6.2.11 Removing the Power Switch/LED Assembly
1. Power off the system, remove the system cover, and attach an antistatic wrist strap
as described in Chapter 5 “Preparing for Component Removal and Replacement.”
Caution – Use proper ESD grounding techniques when handling components. Wear
an antistatic wrist strap and use an ESD-protected mat. Store ESD-sensitive
components in antistatic bags before placing them on any surface.
2. Remove the front panel bezel by lifting the three tabs and gently lifting the bezel
from the system (

3. If any long PCI cards are installed, remove them.
See Section 8.4.1 “Removing a PCI Card” on page 8-12.
4. Move the peripheral assembly aside to provide clearance:
a. Open the cable routing clip below the peripheral assembly: this will release the
tension from the smart card and diskette drive cables. You do not have to
disconnect the cables.
b. Using a No. 2 Phillips screwdriver, loosen (but do not remove) the three screws
securing the peripheral assembly to the chassis (see
FIGURE 7-1
on page 7-2).
