Servicing Customer Replaceable Devices |
This chapter describes how to replace the hot-swappable and hot-pluggable customer replaceable units (CRUs) in the Sun Fire X4150 Server.
The following topics are covered:
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 drive).
In the Sun Fire X4150 Server, hard drives and SSD 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 Section 3.2, Servicing the 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 X4150 Server, the following devices are hot-swappable:
| Note - The chassis-mounted drives can be hot-swappable, depending on how they are configured. See Section 3.2, Servicing the Drives. |
The following topics are covered for hard drive or SSD:
| Note - These are customer-replaceable units. |
FIGURE 3-1 shows the front panel of a server with 8 hard drives.
The X4150 server supports installing SSDs in the drive bays. Each SSD provides at least 32Gb of SATA capacity.
TABLE 3-2 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 X4x50 servers support solid-state drives (SSDs) under the following conditions:
Sun Fire X4150 with on-board controller:
Sun Fire X4150 with both HBA and on-board controller:
The remaining slots can be filled with up with hard drives that can equal up to 4.
| Note - You can create RAID volumes with SAS hard drives 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:

Hard drives or SSD drives can be hot-plugged or cold-plugged. Drives in the Sun Fire X4150 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 X4150 Server:
1. Identify the drive you wish to remove.
The amber Service Required LED might be lit. For specific drive locations, see Section 3.2.1, Sun Fire X4150 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:
a. 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:

Installing a hard drive or SSD drive into the Sun Fire X4150 Server is a two-step process. You must first install a drive into the drive slot, and then configure that drive to the server.
To install a drive or SSD drive into a Sun Fire X4150 Server:
1. If necessary, remove the blank panel from the chassis.
The Sun Fire X4150 Server might have as many as seven blank panels 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 Section 6.4, Powering On the Server.
All drive slots in the Sun Fire X4150 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.
The following topics are covered:
| Note - This is a customer-replaceable unit. |
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 3-5 Fan Module Status LEDs
See Section 1.2, Sun Fire X4150 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 conditions occurs, the front panel CPU 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 Section 1.3, Sun Fire X4150 Server Front Panel Features for more information about identifying and interpreting system LEDs.
