Abstract

A control device for a master/slave signal of storing device for a computer mobile rack comprises an inner rack and an extended device. The inner rack is a semi-enclosed rack, an inner rack connector is disposed at the rear plate thereof to engage with a fixing connector preset at a containing frame on the computer system unit and with the storing device to constitute a circuit and a signal connections. The extended device has two ends and an end thereof is provided with a joining terminal and the other end thereof is provided with an adjustable terminal. The adjustable terminal is possible to allow at least a jumper being detachably inserted therein. Once the storing device is fixed to the inner rack, the terminal seat at the rear side of the storing device can be inserted by and engage with the joining terminal on the extended device. Therefore, the signal can be extended via the adjustable terminal. The terminal seat is disposed at the rear plate or the front plate of the inner rack and at least a jumper may detachably engage with pins in the adjustable terminal optionally to adjust the master/slave signal of the storing device quickly.

Claims

1. A computer rack having a master/slave storing device and a control device for controlling the master/slave function of the storing device and comprising:

a) an inner rack having a rear portion with a rear plate;

b) a storing device mounted in the inner rack, the storing device including a rear terminal;

c) a connector mounted on the inner rack so as to be accessible from exteriorly of the inner rack, the connector connected to the rear terminal of the storing device; and

,

d) an extending device including a joining terminal connected to the rear terminal of the storing device and an adjustable terminal mounted on the connector so as to be accessible from exteriorly of the inner rack, whereby the adjustable terminal controls the master/slave function of the storing device.

2. The computer rack of claim 1 further comprising a jumper is removably connectable with the adjustable terminal so as to control the master/slave function of the storing device.

3. The computer rack of claim 1 wherein the connector is mounted on the rear portion of the inner rack.

4. The computer rack of claim 1 wherein the adjustable terminal comprises a switch.
