Cisco IE-3100-3P1U2S-E | Catalyst IE3100 Rugged 4-Port Industrial Switch, 120W PoE, 2x 1G SFP

Q: What is the difference between the PoE+ and 4PPoE ports on this switch?
A: Ports 1-3 support standard PoE+ (802.3at) delivering up to 30W per port, while Port 4 supports 4PPoE/UPoE (802.3bt) delivering up to 90W per port. This higher-power port is ideal for devices like PTZ cameras, high-power wireless access points, or industrial sensors requiring more than 30W.

Q: Can this switch operate in outdoor or harsh industrial environments?
A: Yes, the IE-3100-3P1U2S-E is specifically designed for harsh environments with an operating temperature range of -40°C to 75°C, fanless operation, DIN-rail mounting, and IP30-rated enclosure. It's ideal for manufacturing plants, substations, transportation systems, and outdoor cabinets where space is limited.

Q: Does this model support Layer 3 routing features?
A: No, the IE-3100-3P1U2S-E comes with Network Essentials licensing, which provides Layer 2 switching and static routing capabilities. For advanced Layer 3 features, consider the IE3300 or IE3400 series with Network Advantage licensing.

Q: What industrial protocols does this switch support?
A: The IE3100 series supports key industrial automation protocols including EtherNet/IP (CIP), Modbus, PROFINET, and IEEE 1588v2 Precision Timing Protocol (PTP), making it compatible with PLCs, SCADA systems, and other industrial control devices.

Q: Is the PoE budget adjustable based on input voltage?
A: Yes, the switch automatically adjusts the PoE power budget based on input voltage. With input voltage of 52.5V or greater, it supports the full 120W PoE budget. At lower voltages, the PoE budget is automatically reduced to ensure stable operation.
