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
•Removing a Failed Power Supply on page 3

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.
