IE-3505-8P3S-E Description

The IE-3505-8P3S-E is a Cisco Catalyst IE3500 Rugged Series advanced modular industrial switch for DIN-rail control cabinets that power cameras and sensors. The switch has eight Gigabit PoE/PoE+ copper ports, three 1G/100M SFP uplinks and a 240W base PoE budget, which reaches 480W with IE3500 expansion modules. PoE needs a DC input of at least 46V, PoE+ needs 52V or more, and the switch ships without a power supply.

Key Features

Eight PoE/PoE+ Copper Ports

All eight Gigabit copper ports supply PoE or PoE+, so cameras, access points and panels connect without separate injectors.

Three SFP Uplinks

Three 1G/100M SFP ports take fiber or industrial-grade FE and GE optics for runs between cabinets.

240W Base PoE, 480W With Modules

The base switch supplies 240W of PoE, and attaching IE3500 expansion modules lifts the total budget to 480W.

PRP, HSR And DLR Redundancy

IE3505 variants add Parallel Redundancy Protocol, High-availability Seamless Redundancy and Device Level Ring for zero-delay failover.

Dual DC Power Inputs

Two DC inputs from 12V to 54V keep the switch running if one feed fails, and PoE+ operation needs at least 52V.

Modular DIN-Rail Chassis

A DIN-rail body with a no-fan design takes expansion modules up to 27 total ports and works from -40 to +70°C with 40 LFM airflow.

Application Scenarios

Camera Cabinet On A Plant Floor

In a DIN-rail cabinet on a production line, the switch powers IP cameras and operator panels from its PoE/PoE+ ports and sends their traffic upstream over SFP fiber.

Redundant Ring In A Substation Yard

A control building can place the switch in a ring that needs seamless failover, since PRP, HSR and DLR are supported on IE3505 variants only.

Port Growth At A Pumping Station

A water site that adds sensors and wireless access points can attach IEM-3500 expansion modules and draw up to 480W of total PoE from the same cabinet.

IE-3505-8P3S-E and IE-3500-8P3S-E share eight PoE/PoE+ ports, three 100/1000 SFP uplinks and a 240 W base PoE budget, but IE-3505-8P3S-E reaches 480 W with an IE3500 expansion module against 360 W, and only the IE3505 line supports PRP, HSR and DLR. Rings that need seamless redundancy, or expansion modules that push PoE past 360 W, call for IE-3505-8P3S-E. Powered devices that need 4PPoE or 10G/1G SFP+ uplinks move to IE-3500-8U3X-E, which holds 480 W with or without expansion. This PID carries Network Essentials; Network Advantage on the same hardware is IE-3505-8P3S-A, or the IE3500-NW-A= upgrade license.

Ordering Checklist

  • Power supply: Pick a PoE-capable supply: PWR-IE65W-PC-AC=, PWR-IE170W-PC-AC=, PWR-IE240W-PCAC-L= or PWR-IE480W-PCAC-L=. The 50W PWR-IE50W-AC= family does not support PoE; no supply ships with the switch, and it must cover the switch, expansion modules and PoE load.
  • Dual power inputs: With two supplies on DC-A and DC-B that both support PoE, the system PoE budget follows the smaller one. A small second supply caps the budget below the larger one.
  • Expansion modules: Choose IEM-3500-8P=, IEM-3500-16P=, IEM-3500-4MU=, IEM-3500-8T=, IEM-3500-8S=, IEM-3500-16T=, IEM-3500-6T2S= or IEM-3500-14T2S=. Each module adds 6W to 22W of draw, and IEM-3500-4MU= does not support HSR, PRP or DLR, so it cannot join a PRP, HSR or DLR design.
  • SD card: Add SD-IE-16GB= for the optional SD slot. The card does not ship with the switch by default.
  • License and subscription: Network Essentials ships with this PID; IE3500-NW-A= adds Network Advantage, and IE3500-DNA-A subscriptions require Network Advantage. A DNA Advantage subscription ordered on a Network Essentials switch cannot be used.
  • SFP optics: Select industrial-grade SFPs such as GLC-FE-100FX-RGD= or GLC-FE-100LX-RGD= for the 100/1000 SFP uplinks. EXT or COM temperature SFPs force the switch operating temperature to be derated.
