SEL-2741

Managed RSTP or Managed OT SDN Switch

This 24-port Gigabit switch is SEL’s next-generation network platform, combining the proven reliability of traditional managed switches with the flexibility of future-oriented Software-Defined Networking (SDN) technology.
It is specifically engineered to serve as a critical backbone for IEC 61850 compliant protection networks, engineering access, SCADA, and Process Control Systems (PCS) within the demanding environments of the energy and utility industries.

Key Features

Full Gigabit Support

All 24 ports support high-speed data transmission at either 100 Mbps or 1 Gbps.
Hardware-Accelerated Failover

Equipped with a hardware-optimized recovery mechanism to ensure the near-instantaneous failover required for mission-critical control signal applications.
Extreme Environmental Durability * Wide Temperature Range

Operates reliably from -40°C to +85°C.
Fanless Design: Eliminates potential failure points caused by mechanical wear or dust ingress.
Compliance: Fully meets IEEE 1613 and IEC 61850-3 standards for substation environments.
Dual Power Supplies

Features integrated dual power supply options, allowing for simultaneous connection to primary and redundant power sources to maximize uptime.
PTP Transparent Clock

Guarantees precise time synchronization across the network by compensating for packet "residence time" as data passes through the switch.

Flexible Port Configuration

Customizable port layouts allow users to order combinations of 100/1000BASE-T RJ45 ports and SFP (Small Form-Factor Pluggable) ports in increments of four.
Traffic LED Indicators

The front-panel LEDs provide intuitive, color-coded status updates for alarms, link activity, traffic flow, and overall switch operation.
Customizable Nameplate Labeling

Includes a protected insertion window on the front panel, enabling users to clearly label the device with hostnames, IP addresses, or specific functions.
Versatile Mounting Options

Supports multiple installation methods to fit various environments, including rack-mount, panel-mount, and surface-mount configurations.
