### 4. Functionality

The IES‑150B functions as an unmanaged Layer 2 Ethernet switch, automatically forwarding Ethernet frames between connected devices without user configuration. It uses store‑and‑forward packet processing to ensure data integrity and supports both full‑duplex and half‑duplex communication modes.

Typical Use Cases:
- Connecting Ethernet I/O modules, PLCs, and HMIs in industrial automation systems.
- Linking IP cameras and network video recorders in surveillance networks.
- Expanding Ethernet connectivity in transportation, energy, or utility control systems.
- Integrating multiple unmanaged switches in distributed control networks.

Compatibility:
The switch is fully compatible with standard Ethernet devices supporting IEEE 802.3/802.3u/802.3x protocols. It can interoperate with managed or unmanaged switches, routers, and industrial controllers from various vendors.

Operation:
Once powered, the switch automatically detects link speed and duplex mode for each port. Data packets are buffered and forwarded using store‑and‑forward logic, ensuring error‑checked transmission. Flow control prevents packet loss under heavy traffic conditions.
