackWise stack using a 32-Gbps interconnect. CAB-STACK-50CM=, CAB-STACK-1M=, and CAB-STACK-3M= provide the supported cable lengths. The two rear StackWise ports create the stack connection, and a complete cable ring is needed for full bandwidth and redundant connections.
No, WS-C3750G-16TD-S provides no PoE on any of its sixteen copper access ports. The unit therefore cannot power phones, wireless access points, or other endpoints through those connections. Connected devices must have another power source; the switch's internal supply powers the chassis rather than delivering endpoint power through Ethernet.
No, WS-C3750G-16TD-S has a fixed internal supply rather than redundant hot-swappable PSU bays. External backup power is supported through PWR-RPS2300 or PWR675-AC-RPS-N1=. These systems connect to the rear RPS connector; they do not convert the chassis into a dual-internal-PSU configuration. External backup equipment is an additional order item when required.
Static routing, RIPv1, RIPv2, EIGRP Stub, and HSRP are available on WS-C3750G-16TD-S under IP Base. The switch supports inter-VLAN routing, but full OSPF and BGPv4 require IP Services. The configurable ceiling is 11000 unicast routes; resource allocation depends on the selected Switching Database Manager template.
WS-C3750G-16TD-E carries IP Services, while WS-C3750G-16TD-S carries IP Base. Both are discontinued. The IP Services image enables advanced unicast routing, including OSPF and BGPv4. The IP Base variant fits a matching legacy spare; the enhanced-image variant fits an existing advanced-routing configuration, not a current equipment refresh.
WS-C3750G-24PS-S provides PoE, whereas WS-C3750G-16TD-S is non-PoE. Both are discontinued legacy models. The power distinction matters when phones or wireless access points need electricity from their network connection. The non-PoE model fits separately powered endpoints; the PoE sibling fits maintenance of an existing port-powered installation.
C9300-24T-A has 24 copper access ports compared with sixteen on WS-C3750G-16TD-S. C9300-24T-A is the endpoint of the later migration chain, not a like-for-like 16-port spare. The older configuration fits an existing legacy inventory requirement; the current model fits a refresh requiring 24 access connections.
WS-C3750G-16TD-S is a 1U rack-mount switch measuring 44 mm high, 445 mm wide, and 409 mm deep. Its 5.7 kg weight and rear connections belong in cabinet planning. At least 76 mm of ventilation clearance is required, together with access to the rear console, power, and stacking connections.
