1. What is the reason for technicians to wear special wrist grounding straps?

>To protect your self and your PC from being damage.

>to prevent electrostatic discharge (ESD) by safely grounding a person working on electronic equipment and avoid the components to destroyed

2. After installing a new computer component why is it important to obtain the most current driver for it?

3. What are the steps required to install a peripheral device?

>Adding a new peripheral device that is not-pluggable usually involves the following:

• Shutting down the system

• Connecting the device to the system

• Rebooting the system

Use How to Add a Peripheral Device to add the following devices that are not hot-pluggable to a system:

• CD-ROM

• Secondary disk drive

• Tape drive

• SBUS card

In some cases, you might have to add a third-party device driver to support the new device.

For information on hot-plugging devices, see Chapter 6, Dynamically Configuring Devices (Tasks).

How to Add a Peripheral Device

1. Become superuser.

2. (Optional) If you need to add a device driver to support the device, complete the procedure How to Add a Device Driver.

3. Create the /reconfigure file.

   # touch /reconfigure

   The /reconfigure file causes the Solaris software to check for the presence of any newly installed devices the next time you turn on or boot your system.

4. Shut down the system.

   # shutdown -i0 -g30 -y

   -i0

   Brings the system to the 0 init state, which is the appropriate state for turning the system power off for adding and removing devices.

   -g30

   Shuts the system down in 30 seconds. The default is 60 seconds.

   -y

   Continues the system shutdown without user intervention. Otherwise, you are prompted to continue the shutdown process.

5. Select one of the following to turn off power to the system after it is shut down:

   • For SPARC platforms, it is safe to turn off power if the ok prompt is displayed.

   • For x86 platforms, it is safe to turn off power if the type any key to continue prompt is displayed.

6. Turn off power to all peripheral devices.

   For the location of power switches on any peripheral devices, refer to the hardware installation guides that accompany your peripheral devices.

7. Install the peripheral device, making sure that the device you are adding has a different target number than the other devices on the system.

   Often, a small switch is located at the back of the disk for selecting the target number.

   Refer to the hardware installation guide that accompanies the peripheral device for information on installing and connecting the device.

8. Turn on the power to the system.

   The system boots to multiuser mode, and the login prompt is displayed.

9. Verify that the peripheral device has been added by attempting to access the device.

   For information on accessing the device, see Accessing Devices.

4. If a newly installed peripheral device does not function properly what steps can be taken to correct the problem?

> Check if the product or the hardware you bought has no defect or company defects.You should also check for driver updates for all your peripheral devices. If you're up to date, and you started having issues around the time you last updated a driver, try backing down to a lower version.


5. Explain the technique used to help protect data on a hard drive when doing a clean install?

6. Explain what a software patch is.

>As people begin to use a software program with frequency, they may note glitches or problems that were not observed during beta testing of the program. Alternately, older software can have compatibility issues with newer systems, or newer software may be incompatible with older systems. In these cases, and often to increase sales or use of software, programmers may create what is called a software patch, designed to fix small bugs, glitches, or address software-to-hardware or operating system compatibility issues.
