Please remove the device located in:
    Location: U0.1-P1-I4/Z1-A8
```
Attention:
- Attach a wrist strap to an unpainted metal surface of your hardware to prevent electrostatic discharge (ESD) from damaging your hardware.
- When using a wrist strap, follow all electrical safety procedures. A wrist strap is for static control. It does not increase or decrease your risk of receiving electric shock when using or working on electrical equipment.
- If you do not have a wrist strap, just prior to removing the product from ESD packaging and installing or replacing hardware, touch an unpainted metal surface of the system for a minimum of 5 seconds.
Squeeze or lift the handle of the disk drive out toward you before you remove the disk drive, as shown in Figure 6. If the handle is not all the way out, the disk drive can not slide out of the system or expansion unit.

Replace the disk drive

Find the package that contains the new disk drive.
Attention: Disk drives are fragile. Handle with care.
Remove the disk drive from its protective package.
Unlock the disk drive handle by squeezing and pulling it out toward you before you install the disk drive. If the handle is not all the way out, the disk drive will not slide into the system or expansion unit.
If your replacement disk drive does not have a bezel preinstalled, then follow these steps to install the disk-drive bezel on the replacement disk drive:
1. Attach the bezel (A) to the disk drive, as shown in the following figure.

Enter either the physical location code or the PCI/SCSI location from which you removed the disk drive. Press Enter.
Specify action as 2 (Install device).
Enter a time value in minutes, allowing enough time for you to install the new disk drive.
The concurrent maintenance light for the slot indicates that you can install the disk drive.

Press Enter. A Device Concurrent Maintenance Action display is shown, similar to the following display.

Please insert the device located in:
    Location: U0.1-P1-I4/Z1-A8
```
Support the bottom of the disk drive as you align it with the guide rails in the system or expansion unit. Do not hold the disk drive by the handle.
Slide the disk drive all the way in into the system or expansion unit and then lock it in place by pushing in the disk drive handle as shown in Figure 13.
