This chapter provides instructions for replacing the server components.
The following topics are included:
Use the procedures in this section to install a new air filter or to remove the air filter for cleaning.
Press the green tabs on both sides of the bezel, and pull the bezel forward and down (FIGURE 3-2).
 | Caution - Do not open the bezel on a flat surface. The front of the server must be hanging over the edge of a flat surface to avoid damaging the bezel hinges. |
Grasp the tabs, and lift the air filter from the bezel (FIGURE 3-2).
The server’s redundant hot-swappable power supplies enable you to remove and replace one or two power supplies without shutting the server down, provided that the other power supplies are online and working.
If a power supply fails and you do not have a replacement available, leave the failed power supply installed to ensure proper air flow in the server.
Identify which power supply requires replacement.
A lighted amber indicator on a power supply indicates that a failure was detected.
Grasp the power supply handle, and push the power supply latch to the right (FIGURE 3-4).
Remove the replacement power supply from its packaging, and place the power supply on an antistatic mat.
Slide the power supply into bay until it is fully seated (FIGURE 3-5).
Verify that the amber indicator on the replaced power supply and that the Service Required Indicators are not lit.
The hard drives in the server are hot-pluggable, but this capability depends on how the hard drives are configured. To hot-plug a drive, you must be able to take the drive offline by preventing any applications from accessing the drive and removing the logical software links to the drive.
The following situations inhibit the ability to perform hot-plugging of a drive:
The hard drive provides the operating system, and the operating system is not mirrored on another drive.
The hard drive cannot be logically isolated from the online operations of the server.
If your drive falls into one of these conditions, you must shut the system down before you replace the hard drive.
Note - Replacing a hard drive does not require removing the server from a rack. |
If the drive you want to remove cannot be hot-plugged, perform the tasks in Chapter 2 before you perform the steps in this procedure.
Open the bezel (FIGURE 3-6).
| Caution - Do not open the bezel on a flat surface. The front of the server must be hanging over the edge of a flat surface to avoid damaging the bezel hinges. |
Type the Solaris OS commands required to stop using the hard drive.
Exact commands required depend on the configuration of your hard drives. You might need to unmount file systems or perform RAID commands.
On the drive you plan to remove, push the latch release button (FIGURE 3-7).
| Caution - The latch is not an ejector. Do not bend it too far to the left. Doing so can damage the latch. |
Remove the replacement hard drive from its packaging, and place it on an antistatic mat.
Align the replacement drive to the drive slot.
The hard drive is physically addressed according to the slot in which it is installed. It is important to install a replacement drive in the same slot as the drive that was removed.
Slide the drive into the bay until it is fully seated (FIGURE 3-8).
Perform administrative tasks to reconfigure the hard drive.
The procedures that you perform at this point depend on how your data is configured. You might need to partition the drive, create file systems, load data from backups, or have it updated from a RAID configuration.
The optical media drive in the server is not hot-pluggable. You cannot remove it while the system is running.
Prepare the server for optical media drive removal.
See Chapter 2.
| Caution - Do not open the bezel on a flat surface. The front of the server must be hanging over the edge of a flat surface to avoid damaging the bezel hinges. |
Push the release tab to the left, and pull the probe forward, freeing the optical media drive (FIGURE 3-9).
Remove the optical media drive from server, and set it aside on an antistatic mat.
Remove the replacement optical media drive from its packaging, and place it on an antistatic mat.
Hold the tab to the left, and insert the optical media drive into the chassis (FIGURE 3-10).
Press the optical media drive in until it seats, and release the tab.
If you installed the optical media drive as part of another procedure, return to that procedure.
Otherwise, perform the tasks needed to bring the server back online.
See Chapter 4.
Use the FB-DIMM configuration rules to help you plan the memory configuration of your server. There are 32 slots that hold industry-standard FB-DIMM memory modules. General rules are:
FB-DIMMs must be installed in identical pairs (that is, the same size, speed, and organization).
A replacement FB-DIMM must have the same part number as the other FB-DIMM in its pair. If you are unable to obtain a matching FB-DIMM, you must replace both FB‐DIMMs in the pair.
FB-DIMM pairs must be installed in the following slot order: A0/B0, C0/D0, A1/B1, then C1/D1.
FB-DIMM capacities can be different between slots. For example, you can install a pair of 2-GB FB-DIMMs in slots A0 or B0 and a pair of 1-GB FB-DIMMs in slots C0 or D0.
Highest capacity FB-DIMMs must be installed in the lowest numbered slots. For instance, if you have four 4-GB FB-DIMMs and four 2-GB FB-DIMMs, you must install the 4-GB FB-DIMMs in slots A0/B0 and C0/D0, and you must install the 2-GB FB-DIMMs in slots A1/B1 and C1/D1.
 | Caution - Ensure that all power is removed from the server before removing or installing FB-DIMMs. You must disconnect the power cables before performing this procedure. |
Note - FB-DIMM names in ILOM messages are displayed with the full FRU name, such as /SYS/MB/CMP0/BR0/CH0/D0. |
| Caution - Always perform antistatic measures by using a wrist strap and an antistatic mat for handling and storing removable components. |
The system Service Required Indicator lights if the system detects a FB-DIMM fault. See Memory Fault Handling.
Prepare the server for FB-DIMM removal.
See Chapter 2.
Press the FB-DIMM fault locator button.
The button is located on the left edge of the memory mezzanine.
Note the location of faulty FB-DIMMs.
Faulty FB-DIMMs are identified with a corresponding amber indicator.
Note - The FB-DIMM fault indicator remains lit only for a few minutes. |
Ensure that all FB-DIMMs are seated correctly in their slots.
If you have not already done so, prepare the server for FB-DIMM removal.
See Chapter 2.
Push down on the ejector tabs on each side of the FB-DIMM until the FB‐DIMM is released (FIGURE 3-13).
Grasp the top corners of the faulty FB-DIMM, and remove it from the memory mezzanine.
Repeat Step 2 through Step 4 to remove any additional FB-DIMMs.
If you are adding memory, prepare the server for service.
See Chapter 2.
Unpackage the FB-DIMMs, and place them on an antistatic mat.
Line up the replacement FB-DIMM with the connector (FIGURE 3-14).
Align the FB-DIMM notch with the key in the connector. This ensures that the FB-DIMM is oriented correctly.
Push the FB-DIMM into the connector until the ejector tabs lock the FB-DIMM in place.
If the FB-DIMM does not easily seat into the connector, verify that the orientation of the FB-DIMM is as shown in FIGURE 3-14. If the orientation is reversed, damage to the FB-DIMM might occur.
Repeat Step 3 through Step 5 until all replacement FB-DIMMs are installed.
If you installed FB-DIMMs as part of another procedure, return to that procedure.
If you are only installing FB-DIMMs, see Chapter 4 for the tasks needed to bring the server back online.
