Installing or Replacing a Power Supply
These instructions describe how to install a power supply in a T50e library.
Ensure that the work area is free from conditions that could cause electrostatic
discharge (ESD). Discharge static electricity from your body by touching a known
grounded surface, such as a computer’s metal chassis.
Gathering Tools and Supplies
You need the following tools and supplies to install the power supply:
A new power supply kit from Spectra Logic
A power cable (included in the kit)
A #2 Phillips screwdriver
Continuing Backups
If your library has:
Only one power supply module installed—backups are interrupted when the power
supply malfunctions and cannot resume until the power supply is replaced. In this
case, you must power-off the library as the first step in the procedure. See
Replacing an Existing Power Supply
Two power supply modules installed for N+1 redundancy and one power supply
fails or is removed—backups can continue while you replace the malfunctioning
power supply. See Installing a Redundant Power Supply below.

Installing a Redundant Power Supply
Note: Redundant power supplies are “hot pluggable” (you do not need to
power off the library to perform this procedure).
Follow these steps to install the power supply.
