Switch UMD-S326A2O030


New energy saving design, for the government, enterprises and institutions to provide a simple, economic, energy saving, high-performance gigabit network solutions.


Non-blocking forward at a high speed

UMD-S326A2O030 switches all port's ability to provide wire-speed switching on the second floor, ensure all ports nonblocking packet forwarding.

Support MDI/MDIX Function

Plug-and-play design, automatically identify the network cable types( straight forward cable or cross-over cable) and communicate normally.

Support Auto-negotiation of port rate

Support 10/100/1000M multirate terminal, automatically identify the terminal network card rate and duplex mode, reducing maintenance requirements;

The LED indicator can dynamically show the different operation rate.

Carrier-class High-reliable Power Protection

Adopt carrier-class switching power supply, which supports functions to prevent against lightning, overpressure and surging. The device can work normally in bad natural wether and instable voltage environment, suitable for 100~265V voltage.

Innovative Energy Saving Design, the leader of low-carbon communication

Support IEEE 802.3az(Energy Efficient Ethernet ), port energy detection, CPU variable-frequency and device hibernate technology, greatly reducing energy consumption and noise without compromising performance and stability.
