Installing Server Options |
This chapter describes how to install optional components into the Sun Fire X4170, X4270, and X4275 Servers. Topics discussed in this chapter include:
Before installing the server options into the server chassis, you should review these topics:
Before you begin the installation of the options, you should have:
Internal modules and options are electronic components that are extremely sensitive to static electricity. Ordinary amounts of static from your clothes or work environment can destroy components.
To prevent static damage whenever you are accessing any of the internal server components, you must:
Before you install server options, you should always run diagnostics on the server to ensure that the server is operating properly. After you install the server options, you should run the diagnostics again. This approach will ensure that the server is working properly before you place the server in service.
For instructions for running diagnostics on a server that is being installed for the first time or a server that is already in service, see the Sun x64 Servers Diagnostics Guide.
Each server is shipped with module-replacement filler panels for CPUs, hard disk drives (HDDs), memory modules (DIMMs), PCIe cards, and power supplies. These filler panels are installed at the factory and must remain in the server until you replace them with a purchased module.
As needed, consult the following sections when installing server option:
A filler panel is an empty metal or plastic enclosure that does not contain any functioning system hardware or cable connectors. These panels must remain in any unused module slots (CPU, HDDs, DIMMs, PCIe cards, power supplies) to ensure proper air flow throughout the system. If you remove a filler panel and continue to operate your system with an empty module slot, the operating performance of your system could decline.
Before you can install a server option into the server, you must remove the filler panel from the location into which you intend to install the option. When you remove an option from the server, you must install either a replacement option or a filler panel.
TABLE 2-1 describes how to remove and install server filler panels.
Electrostatic discharge (ESD) sensitive devices, such as the PCIe cards, hard drives, CPUs, and memory cards, require special handling.
|
Caution - You must disconnect both power supplies before servicing some of the components documented in this chapter. |
Wear an antistatic wrist strap and use an antistatic mat when handling components such as hard drive assemblies, circuit boards, or PCIe cards. When servicing or removing server components, attach an antistatic strap to your wrist and then to a metal area on the chassis. Following this practice equalizes the electrical potentials between you and the server.
| Note - An antistatic wrist strap is not shipped with the servers. However, antistatic wrist straps are included with options. |
Place ESD-sensitive components on an antistatic mat.
1. Prepare an antistatic surface to set parts on during the removal, installation, or replacement process.
Place ESD-sensitive components such as the printed circuit boards on an antistatic mat. The following items can be used as an antistatic mat:
2. Attach an antistatic wrist strap.
When servicing or removing server components, attach an antistatic strap to your wrist and then to a metal area on the chassis.
Before you can install any server options, you must prepare the server.
|
To prepare the server to install the options, complete the following tasks:
See Opening the Box.
2. Ensure that the server AC power cord (or cords) is disconnected from the server.
3. Remove the server top cover.
Before you remove the server top cover, you must ensure that no power is being applied to the server.
See Removing the Server Top Cover.
| Note - If you are installing an HDD or a power supply, it is not necessary to remove the server top cover. |
The procedure for removing the server top cover varies depending on the server type.
|
1. Ensure that the AC power cords are disconnected from the server power supplies.
2. Unlatch the fan module door (FIGURE 2-1 [1]).
Pull the two release tabs back to release the door. Rotate the fan door to the open position and hold it there.
| Note - FIGURE 2-1 shows the Sun Fire X4170 Server, not the Sun Fire X4270 Server; however, the procedure for removing the top cover is the same for both servers. |

To avoid damage, ensure that you follow antistatic practices as described in Performing Electrostatic Discharge and Antistatic Prevention Measures. |
The servers support a variety of DIMM configurations that can include quad-rank (QR) DIMMs, dual-rank (DR) DIMMs, or single-rank (SR) DIMMs. When replacing or upgrading a DIMM on the server you should consider the following:
For details, see DIMM and CPU Physical Layout.
For details, see DIMM Population Rules.
For details, see Install DIMMs.
For details, see DIMM Rank Classification Labels.
The physical layout of the DIMMs and CPUs is shown in FIGURE 2-3 and TABLE 2-2.
FIGURE 2-3 CPU and DIMM Physical Layout
The DIMM population rules for the Sun Fire X4170, X4270, and X4275 Servers are as follows:
1. Do not populate any DIMM sockets next to an empty CPU socket. Each processor contains a separate memory controller.
2. Each CPU can support a maximum of:
3. Populate DIMMs by location according to the following rules:
For example, populate D8/D5/D2 first; then D7/D4/D1 second; and finally, D6/D3/D0. See FIGURE 2-3.
Note that QR DIMMs are supported only in white sockets if adjacent blue socket contains a QR DIMM.
4. For maximum performance, apply the following rules:
|
DIMM speed rules are as follows:
|
|
|
The system operates all memory only as fast as the slowest DIMM configuration. |
DIMMs come in a variety of ranks: single, dual, or quad. Each DIMM is shipped with a label identifying its rank classification. TABLE 2-4 identifies the corresponding rank classification label shipped with each DIMM.
|
1. Attach an antistatic wrist strap.
2. Prepare the server to install options.
See Preparing the Server to Install Options.
3. Unpack the DIMMs and place them on an antistatic mat.
4. Determine the rank classification of the DIMMs to be installed.
See DIMM Rank Classification Labels.
5. To determine the slots into which to install the DIMMs, review the DIMM population rules to ensure that you are installing the DIMMs in a location that is consistent with the rules.
If you violate DIMM population rules, the performance of the server might be adversely affected.
6. To install a DIMM, do the following:
a. Remove the DIMM filler panel.
See Filler Panel Removal and Installation.
b. Ensure that the DIMM connector ejector levers are in the open position.
c. Align the DIMM with the connector (FIGURE 2-4).
Align the notch in the DIMM with the key in the connector. The notch ensures that the DIMM is oriented correctly.
d. Push the DIMM into the connector slot until both ejector levers close, locking the DIMM in place.
If the DIMM does not easily seat into the connector, verify that the notch in the DIMM is aligned with the key in the connector as shown in FIGURE 2-4. If the notch is not aligned, damage to the DIMM might occur.
e. Repeat Step a through Step d until all DIMMs are installed.
See Installing the Server Top Cover.
The server is shipped with at least one preinstalled CPU. The server can support a maximum of two CPUs. If you ordered a second CPU as an option for the server, the kit contains a CPU chip and a heatsink with thermal grease pre-applied.

Caution - CPU options should be installed only by a Sun qualified service technician. |
1. Attach an antistatic wrist strap.
2. Prepare the server to install options.
See Preparing the Server to Install Options.
The kit includes a CPU chip and a heatsink with the thermal grease pre-applied.
4. Install the CPU (FIGURE 2-5).
a. Properly orient the CPU with the socket alignment tabs and carefully place the CPU into the socket [1].
Ensure that the orientation is correct as damage might result if the CPU pins are not aligned correctly.
Ensure that the pressure frame sits flat around the periphery of the CPU.
c. Engage the release lever by rotating it downward and slipping it under the catch [2].
d. Orient the heatsink so that the two screws line up with the mounting studs [3].
e. Carefully position the heatsink on the CPU, aligning it with the mounting posts to reduce movement after it makes initial contact with the layer of thermal grease [3].
|
|
Caution - If the heatsink assembly is moved too much during its installation, the layer of thermal grease may not be distributed evenly, leading to component damage. |
f. Tighten the screws alternately one-half turn until fully seated.
