Cisco IE-3505-8P3S-A | Catalyst IE3500 Rugged 8-Port Gigabit PoE+ Switch, 240W, 3x 1G SFP

Q: What environments is the IE-3505-8P3S-A designed for?
A: This switch is built for harsh industrial OT edge environments with IP30 protection, fanless operation, and an extended temperature range of -40°C to +75°C. It's ideal for manufacturing plants, utility substations, transportation systems, and other industrial automation applications.

Q: Can I expand the port capacity of this switch?
A: Yes, the IE-3505-8P3S-A supports modular expansion up to 27 total ports using IEM expansion modules. These modules can add copper ports, fiber ports, or additional PoE ports depending on your specific connectivity requirements.

Q: What is included with the Network Advantage license?
A: The Network Advantage license provides advanced Layer 2 and Layer 3 routing features including OSPF, BGP-EVPN, and Software-Defined Access capabilities. It also includes a 3-year limited-term subscription to Cisco Cyber Vision for OT asset visibility and Cisco Secure Equipment Access for zero-trust remote access at no additional cost.

Q: How do I power this switch and connected PoE devices?
A: The switch requires an external DIN-rail power supply (ordered separately) with dual DC input support ranging from 12-54 VDC. The base PoE budget is 240W, which can be expanded to 480W with an optional PoE expansion module to support more power-intensive devices.

Q: What industrial protocols does this switch support?
A: The IE-3505-8P3S-A supports industrial resilience protocols including Media Redundancy Protocol (MRP), Resilient Ethernet Protocol (REP), Device Level Ring (DLR), Parallel Redundancy Protocol (PRP), and High-availability Seamless Redundancy (HSR). It also features TSN frame-preemption for time-sensitive control applications.
