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 the Power Supply
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.

Installing or Replacing a Power Supply

1. Prepare the library—Access the back of the library.
a. Remove the screws securing the cover plate using a #2 Phillips screwdriver.
b. Set the plate and screws aside.
2. Install the power supply—Slide the new power supply straight into the opening.
a. Gently push the power supply in until it fully seats itself in the library.
b. Secure the power supply by tightening the finger screws.
c. Connect the power cord.
Note: Connect each of the library’s AC inputs to a separate circuit. Using
separate circuits allows for failover in the event of a power failure
in one of the circuits. The failover feature requires the N+1 power
redundancy option.
Your power supply is installed and you can resume operation.

Replacing an Existing Power Supply
Follow these steps to replace the single power supply (see Figure 1 and Figure 4).
1. Prepare the library—Ensure that the library is not performing a task by observing
that the BlueScale User Interface on the front panel is idle.
a. Press the front panel power button. The power-off sequence takes
approximately two minutes while the library allows applications to shut down
gracefully.
b. Access the back of the library and disconnect the power cord.
2. Remove the power supply—Loosen the finger screws by hand or with a
#2 Phillips screwdriver and slide the power supply straight out of the library.
Note: After removing the new power supply from its packaging, keep the
packaging to return the old power supply to Spectra Logic.

3. Install the replacement power supply—Slide the new power supply straight into
the library.
a. Secure the power supply by tightening the finger screws.
b. Connect one end of the power cord to the power supply and the other end to an
outlet.
c. Press and hold the front panel power button for two to three seconds to power
on the library. Wait while the library completes its power-on sequence, which
takes from six to nine minutes depending on your library configuration.
4. Package the power supply module and ship it to Spectra Logic as described in
Returning Components below.
Restarting Backups
If necessary, use your backup software to restart any backups that were stopped when
the power supply malfunctioned.
Returning Components
After you complete the replacement procedure, return the malfunctioning power
supply (component) to Spectra Logic.
Packaging a Component for Shipment
Note: Use the packaging from the replacement component to pack the
component you are returning. The packaging may look somewhat
different from that shown in this section.
1. Place the component inside the anti-static bag.

2. Fold the bag snugly around the component and tape it closed (see Figure 5).
3. Place the bottom air cushion, plastic side up, in the shipping box.
4. Place the wrapped component in the center of the bottom air cushion (see
Figure 6).
Note: The air cushions for the power supply are slightly different in
appearance, but function the same way.
5. Place the top air cushion, plastic side down, over the component (see Figure 7).
When properly installed, the two air cushions suspend the component securely in
the center of the box. These illustrations show a generic component for reference.
6. Close the box and securely tape it shut.
Figure 5 Wrap the component in an anti-static
bag (generic component shown).
Figure 6 Place the component on the
bottom air cushion. Figure 7 Place the top air cushion over the component.

Shipping RMA Returns
Caution: You must package the component in the box provided by
Spectra Logic, making sure to use all of the packing materials
provided to prevent damage during shipment.
Failure to properly package the component may result in
damage to the component. If a component is damaged in
shipping due to improper packing, the warranty on the
component is void.
1. Before you ship a component back to Spectra Logic, obtain a Return Materials
Authorization (RMA) number from a SpectraGuard Technical Support
representative. Spectra Logic needs this number to identify the part on its arrival.
2. Write the RMA number on the shipping label. If you fail to include the RMA number
on the label, the package will be returned to you. If you do not know your RMA
number, contact SpectraGuard Technical Support.
3. Follow the steps in the table below that are appropriate for your location.
