Servicing Customer-Replaceable Devices |
This chapter describes how to replace the hot-swappable and hot-pluggable customer-replaceable units (CRUs) in the Sun Fire X4140 Server.
The following topics are covered:
Some of the procedures in this section are for customer-replaceable units (CRUs) and some are for field-replaceable units (FRUs), as noted in the procedures. FRU components should be replaced only by trained service technicians. Contact your Sun Service representative for assistance with FRU replacements.
Hot-pluggable devices are those devices that you can remove and install while the server is running, but you must perform administrative tasks before or after installing the hardware (for example, mounting a hard drive or SSD).
In the Sun Fire X4140 Server, 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 are those devices that can be removed and installed while the server is running without affecting the rest of the server’s capabilities.
In the Sun Fire X4140 Server, 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: These customer-replaceable units can be replaced by anyone. |
TABLE 3-1 shows physical drive locations for the Sun Fire X4140 Server with 8 drives. FIGURE 3-1 shows the server front panel, and FIGURE 3-2 shows the drive status LEDs.
The X4150 server supports installing SSDs in the drive bays. Each SSD provides at least 32Gb of SATA capacity.
TABLE 3-1 shows drive numbers for a server with 4 SSDs and 4 hard drives. FIGURE 3-1 shows the front panel of a server with 8 drives.
The Sun Fire X4140 servers support solid-state drives (SSDs) under the following conditions:
Sun Fire X4140 with on-board controller:
Note - You can create RAID volumes with SAS HDDs and SATA SSDs, as long as you do not mix them in a same volume. |
The following cable kits are used for the HBA controller when using hard drives and SSDs:
The following cable kits are used for the on-board controller with SSDs:
When replacing or installing a SSD to be included in a RAID configuration, in the Sun Fire X4140 system, make sure that the firmware on the newly installed SSD is the same as the firmware that is installed on the other SSDs in the RAID volume.
FIGURE 3-2 shows the hard drive and SSD LED status indicators.
Drives can be hot-plugged or cold-plugged. Drives in the Sun Fire X4140 Server might be hot-pluggable, depending on the drive configuration.
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.
To remove a drive from a Sun Fire X4140 Server:
1. Identify the drive you wish to remove.
The amber Service Required LED might be lit. For specific drive locations, see Sun Fire X4140 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:
i. Unconfigure the drive, as required. 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 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
i. Wait until the blue OK to Remove LED becomes lit (FIGURE 3-2) before you physically uninstall the drive from the chassis.
The blue LED indicates that the drive is unconfigured and can be removed.
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 ([1] FIGURE 3-3).
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 X4140 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/administration application has detected the missing/failed drive. |
To install a drive into a Sun Fire X4140 Server:
1. If necessary, remove the drive fillers from the chassis.
The Sun Fire X4140 Server 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.
All drive slots in the Sun Fire X4240 Server must have drive fillers in place during operation to maintain airflow. To remove fillers, pull the ejector and pull the filler out of the chassis. (FIGURE 3-5)
The following topics are covered:
Note - CRU: This customer-replaceable unit can be replaced by anyone. |
Seven 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.
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 fan tray module LED locations.
FIGURE 3-6 Fan Module Status LEDs
See Sun Fire X4140 Server Chassis Overview for more information about system status LEDs.
The following LEDs are lit when a fan module fault is detected:
If an overtemperature condition occurs, the front panel processor overtemperature LED becomes lit and a message is displayed on the console and logged by the ILOM.
The system Overtemp LED might be lit if a fan fault causes an increase in system operating temperature. See Sun Fire X4140 Server Front Panel Features for more information about identifying and interpreting system LEDs.
Caution - Hazardous moving parts. Unless the power to the server is completely shut down, the only service permitted in the fan compartment is the replacement of the fan modules by trained personnel. |
1. Extend the server into the maintenance position.
See Extending the Server to the Maintenance Position.
2. Unlatch the fan module door.
Pull the release tabs back to release the door. Open the top cover toward the rear of the server.
3. Identify the faulty fan module with a corresponding Service Required LED.
The Fan Fault LEDs are located on the fan board.
4. Using thumb and forefinger in between the two fans, pull the fan module up and out of the connector.

2. Apply firm pressure to fully seat the fan module.
3. Verify that Fan OK LED is lit, and that the Fan Fault LED on the replaced fan module is not lit.
5. Verify that the Top Fan LED, Service Required LEDs, and the Locator LED/Locator button are not lit.
See Sun Fire X4140 Server Front Panel Features for more information about identifying and interpreting system LEDs.
Some versions of the Sun Fire X4140 Servers are equipped with redundant hot-swappable power supplies. Redundant power supplies enable you to remove and replace a power supply without shutting the server down, if the other power supply is 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.
See Power Supply LED Reference for specific information about power supply status LEDs.
The following topics are covered:
