High-Performance Cisco® Switches for Mobile and Stationary Networks in Harsh Environments
The OPTOKON® LMSW-E33 series is a line of rugged Layer 2/3 Gigabit Ethernet managed PoE switches developed using Cisco® Embedded Service Switch (ESS) or Cisco® IE technologies.
The switches ensure secure transmission of data, voice, and video between stationary and mobile network nodes, providing stable operation even under extreme conditions. With a compact and robust housing, a wide operating temperature range, and PoE support, the LMSW-E33 series is ideal for tactical, transportation, industrial, and field-deployed applications.
The optical ports are based on the HMA Expanded Beam format, providing resistance to dust, moisture, and mechanical impact without signal quality degradation.
Main Advantages
- Rugged design: resistant to shock, dust, vibration, and temperature fluctuations.
- Cisco IOS® Software: supports Network Essentials (L2) and Network Advantage (L3).
- Flexible connectivity: models with 1G or 10G ports, optical (HMA) or copper (RJ-45 / D38999).
- Full management capabilities: Web UI, CLI, SNMP, DHCP, SPAN, syslog, SmartPort.
- PoE support: power for connected devices (up to 360 W budget).
- Universal power input: 20–40 V DC, compatible with 24 V DC systems.
- Wide temperature range: –40 °C to +70 °C.
- Flexible installation: rack-mount (19") or standalone use.
