INTRODUCTION

The JMB321-SW4 1-to-4 SATA2 Expander Switch is designed to provide a high performance link between a single SATA2 host port and 4 SATA device ports. It connects the host upstream port to one of the 4 downstream SATA devices (expand 1 port into 4 ports that can be used at the same time). Each drive can be added or removed by simply pressing the corresponding push button switch.

With its Power Switching circuits and hot-plug&hot-swap feature, the JMB321-SW4 can add or remove each drive without turning off the system power. It allows from 1 to 4 drives to be accessed simultaneously. It powers the active devices and cut off the powers of the inactive devices. This will reduce the power consumption and make sure those devices are true off line to prevent from any accidental erasing data by virus or application software.

The JMB321-SW4 provides a keylock switch to prevent from any unauthorized changing the settings. It helps home of school users to manage the devices easily.

The JMB321-SW4 is designed for optimum performance and expandability and security. It is an ideal upgrade solution to support SATA and SATA2 devices for the rapidly changing data to preserve users investment in the SATA interface.
