Installing a power supply

A power supply is required to provide current to the disc drive. Several vendors offer power supplies that meet the disc drive’s power requirements. Ensure that the power supply you select meets these requirements as specified in Table 3.

Setting the voltage range

Caution. Most power supplies will be damaged if the voltage select is set for the low range (100–120 VAC) and a voltage in the high range (208– 240 VAC) is applied.

1.Ensure that the AC power cable is disconnected from the power supply.

2.Refer to the power supply documentation, or contact the supplier for instructions.

Mounting the power supply

1.Mount the power supply in the desired location.

2.Connect a ground strap between the power supply and the cabinet ground.

3.Attach the AC power cord to the power supply connector. Do not connect the power cord to site power until directed.
