The following topics are covered:
This section describes important safety information that you need to know prior to removing or installing parts in the Sun Fire X4270 M2 Server.
|
Caution - Hazardous voltage present.Never attempt to run the server with the cover removed. |
|
Caution - Equipment damage possible.The covers must be in place for proper airflow. |
For your protection, observe the following safety precautions when setting up your equipment:
The Sun Fire X4270 M2 Server can be serviced with the following tools:
To obtain support for your server, you need your chassis serial number. The chassis serial number is located on a sticker on the front of the server and on another sticker on the top of the server.
Refer to the following topics in this section to power on and off a server:
1. Verify that the server is in the standby power state.
In the standby power state, the OK/Power LED on the front panel of the server blinks (0.1 second on, 2.9 seconds off). The standby power state indicates that the server SP is active but the server host is powered off.
For the location of the OK/Power LED, see FIGURE 1-1.
2. Apply full power to the server SP and host.
For the location of the Power button on the server, see FIGURE 1-1.
The Power/OK LED illuminates a SLOW BLINK while the system is executing its BIOS firmware. The Power/OK LED illuminates STEADY ON when the BIOS firmware completes and the operating system boot begins.
To remove main power from the server, use one of the methods shown in the following table.
|
Press and release the Power button on the front panel (FIGURE 1-1). Pressing the power button causes Advanced Configuration and Power Interface (ACPI)-enabled operating systems to perform an orderly shutdown of the operating system. Servers not running ACPI-enabled operating systems will shut down to standby power mode immediately. Note - Some operating systems might prompt the user for confirmation of the shutdown before actually turning off the system. |
|
|
Press and hold the Power button for at least five seconds until the main power is off and the server enters standby power mode (FIGURE 1-1). |
|
|
|
|
|
See Power Off the Server Using the ILOM SP Command-Line Interface. |
|
|
Caution - To completely power off the server, you must disconnect the AC power cords from the back panel of the server. |
You can use the ILOM service processor (SP) to perform a graceful shutdown of the server and ensure that all of your data is saved and the server is ready for restart.
ssh root@host (Where host is either a hostname, when using DNS, or an ipaddress.)
Password: root_password (The default password is changeme.)
The ILOM command-line interface (CLI) prompt appears (->).
Depending on the type of problem, you might want to view server status or log files, or run diagnostics before you shut down the server.
2. Notify affected users that the server will be shut down.
3. Save any open files and quit all running programs.
Refer to your application documentation for specific information.
4. Power down the server. Type:
-> stop /SYS (for a Graceful shutdown as defined in TABLE 2-1)
-> stop -f/SYS (for an Emergency Shut as defined in TABLE 2-1)
For additional information, refer to the Oracle Integrated Lights Out Manager (ILOM) 3.0 Documentation Collection (formerly called the Sun Integrated Lights Out Manager).
The Basic Input/Output System (BIOS) has a Setup Utility stored in the BIOS flash memory. The Setup Utility reports system information and can be used to configure the BIOS settings. The configurable data is provided with context-sensitive help and is stored in the system's battery-backed CMOS RAM. If the configuration stored in the CMOS RAM is invalid, the BIOS settings return to their default optimal values.
There are seven menus in the BIOS Setup Utility, which appear in this order: Main, Advanced, PCI, Boot, Security, Chipset, and Exit. To navigate the menus or options listed on the menu, use the arrow keys. The options or fields that you can configure on a menu appear in color. For further instructions on how to navigate and change settings in the BIOS Setup Utility, refer to the online instructions provided on the menu.
For additional information about the BIOS operations and menu options available on your server, refer to the following sections:
Refer to the following sections for information when booting the BIOS and other
set up considerations:
At system startup, the BIOS performs a power-on self-test that checks the hardware on your server to ensure that all components are present and functioning properly. TABLE 2-2 identifies the events that can occur during BIOS POST, as well as specifies whether these events can prevent the host from powering-on.
|
Memory Correctable ECC (error correction code) error detected |
||
|
All installed memory has experienced an unrecoverable failure |
||
Each power-on-self-test (POST) diagnostic is a low-level test designed to pinpoint faults in a specific hardware component. If the POST diagnostic discloses an F1 or F2 error, it typically reports the following information about the error:
TABLE 2-3 lists some of the F1 and F2 error messages that could appear during the POST diagnostics along with instructions for how to possibly resolve the error reported.
The BIOS POST memory testing is performed as follows:
1. The first megabyte of DRAM is tested by the BIOS before the BIOS code is copied from ROM to DRAM.
2. After exiting out of DRAM, the BIOS performs a simple memory test (where a write/read of every location with the pattern 55aa55aa is performed).
| Note - The simple memory test is performed only if Quick Boot is not enabled from the Boot Settings Configuration screen. Enabling Quick Boot causes the BIOS to skip the memory test. |
3. The BIOS polls the memory controllers for both correctable and non-correctable memory errors and logs those errors into the SP.
4. The message, BMC Responding appears at the end of POST.
The server supports four 10/100/1000BASE-T Gigabit Ethernet ports on the rear of the chassis. For port locations, see FIGURE 1-2.
The device naming for the Ethernet interfaces is reported differently by different interfaces and operating systems. See TABLE 2-4 for the physical (BIOS) and logical (operating system) naming conventions used for each interface.

eth0[1] |
||||
|
eth0[2] |
||||
|
eth0[3] |

|
vmnic#[4] |
The order in which the BIOS detects the Ethernet ports during boot time, and the corresponding drivers that control those ports, are listed below:
TABLE 2-5 provides descriptions for the seven top-level BIOS setup menus.
See BIOS Setup Utility Menu Screens for examples of each of these screens.
FIGURE 2-1 identifies the sub-menus that you can access from each of the seven top-level BIOS menus.

5. Set the server on a sturdy work surface.
Each server is shipped with module-replacement filler panels for CPUs, storage drives, DDR3 memory modules (DDR3 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 option.
As needed, consult the following sections when removing and replacing a server component:
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, storage drives, DDR3 DIMMs, PCIe cards, power supplies) to ensure proper airflow 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 optional server component into the server, you must remove the filler panel from the location into which you intend to install the component. When you remove a CPU, storage drive, DDR3 DIMM, PCIe card, or a power supply from the server, you must install either a replacement for component removed or a filler panel.
TABLE 2-7 describes how to remove and install server filler panels.
Electrostatic discharge (ESD) sensitive devices, such as the motherboards, PCIe cards, storage drives, and memory cards, require special handling.
|
|
Caution - You must disconnect both power supplies before servicing any of the components documented in this chapter. |
Wear an antistatic wrist strap and use an antistatic mat when handling components such as storage 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 included in the Accessory Kit for the Sun Fire X4270 M2 Server. However, antistatic wrist straps are still included with options and components. |
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.
