IE-3500-8P3S-E Description
The IE-3500-8P3S-E is a Cisco IE3500 Rugged Series modular industrial Ethernet switch for DIN-rail cabinets that power field devices and hand traffic off over fiber. The switch has eight Gigabit PoE/PoE+ copper ports, three 1G/100M SFP uplinks and a 240W PoE budget that reaches 360W with an expansion module, on a 12V to 54V DC input and an operating range of -40 to +75°C in a forced-air enclosure. PoE needs 48VDC at the input and PoE+ needs 54VDC, and the switch has no built-in power supply.

Product Performance
Key Features
The base switch provides 240W for PoE, and the total reaches 360W once an expansion module is attached. PoE runs from 48VDC at the input and PoE+ from 54VDC, so the DC feed decides which endpoint classes can be powered.
Two DC terminals, DC-A and DC-B, accept separate feeds. With both live, the switch draws from the higher-voltage one and keeps running on the other if a feed fails.
An IEM-3500 module adds 8 or 16 ports, taking the system to 19 or 27. PoE modules such as IEM-3500-8P= and IEM-3500-16P= attach to this PoE-capable base, and a module’s power draw counts against the host input.
The three SFP slots run at 1G or 100M. Industrial-grade fiber parts such as GLC-FE-100FX-RGD= (2 km) and GLC-FE-100LX-RGD= (10 km) are supported, and commercial or extended-temperature SFPs reduce the allowed operating temperature.
REP rings, PROFINET MRP, EtherNet/IP and PTP v2 are part of Network Essentials. PRP, HSR and DLR are not available on this switch.
The switch is fanless and rated -40 to +70°C with 40 LFM of airflow, -40 to +60°C in a sealed enclosure and up to +75°C with 200 LFM or more. Class I Division 2 hazardous-location approvals apply when it is installed in a suitable enclosure.
Application Scenarios
On a factory floor, the switch powers IP cameras and wireless access points from its PoE/PoE+ ports while PLC traffic returns to the plant backbone over the SFP uplinks. The DIN-rail body fits the same cabinet as the controllers.
In a roadside intelligent-transportation cabinet, the switch feeds cameras and sensors over PoE and carries their streams to the control center on fiber. A fan or blower-equipped enclosure keeps it within its +75°C rating.
At a water pumping station, the switch powers cameras and radios on the DC bus from the same panel, using industrial-grade SFPs for the fiber run back to the treatment plant.

IE-3500-8P3S-E is the PoE model of its pair: its 8 copper ports supply PoE/PoE+ from a 240W base budget, rising to 360W with expansion modules, while IE-3500-8T3S-E has the same 11-port layout with no PoE and suits cabinets without powered devices. Sites that need 4PPoE devices together with 10G uplinks move to IE-3500-8U3X-E, which is rated 480W and carries three 10G/1G SFP+ ports. IE-3500-8P3S-E is Network Essentials; Network Advantage on the same hardware is IE-3500-8P3S-A, or an installed switch can be upgraded later with IE3500-NW-A=. Against IE-3400-8P2S-E, it adds a third SFP uplink and raises the table to 24000 MAC addresses and 1024 active VLANs from 16K and 256.

Ordering Checklist
- Power supply: No supply is included. Order a PoE-capable unit such as PWR-IE65W-PC-AC=, PWR-IE170W-PC-AC=, PWR-IE240W-PCAC-L= or PWR-IE480W-PCAC-L=, sized for the switch, modules and PoE load. An undersized or non-PoE supply (PWR-IE50W-AC= variants) leaves the PoE ports without the budget the load needs.
- Expansion module: Add an IEM-3500 module such as IEM-3500-8T=, IEM-3500-8S=, IEM-3500-16T=, IEM-3500-6T2S= or IEM-3500-14T2S=, or none. Modules are separate orderable items, and their power draw is counted against the host.
- SD card: Add SD-IE-16GB= if configuration backup or switch replacement from card is wanted. The card is optional and not fitted by default.
- Software tier: Network Essentials ships as ordered; IE3500-NW-A= (perpetual) upgrades to Network Advantage later, and IE3500-DNA-E or IE3500-DNA-A adds a Catalyst Center subscription. DNA Advantage works only with the Network Advantage license, so the tiers must match.
- Uplink optics: Select GE SFP modules, with industrial-grade parts such as GLC-FE-100FX-RGD= or GLC-FE-100LX-RGD= for 100M links. Commercial or non-industrial SFPs force a lower operating temperature.
- Mounting: Choose DIN rail mounting; STK-RACK-DINRAIL= is the 19-inch DIN rail mount kit. The rack mount kit is a separate item.
