Installation Sequence

It is very important that you follow this sequence of steps to ensure

the proper installation of any optional equipment.

1. If your computer includes the Smart Cover Lock feature and you

have set the lock, use Computer Setup to unlock the lock and

disable the Smart Cover Sensor.

For more information about Computer Setup, refer to the Computer

Setup Guide.

2. If the computer is already on, turn it off and disconnect the

power cord from the wall outlet.

WARNING: To reduce the risk of personal injury from electrical shock

and/or hot surfaces, be sure to disconnect the power cord from the wall

outlet, and allow the internal system components to cool before

touching.

WARNING: To reduce the risk of electrical shock, fire, or damage to

the equipment, do not plug telecommunications or telephone

connectors into the network interface controller (NIC) receptacles.

CAUTION: Static electricity can damage the electronic components of

the computer or optional equipment. Before beginning these

procedures, ensure that you are discharged of static electricity by

briefly touching a grounded metal object. See Appendix E,

“Electrostatic Discharge,” for more information.

3. Open the computer by removing its outside cover. See the

section “Removing the Access Panel.”

Hardware Reference Guide 2-1

Hardware Upgrades

4. Install any optional equipment. See the applicable sections of

this guide or refer to the documentation provided with the

optional equipment for instructions.

5. Replace the computer cover.

6. Turn on the monitor, computer, and any devices you want to test.

7. Reconfigure the computer, if necessary. Refer to the Computer

Setup Guide for instructions about using Computer Setup.

If you normally lock the Smart Cover Lock, use Computer Setup to

relock the lock and enable the cover removal sensor.

Smart Cover Lock

The Smart Cover Lock is an optional feature included on select

models only.

The Smart Cover Lock is a software-controllable cover lock,

controlled by the setup password. This lock prevents unauthorized

access to the internal components. The computer ships with the

Smart Cover Lock in the unlocked position. For more information

about locking the Smart Cover Lock, refer to the Desktop

Management guide.

Using the Smart Cover FailSafe Key

If you enable the Smart Cover Lock and cannot enter your password

to disable the lock, you will need a Smart Cover FailSafe Key to

open the computer cover. You will need the key in any of the

following circumstances:

■

Power outage

■

Startup failure

■

PC component (for example, processor or power supply) failure

■

Forgotten password
