2.4 Powering Off the Server Module

To remove main power from the server module, choose one of the methods described in the following table.

TABLE 2-1 Shutdown Procedures
Shutdown	Method
Graceful shutdown	Use a pen, or other non-conducting pointed object, to press and release the Power/Standby Button on the front panel. When the main power is off, the OK LED on the front panel blinks, indicating that the server module is in standby power mode. See FIGURE 2-2. Pressing the Power/Standby Button causes Advanced Configuration and Power Interface (ACPI)-enabled operating systems to perform an orderly shutdown of the operating system. Server modules not running ACPI-enabled operating systems might ignore this event and the host will not shut down.
Immediate shutdown	Press and hold the Power/Standby Button for at least four seconds until the main power is off and the server module enters standby power mode. See FIGURE 2-2. When the main power is off, the OK LED on the front panel flashes, indicating that the server module is in standby power mode.
	Caution - All applications and files will be closed abruptly without saving changes. Possible data loss and file system corruption might occur.
ILOM SP CLI shutdown	See Powering Off Using the SP CLI.
ILOM SP Web Interface shutdown	See Powering Off Using the SP Web Interface.
Complete power removal	To completely power off the server module, you must disengage the server module from the midplane connector inside the chassis. To completely remove power from a server module, do the following: Place the server module in standby power mode. Unconfigure the server module using ILOM commands. Pull the server module out 3 inches from the rack using the ejectors. If you remove the server module completely, insert a filler panel in its place within 60 seconds.

Caution - Do not reinsert a server module until at least 20 seconds has elapsed since the server module was disengaged from the midplane connector.

Caution - Server modules should be removed only if the blue LED is lit, or if you are certain that a firmware update is not in progress. Pulling the server module out of the chassis during a firmware update might damage the server module, which might not be repairable in the field.

2.6 Performing Electrostatic Discharge and Antistatic Prevention Measures

2.6.1 Electrostatic Discharge Safety Measures

Electrostatic discharge (ESD) sensitive devices, such as the motherboards, drives, and memory DIMMs, require special handling.

Caution - Circuit boards and drives contain electronic components that are extremely sensitive to static electricity. Ordinary amounts of static electricity from clothing or the work environment can destroy the components located on these boards. Do not touch the components along their connector edges.

2.6.1.1 Using an Antistatic Wrist Strap

Wear an antistatic wrist strap and use an antistatic mat when handling components such as hard drive assemblies, circuit boards, or PCI 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 Blade X6275 server module. However, antistatic wrist straps are included with options.

2.6.1.2 Using an Antistatic Mat

Place ESD-sensitive components such as motherboards, memory, and other PCBs on an antistatic mat.

2.6.2 ESD Handling Procedure

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:

Antistatic bag used to wrap a Sun replacement part

Sun ESD mat, part number 250-1088

A disposable ESD mat (shipped with some replacement parts or optional system components)

2. Attach an antistatic wrist strap.

When servicing or removing server module components, attach an antistatic strap to your wrist and then to a metal area on the chassis.
