6 Adding Power Supplies and Tape Drives

The tape drives and power supplies are located at the back of the library (see Figure 6-1). Each module in the library has space for two tape drives and two power supplies. You can add tape drives and power supplies as your needs grow.

The power supply and tape drive can be added while the library is powered-on. However, you must restart the library for it to recognize and account for the tape drive.

The instructions in this chapter have you momentarily remove the power supply or drive filler and then immediately insert the new power supply or tape drive in the open slot.

Warning:

Do not operate the library with open tape drive or power supply slots.

Power Supply

Two actions are involved to add a power supply (see Figure 6-2) to a library module: 1) removal of the power supply filler and 2) installation of the power supply. No tools are required to perform these tasks.

To Remove the Power Supply Filler

Hook your finger in the hole of the power supply filler (see Figure 6-1).
Pull the filler out of the power supply slot and set it aside.

To Install an Additional Power Supply

Remove the power supply from the shipping carton.
Grasp the power supply by the handle with one hand and support the bottom of the supply with your other hand.
Guide the power supply into the power supply slot.
Make sure the power supply is latched in place.
Connect a power cord to the power supply receptacle and a receptacle on the rack power strip.
Gather cord slack to the outside of the library then secure with the hook and loop strap(s).

Tape Drive Tray

Two actions are involved to add a tape drive tray (see Figure 6-3) to a library module: 1) removal of the tape drive filler and 2) installation of the tape drive tray. No tools are required to perform these tasks.

Note:

You must restart the library to recognize and account for the installation of a tape drive tray. You might need to coordinate the restart around backup windows and other activities.

To Remove the Tape Drive Filler

Loosen the thumbscrews on both sides of the tape drive filler (see Figure 6-1).
Grasp the thumbscrews and pull the filler toward you.
Remove the filler from the drive slot and set it aside.

To Install an Additional Tape Drive Tray

Caution:

Equipment damage. Do not touch the circuit card or static sensitive components. The circuit card is located on the right side of the drive tray (see Figure 6-3).

Task 1 Install the Tape Drive Tray

Follow accepted practices to prevent ESD.
Remove the drive tray from the shipping carton.

Note:
Handle the drive tray by the rear corners (close to the thumbscrews) and the bottom of the tray. Avoid contact with the top cover of the actual tape drive.
Grasp the rear corners of the drive tray and guide the front of the drive tray into the library drive slot.
Push the drive tray completely into the drive slot.

The LEDs activate at the rear of the drive tray if the library is powered on.
Tighten the thumbscrews firmly on each side of the drive tray to make sure there is no tray movement in any direction.
Connect the interface cable to the port on the left side of the drive.

Task 2 Restart the Library

Quiesce the host application(s) to prevent disruption of active storage operations.
Restart the Library by one of the following methods to enable the library to recognize and account for the new tape drive.
1. Push the library power button and tap Restart Library on the touch screen.
2. Click the power button in the SL150 remote interface and click Restart Library in the dialog box.
  
  The tape drive appears in the library listing of available drives after completion of the restart.
Confirm that the library recognizes and accounts for the drive (Drives area of the SL150 remote interface).

It can take some time for the drive to be recognized by the library and for the LEDs to indicate the drive is operational.
Make sure the drive port is enabled (view the Drive Properties and change drive settings if appropriate).

Verify the firmware level of the added drive is consistent with that of other installed tape drives (see Appendix B, "Drive Firmware").

Note:

You might need to run application commands to ensure that the library and drive application are synchronized after installing a tape drive. Refer to your host tape application documentation for guidance.
