Power Supply Replacement
Instructions
These instructions describe how to replace a power supply in your Spectra
T120 library.
PREPARE FOR THE PROCEDURE
Ensuring ESD Protection
The repair environment for the library must be free of conditions that
could cause electrostatic discharge (ESD). To protect the library from ESD,
follow these procedures:
 Place a static protection mat on the work surface used during this
procedure. Use a 1-megaohm resistor to ground the static protection mat.
Wear a static protection wrist band whenever you handle the
component when it is not in its antistatic bag. Connect this wrist band
to the static protection mat or to other suitable ESD grounding.
Keep all components in antistatic bags when not in use.
Gathering Tools and Supplies
You need the following tools and supplies to perform this procedure:
A #3 or #2 Phillips Screwdriver
Note: A #3 Phillips screwdriver is the proper
tool, but a #2 Phillips screwdriver will also work.
A Replacement 5V/12V Power Supply
Note: After removing the new power supply
from its packaging, use the packaging to return
the old power supply to Spectra Logic.

Following Backup Guidelines
Stop Backups If the library is configured with a single power supply, the
library has lost power and will not power back on until the power supply
has been replaced.
Continue Backups If the library is configured with two power supplies,
the library is still operational with a single power supply functioning;
backup operations can continue while you replace the failing component.
Locating and Preparing the Malfunctioning Power Supply
One Power Supply Installed If you only have one power supply installed,
flip the power switch to the “off” position and disconnect the power cord,
then proceed to Replace the Power Supply on page 5.
Two Power Supplies Installed If you have two power supplies installed
and AC input to both, follow these steps to determine which power supply
is malfunctioning:
1. Power the library on, then access the back of the library.
2. Check the power supply LEDs, as shown below.
3. Locate the power supply on which the DC Output (top) LED is off.
4.
Flip the power switch to the “off” position and disconnect the power cord.
LED lights and meaning:
Solid green — the power supply is operating normally.
Off (unlit) — the power supply is malfunctioning.

REPLACE THE POWER SUPPLY
1. Use a #3 or #2 Phillips screwdriver to loosen the screw in the upper
right corner of the power supply that you are removing.
2. Pull outward on the handle and gently remove the power supply from
the library.
3. Set the old power supply aside for return to Spectra Logic.
4. Place the new power supply into the empty slot and push it in gently.
5. Tighten the screw using a #3 or #2 Phillips screwdriver.
6. Reattach the power cord and flip the power switch to the “on” position.
7. If necessary, use your backup software to restart any backups that were
stopped when the power supply malfunctioned.
You are now ready to package the component for return to Spectra Logic.

RETURN THE COMPONENT
Return Guidelines
Unless Spectra Logic Technical Support informs you otherwise, return the
defective component to Spectra Logic following the guidelines in the
Return Procedures section below. If Spectra Logic Technical Support
informs you that the component does not need to be returned, dispose of it
in a manner appropriate for your company guidelines.
Return Procedures
After you complete the replacement procedure, return the defective
component using ALL the packaging that the replacement component
arrived in (including any anti-static bags or foam inserts).
Use the return label and instructions that were included with the
replacement component when preparing to ship the replacement part. If
you cannot locate these, contact Spectra Logic for another copy (see
Contacting Spectra Logic on page 2). The return label and RMA printed on
it are used to associate the returned part with your account. To avoid being
invoiced for failure to return the part, do not ship the part back without the
RMA return label.
Caution
Severe damage can occur if the component is not packaged correctly, and you may
be invoiced if it is received with damage due to improper or insufficient packaging.
