Power Supply Replacement

The Scalar Linear Tape File System (LTFS) Appliance is powered by two

redundant, “hot-swappable” power supplies located in the back of the unit.

Once the failed power supply is identified, the power supply can be easily

replaced and the Scalar LTFS Appliance returned to normal operation. Always

replace faulty power supplies to ensure redundant operation.

To replace the power supply, refer to the following sections:

•Preparing to Replace a Power Supply on page 2

2When disconnecting the power cable, remove the cable from the strap.

3Remove the power supply cable from the failed power supply.

4Press the release latch and use the power supply handle to help remove the

power supply from the Scalar LTFS Appliance.

3To ensure that the power supply is working properly, check the power

supply’s LED indicators.

A green light indicates that a valid AC source is connected to the power

supply, and that the power supply is operational. When Scalar LTFS

Appliance is on, a green light also indicates that the power supply is

providing DC power to the appliance.

4When connecting the power cable, secure the cable with the strap.
