IE-3505-8T3S-A is a fanless Layer 3 industrial switch with eight Gigabit copper access ports, three fixed 1G SFP uplinks, and Network Advantage. The DIN rail chassis serves factory automation, process control, energy, and transportation installations. Copper ports carry data without supplying endpoint power; IE-3505-8P3S-A is the nearest powered sibling, providing PoE/PoE+ instead. The Cisco IE3500 Rugged Series separates fixed fiber uplinks from endpoint connections, so access-port expansion does not change the uplink speed. Specify this configuration when equipment has independent power and the industrial network requires advanced routing rather than Ethernet connectivity alone.
IE-3505-8T3S-A price is $6,135.15, a 38.1% saving from the Cisco list price of $9,905.00. IE-3505-8T3S-A is in stock and available for next-day dispatch. (terms applied)

OSPF, BGP, EIGRP, and ISIS support routed industrial connections under the included network license. IE-3505-8T3S-A accommodates 24000 MAC addresses for endpoint aggregation. The IE3505 Rugged Series adds an FPGA for advanced redundancy functions, including HSR and PRP. Line-rate forwarding covers every port and packet size, while eight queues provide traffic scheduling. Internal flash provides 5.1 GB of user-accessible storage for software and configuration files. HSR and PRP require Cisco IOS XE 26.1.1 or later on the base switch; expansion-module support must be checked against the intended release.
ORM Systems offers IE-3505-8T3S-A new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to a 1-year warranty for certified refurbished units; every condition includes 30-day returns, terms apply. Refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, and optics bay recognition, with firmware verified and configuration wiped to factory default. Select the condition and confirm the accessory and license line items before placing the order; Cisco's platform hardware warranty term is five years. For enterprise and volume orders, POs are accepted, Net-30 is available for government, and RMA includes advance replacement across UK, EU, US, and MEA.

A cabinet retrofit adding wired machines can use IEM-3500-16T= to add sixteen copper Gigabit interfaces and reach 27 total ports. Include the expansion module as a separate order item, check the available mounting space, and size the external supply for the completed assembly before approving the purchase order.
Industrial cells requiring separate routed interfaces can use 32 SVIs and VRF-lite. Map the required interfaces and routing domains before choosing the configuration. Confirm the routing features required by the control network, then specify the corresponding network license and configuration requirements on the purchase order.
Bench staging before cabinet installation can use the RJ-45 or USB-C console connection. USB connections are intended for service operations rather than continuous use. Establish the staging connection and configuration workflow before delivery, then specify the console-access requirements with the hardware order rather than leaving commissioning access unresolved.
PoE power on base ports
IE-3505-8T3S-A provides data-only copper ports and cannot accept PoE expansion modules. IE-3505-8P3S-A supplies PoE/PoE+ through eight base ports instead.
10G fiber uplinks to aggregation
IE-3505-8T3S-A has fixed 1G uplinks. IE-3500-8T3X-A provides three 10G SFP+ uplinks but does not include the IE3505 advanced redundancy FPGA.

IE-3505-8T3S-A identifies an advanced modular IE3500 industrial switch: IE-3505 is the advanced base, 8T means eight Gigabit copper ports, 3S means three Gigabit SFP ports, and A means Network Advantage. The configuration is data-only; the suffix does not indicate PoE or 10G uplinks.
IE-3505-8T3S-A supports WebUI, CLI through SSH or Telnet, RJ-45 or USB-C console access, Catalyst Center, and Meraki dashboard management. Meraki cloud management requires Cisco IOS XE 26.1.1 or later. Select local, on-premises, or cloud management before specifying the management license and commissioning requirements.
Cisco has not announced an end-of-sale date for IE3500 Rugged. IE-3505-8T3S-A remains an available industrial switch. For a new purchase order, specify the exact part number and condition rather than treating the model as a discontinued replacement-only item.
IE-3505-8T3S-A is offered new sealed or certified refurbished. Cisco's hardware warranty term is five years. ORM coverage is up to three years extended for new units or up to one year for certified refurbished units. Every condition has 30-day returns; terms apply.
IE-3505-8T3S-A includes perpetual Network Advantage and requires a Smart Account. Optional Cisco DNA Essentials or Cisco DNA Advantage subscriptions have three-, five-, or seven-year terms. Meraki management uses Enterprise LIC-IE3500-E or Advantage LIC-IE3500-A. A Cisco DNA subscription is not mandatory for standalone operation.
IE-3505-8T3S-A provides no endpoint power, whereas IE-3505-8P3S-A supplies PoE/PoE+ on eight copper ports. Endpoint power delivery cannot be added through a software upgrade. Choose the data-only model for independently powered equipment; specify the PoE model when endpoints must receive power over Ethernet.
IE-3505-8T3S-A includes Network Advantage, whereas IE-3505-8T3S-E includes Network Essentials. Advantage adds routing capabilities including BGP, EIGRP, and ISIS. Specify the Advantage model when those protocols are required; choose Essentials when the required switching and routing functions fit the lower-tier feature set.
IE-3500-8T3X-A provides three 10G SFP+ uplinks, while IE-3505-8T3S-A provides three 1G SFP uplinks. Confirm the aggregation link speed before selecting optics. The 10G model suits a 10G uplink requirement; the 1G model suits installations whose fiber connections operate at Gigabit speed.
IE-3505-8T3S-A accepts external DC power through DC-A and DC-B and operates from one or two supplies. With both sources working, the higher-voltage source supplies power; the other takes over if that source fails. Specify independently capable supplies and check the input voltage before wiring.
IE3500 Rugged accepts one expansion module at a time, and expansion modules are not hot-swappable. IE-3505-8T3S-A supports non-PoE options IEM-3500-8T=, IEM-3500-8S=, IEM-3500-16T=, IEM-3500-6T2S=, and IEM-3500-14T2S=. Select the copper and fiber mix before ordering; PoE modules require a PoE-capable host.
