Replace an i6H Expansion Module (EM) Chassis

This procedure replaces an existing Expansion Module (EM) chassis with a new EM chassis.

Tool Requirements

Removing an i6H library module requires the following tools:

Before You Begin

Before you begin the removal procedure, take a snapshot of the library and save your library configuration.

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.

Item Description Action
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.

Remove the Expansion Module (EM) Chassis

To remove the robot, you must remove the Service Tray from the Control Service Module (CSM).

  1. On the front of the CSM, open the left and right Service Tray Access Doors.

    Item Name Description

    1

    		Service Tray Access Doors Access to the override button and paddle that controls the buttons and paddles of the Service Tray receive and capture features.

  2. Verify that blue paddles in both the left and right service tray access panels are in the Captured position.

    If both paddles are not in the Captured position, go to step 3.

    If both paddles are in the Captured position, go to step 4.

  3. Depress the Service Override button while rotating the paddle to the Captured position. Repeat this step in the other Service Tray Access panel.

    Caution: If the paddle does turn freely by hand is should not be forced. This typically implies the robot is not in a proper position. Forcing the paddle can cause damage to the Service Tray.

    Note: If the paddle does not rotate to the Captured position, the robot is not fully seated on the Catch Shelves.

  4. Remove the Service Tray. To unlock the Service Tray from the CSM, press the Interlock button. With the Interlock button pushed, lift the Service Tray Release Latch up and rotate it 90 degrees counterclockwise.

    Item Name Description
    1 Interlock Button Push the Interlock button while rotating the Service Tray Release Latch.
    2 Service Tray Release Latch Rotate 90 degrees counterclockwise to the Unlocked postiion.

  5. Pull on the Service Tray Release Latch to remove the Service Tray from the CSM. When handling the Service Tray, use the blue handles and keep the tray level to avoid any damage to the tray.

Handling the Robot Service Tray

To properly handle the Service Tray outside of the library, Quantum recommends the following:

  1. Place the Robot Shipping Restraint on the Robot Picker when handling the Service Tray. This will prevent excessive movement and damage to the Robot Picker.

    Note: When restrained, the robot picker must aligned over the reach assembly in the location below.

  2. Use the blue handles on the Service Tray when handling the Service Tray.

    Item Name Description
    1 Service Tray Handles Use handles when lifting and moving Service Tray.

  3. Keep the Service Tray horizontally flat. Handling the Service Tray vertically or at an angle may cause damage to tray components.

Important Information

  • When the Service Tray is out of the library, do not touch the toothed belt that drives the robot picker mechanism. The belt is under low spring tension and is not designed to withstand direct intentional or unintentional handling.

  • When the Service Tray is out of the library, do not touch robot ribbon cable . The cable tether and orange cable guide are not designed to withstand direct intentional or unintentional handling. If the cable tether gets folded, creased, or bent in manner that is not part of normal robotic operation, the cable can take a permanent set that can later interfere with automatic robot operation.

1 Robot Picker Belt
2 Robot Ribbon Cable

Important Information

Follow Steps 2 - 9 below for each module before removing the next module.

Mark or take a picture of all the magazines, drives, and cable in the module so you can correctly return everything to where it belongs.

If the module you are removing has drives and power supplies, do the following:

  1. Disconnect the power cables from power supplies.
  2. Disconnect the SAS or Fibre channel cables from the drives.

You will need to remove the components from each module that will need to be removed from the library to access the module that will be replaced.

There are three different type of module configurations. Follow the module component instructions below.

Note: The library configuration below is an example. The library EM and drive configuration is different for each hyperscaler customer.
