Remove and Replace the Power Supply
Overview
Every i6 library module that contains tape drives
If the library has two power supplies, one power supply can be replaced with power applied to the other power supply, but doing so will produce a RAS ticket.
Additional Information
- Library modules that contain both an iBlade and tape drives must have two power supplies installed.
- The power supply is highly efficient, rated at 80 PLUS®, a performance specification that requires an 80% or higher energy efficiency at 10, 20, 50 and 100% of rated load with a true power factor of 0.9 or greater.
- The power supply connects to an outside power source and converts the input power to the AC and DC voltages used by the library components.

LEDs |
Power Supply LEDs provide you with visual information that let you know the power supply is working correctly. Normal indications:
If the Fault LED is solid blue, or if the other two LEDs are off, you should check for RAS tickets to learn how to resolve the problem. |
2 | Handle | Used to remove and install the power supply. |
3 | Thumbscrews | Used to secure the power supply to the chassis. |
Before You Begin
Before you begin the removal procedure, take a snapshot of the library and save your library configuration. These will be used to restore your library if any issues occur after the removal and replacement procedure.
Your library has many configurable items, such as tape drive IDs, partitions, user accounts, Import/Export (I/E) slots, and cleaning slots. The Save/Restore window allows you to save your library's configuration and then restore the library’s firmware and configurable items to a previous state in the event of a hardware failure or firmware upgrade.
Restore a Configuration on the same Library
Before you restore a library configuration, review the following:
- If you have Logical System Addressing (LSA) enabled on the library, the saved configuration is specific to that library only. Do not attempt to clone the configuration to a different library.
- The library must have all the proper licenses installed before restoring a configuration.
Restore a Configuration on a new Library
Before you restore a library configuration, review the following:
- If you have LSA enabled and want to clone the configuration to a new library, you must first disable LSA and save the configuration (see Library Settings).
- If you want to clone a saved configuration to another library, you should only use the saved configuration upon initial installation of a new library. Once a the cloned configuration is on a new library, you should save a configuration specific to that new library.
- If you are cloning a saved configuration to a new library, the new library must have the same minimum license configuration as the library where the saved configuration came from.
- If you are cloning a saved configuration to a new library, the new library must have at least the same minimum module configuration. For example, if the library the saved configuration came from has 4 modules, the new library must have a least 4 or more modules.

Restore Configuration |
Restores library to the selected configuration. After the restore, the library will automatically reboot. |
Select the radio button. |
Restore Filename | Allows you to select the name of the library configuration file you want to restore. | Click the Browse button and navigate to the configuration file you want to use. Click Apply to begin restoring the library configuration. |
Save Configuration | Saves the current library configuration. | Select the radio button. Click Apply. The library configuration file is downloaded. You can then use the file locally or email it. |
Click Close to exit the window.
The Library Snapshot feature captures detailed information about the entire library in a single ASCII file that can be e-mailed to technical support personnel. The information consists of configuration data, status information, and trace logs for library components. Trace logs collect problem data and provide support personnel with vital library information for troubleshooting and solving problems.
You can e-mail the snapshot file from the WebGUI. You can also download the snapshot file to your computer. However, you cannot print snapshot files directly from the Web client. Depending on the library configuration and your connection speed, saving the snapshot file could take several minutes. The resulting file size can be large. In some cases, your firewall file-size limitations could prohibit you from emailing the file.

Item Description Action Snapshot Type Select a Standard or Extended library snapshot. - Select Standard to collect the library data documented above.
- Select Extended to collect Standard library data, plus additional log history data and all collected tape drive data dumps.
Note: Extended snapshots cannot be send via email.
Save Allows you to save the snapshot file to a computer. Select the Save radio button and click Apply. Send This feature allows you send the snapshot to any email address you want. Select the Send radio button. E-mail Address This field allows you to enter in an email address. Enter the desired email address and click the icon. Repeat this until all intended email recipients are displayed in the box below the E-mail Address field. When finished, click Apply to send the snapshot. - Click Close to exit the window.
Remove Power Supply
There are several ways to identify the failed power supply:
In the WebGUI, you can refer to the RAS ticket for the power supply failure under Status > RAS Tickets.
You can also select the Status WebGUI option and review the system Power Consumption status. The power supply to be replaced will have a status of Failed.
Use the LEDs on the power supply to identify the failed unit. In a failed power supply, the Fault LED is illuminated, and the AC OK and/or the DC OK LED is off.
This video shows the power supply replacement procedure for a Scalar i6. The overall procedure is the same for the Scalar i3.
-
Power the library down. If you have redundant power you don’t have to shut the library down. However, replacing a power supply with power applied will generate a RAS ticket.
In the WebGUI, select Shut Down from the admin menu on the Menu Bar.
- Unplug the power cord from the power supply.
- Loosen the thumbscrew.
- Pull the handle and slide the power supply out of the module.
Replace Power Supply
This video shows the power supply replacement procedure for a Scalar i6. The overall procedure is the same for the Scalar i3.
- Slide the power supply into its slot until the front bezel is sitting flush against the back of the module.
- Tighten the thumbscrew until finger tight.
- Plug the power cord into the power supply. The library will begin start up operations.
