5. Memory: 4 GB DRAM for robust performance under heavy traffic loads.

Industrial & Environmental

1. Form Factor: Fixed system, compact DIN-Rail mountable design.
2. Cooling: Fanless, convection-cooled (no moving parts for increased MTBF).
3. Operating Temp: -40° to +75°C (-40° to +167°F) with cold start at -40°C.
4. Ingress Protection: IP30 rated ruggedized housing.
5. Compliance: Meets industrial standards for automation, ITS (Intelligent Transport Systems), and substation environments (IEC 61850-3, IEEE 1613).

Software & Intelligence

1. Software License: Network Essentials (Foundational L3 functionality).
2. Security: Support for 802.1X, Port Security, TrustSec SGT, and Layer-2 Network Address Translation (L2NAT).
3. Management: WebUI (modern browser-based GUI), CLI, SNMP, and Cisco DNA Center (Catalyst Center) compatible.
4. Time Synchronization: Support for IEEE 1588v2 Precision Time Protocol (PTP) with power and manufacturing profiles.

Power & Physical

1. Power Input: Dual DC inputs (12V to 48V nominal) for power redundancy.
2. Power Consumption: Approximately 36.7W (efficient, low-heat design).
3. Dimensions: 5.00 x 4.30 x 5.08 inches (12.70 x 10.92 x 12.90 cm).
4. Weight: ~2.8 lbs (1.27 kg).

Technical Note: The "IE-3105" variant is specifically noted for including an enhanced feature set over the standard IE3100 series, including support for Layer-2 NAT, which is critical for connecting machines with conflicting IP addresses in industrial subnets.
