Observe the post-installation instructions described on page 32. 46 3 Upgrading the system Upgrading the CPU This section includes instructions for removing and installing a CPU. To remove a CPU with heatsink Before you can install a new CPU in a socket, remove first any previously installed CPU from that socket. Important: Before removing a CPU from the mainboard, make sure to create a backup file of all important data. 1 2 3 Observe the ESD precautions and pre-installation procedures described on page 31. To detach the CPU from its socket, follow the steps below: (1) Depress then lift up the retainer lever up to a 90° angle. (2) Pull out the CPU from the socket. Warning!The heatsink becomes very hot when the system is on. NEVER touch the heatsink with any metal or with your hands. 47 To install a CPU with heatsink If only one CPU is to be installed, it must be installed in the CPU 1 socket; if such is the case, the CPU 2 socket no longer requires a termination module. 1 2 3 Observe the ESD precautions and pre-installation procedures described on page 31. Align the CPU to its socket, making sure that pin 1 (indicated by the notched corner) of the CPU connects to hole 1 of the socket (on the bottom right corner). To install the CPU to its socket, follow the steps below: (1) Insert the CPU into the socket. (2) Press down the retainer lever to lock the CPU in place. 4 5 Observe the post-installation instructions described on page 32. 48 3 Upgrading the system Upgrading the system memory This section includes instructions for removing and installing a memory module. Memory modules must be installed and removed in pairs, observing sequential slot positions. To remove a DIMM Before you can install a new DIMM in a socket, remove first any previously installed DIMM from that socket. Important: Before removing any DIMM from the mainboard, make sure to create a backup file of all important data. 1 2 3 4 Observe the ESD precautions and pre-installation procedures described on page 31. Electrostatic discharge can damage electronic components. Make sure that you are properly grounded before handling a power supply module. 53 To install a redundant power supply module 1 Remove the screw securing the cover of the empty power supply module bay, then detach the cover. 2 Slide the power supply module into the empty bay until you feel resistance. 54 3 3 Upgrading the system Press the module handle to secure the power supply module to its bay. 4 Verify that the power indicators on both the main power supply and on the newly installed power supply are illuminated (green). 55 Installing a hot-swappable HDD fan The Altos G700 series server accommodates two hot-swappable HDD fans. Note: The illustrations used in this section shows the Altos G701 server chassis. To remove a hot-swappable HDD fan Caution!To reduce the risk of personal injury, avoid contact with the fan when the blades are still moving. 1 2 3 Place the system unit on a flat, stable surface. Detach the chassis panels and remove the air baffle. Grasp the release bracket on both sides of the fan (1) then pull it out. 56 3 Upgrading the system To install a hot-swappable HDD fan 1 2 Detach the chassis panels and remove the air baffle.

Since most systems are already properly configured and optimized, there is no need to run this utility. You will need to run this utility under the following conditions: · · When changing the system configuration When a configuration error is detected by the system and you are prompted ("Run Setup" message) to make changes to the BIOS setup Note: If you repeatedly receive Run Setup messages, the battery may be bad. In this case, the system cannot retain configuration values in CMOS. Ask a qualified technician for assistance. · · · When redefining the communication ports to prevent any conflicts When making changes to the Power Management configuration When changing the password or making other changes to the security setup BIOS setup loads the configuration values in a battery-backed nonvolatile memory called CMOS RAM. This memory area is not part of the system RAM which allows configuration data to be retained when power is turned off. [. . . ] For more information, refer to the documentation that came with your system rack. The distance from the center of two holes with closer spacing to the center of the next pair is equivalent to 1U. When installing components, you must start your measurement from the center of the two holes with closer spacing. Otherwise, the screw holes on the component may not match those on the rack. 103 Screw types for rack installation The following screws are used in the assembly of the Acer Altos G701 and other rack-mountable components.
