Servicing Customer-Replaceable Devices |
This chapter describes how to replace the hot-swappable and hot-pluggable customer-replaceable units (CRUs) in the Sun Fire X4440 Server. A customer-replaceable unit can be replaced by anyone.
The following topics are covered:
Hot-pluggable devices can be removed and installed while the server is running, but you must perform administrative tasks before or after installing the hardware (for example, mounting a drive).
In the Sun Fire X4440, only drives are hot-pluggable. To hot-plug a drive you must take the drive offline (to prevent any applications from accessing it, and to remove the logical software links to it) before you can safely remove it. See Servicing Drives.
Hot-swappable devices can be removed and installed while the server is running without affecting the rest of the server’s capabilities.
In the Sun Fire X4440, the following devices are hot-swappable:
| Note - The chassis-mounted drives can be hot-swappable, depending on how they are configured. See Servicing Drives. |
The following topics are covered:
| Note - CRU: This customer-replaceable unit can be replaced by anyone. |
TABLE 3-1 shows physical drive locations for a Sun Fire X4440 server with 8 drives.
Drives can be hot-plugged or cold-plugged. Drives in the Sun Fire X4440 might be hot-pluggable, depending on the drive configuration.
To hot-plug a drive you must take the drive offline (to prevent applications from accessing it, and to remove the logical software links to it) before you can safely remove it.
To remove a drive from a Sun Fire X4440:
1. Identify the drive you want to remove.
The amber Service Required LED might be lit. For specific drive locations, see Sun Fire X4440 Server Drive Guidelines.
2. Determine if the drive can be hot-plugged, or cold-plugged.
The following conditions might prevent you from hot-plugging a drive. You must power off the server, if the drive:
Unconfigure the drive, as required. You must take the drive offline before you can safely remove it. Placing the drive offline prevents applications from accessing the drive, and removes logical software links to the drive.
See one of the following HBA documents, if your system uses RAID:
For Sun StorageTek: Sun StorageTek RAID Manager Software User's Guide
For LSI MegaRAID Storage Manager (MSM): x64 Server Utilities Reference Manual
You must power off the server before you can safely remove the drive. Do one of the procedures described in Powering Off the Server.
4. On the drive you plan to remove, push the drive release button to open the latch (FIGURE 3-3 [1]).
5. Grasp the latch [2] and pull the drive out of the drive slot [3].
|
Caution - The latch is not an ejector. Do not bend it too far to the right. Doing so can damage the latch. |
FIGURE 3-3 Locating the Drive Release Button and Latch
Installing a drive into the Sun Fire X4440 Server is a two-step process. You must first install a drive into the drive slot, and then configure that drive to the server.
|
|
Caution - Before inserting a replacement drive, wait 15 seconds, and verify that your monitoring or administration application has detected the missing or failed drive. |
To install a drive into a Sun Fire X4440 server:
1. If necessary, remove the drive fillers from the chassis.
The Sun Fire X4440 might have as many as eight drive fillers covering unoccupied drive slots.
2. Determine the drive slot location for the replacement drive.
If you removed an existing drive from a slot in the server, you must install the replacement drive in the same slot as the drive that was removed. Drives are physically addressed according to the slot in which they are installed. See TABLE 3-1 for drive locations.
3. Slide the drive into the drive slot until it is fully seated. (FIGURE 3-4)
4. Close the latch to lock the drive in place.
Configure the drive. See one of the following HBA documents:
For Sun StorageTek: Sun StorageTek RAID Manager Software User's Guide
For LSI MegaRAID Storage Manager (MSM): x64 Server Utilities Reference Manual
Restore power to the server. Do the procedure described in Powering On the Server.

Six pairs of fan modules are located under the top cover door, providing N+1 cooling redundancy. Each fan module contains two fans mounted in an integrated, hot-swappable CRU.
If a fan module fails, replace the fan as soon as possible to maintain server availability.
Fan modules are hot-swappable and can be removed and installed while the server is running without affecting the rest of the server’s capabilities.
Each fan module contains LEDs that are visible when you open the fan tray access door. TABLE 3-4 describes fan tray module LEDs and their functions.
FIGURE 3-6 shows the fan module locations.
FIGURE 3-6 Fan Module Locations
The following LEDs are lit when a fan module fault is detected:
If an overtemperature condition occurs, the front panel CPU overtemperature LED becomes lit and a message is displayed on the console and logged by the ILOM. Refer to the Sun Integrated Lights Out Manager User's Guide.
The system Overtemp LED might be lit if a fan fault causes an increase in system operating temperature. See Chapter 1, Sun Fire X4440 Front Panel Features for more information about system status LEDs.
