Memory module The computer has four memory module sockets. CAUTION: You must disconnect the power cord and wait approximately 30 seconds for the power to drain before adding or removing memory modules. Regardless of the power-on state, voltage is always supplied to the memory modules as long as the computer is plugged into an active AC outlet. Adding or removing memory modules while voltage is present may cause irreparable damage to the memory modules or system board. The memory module sockets have gold-plated metal contacts. When upgrading the memory, it is important to use memory modules with gold-plated metal contacts to prevent corrosion and/or oxidation resulting from having incompatible metals in contact with each other. Static electricity can damage the electronic components of the computer or optional cards. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object. When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the module. Follow these steps to remove a memory module: 1. Prepare the computer for disassembly (see Preparation for disassembly on page 30). 2. Remove the front bezel (see Front bezel on page 34). 3. Remove the drive cage (see Drive cage on page 38). Remove the memory module: 1. Open both latches (1) of the memory module socket. 2. Remove the memory module (2) from the socket. NOTE: Memory modules are designed with notches to prevent incorrect insertion. Reverse this procedure to install a memory module. Reconfigure the computer, if necessary. Memory module 43

The computer has four memory module sockets.
CAUTION:
You must disconnect the power cord and wait approximately 30 seconds for the power to drain
before adding or removing memory modules. Regardless of the power-on state, voltage is always supplied to
the memory modules as long as the computer is plugged into an active AC outlet. Adding or removing memory
modules while voltage is present may cause irreparable damage to the memory modules or system board.
The memory module sockets have gold-plated metal contacts. When upgrading the memory, it is important to
use memory modules with gold-plated metal contacts to prevent corrosion and/or oxidation resulting from
having incompatible metals in contact with each other.
Static electricity can damage the electronic components of the computer or optional cards. Before beginning
