Replacing Cold-Swappable FRUs |
This chapter describes how to remove and replace field-replaceable units (FRUs) in the server that must be cold-swapped.
The following topics are covered:
For a list of FRUs, see Appendix A.
Before you can remove and replace parts that are inside the server, you must perform the following procedures:
Note - These procedures do not apply to the hot-pluggable and hot-swappable devices (fans, power supplies, hard drives, and rear blower) described in Chapter 4. |
The corresponding procedures that you perform when maintenance is complete are described in Section 5.3, Common Procedures for Finishing Up.
The server can be serviced with the following tools:
Performing a graceful shutdown ensures that all of your data is saved and the system is ready for restart.
1. Log in as superuser or equivalent.
Depending on the nature of the problem, you might want to view the system status, the log files, or run diagnostics before you shut down the system. Refer to the Sun SPARC Enterprise T2000 Server Administration Guide for log file information.
Refer to your Solaris system administration documentation for additional information.
3. Save any open files and quit all running programs.
Refer to your application documentation for specific information on these processes.
Refer to the Solaris system administration documentation for additional information.
5. Switch from the system console to the ALOM CMT sc> prompt by typing the #. (Hash-Period) key sequence.
d. At the ALOM CMT sc> prompt, issue the poweroff command.
Refer to the Advanced Lights Out Management (ALOM) CMT Guide for more information about the ALOM CMT poweroff command.
If the server is installed in a rack with the extendable slide rails that were supplied with the server, use this procedure to extend the server to the maintenance position.
Note - Remove the server from the rack for all cold-swappable FRU replacement procedures except the DIMMs, PCI cards, and the system controller. |
1. (Optional) Issue the following command from the ALOM CMT sc> prompt to locate the system that requires maintenance.
Once you have located the server, press the Locator LED button to turn it off.
2. Check to see that no cables will be damaged or interfere when the server is extended.
Although the cable management arm (CMA) that is supplied with the server is hinged to accommodate extending the server, ensure that all cables and cords are capable of extending.
3. From the front of the server, release the slide rail latches on each side.
Pinch the green latches as shown in FIGURE 5-1.
4. While pinching the release latches, slowly pull the server forward until the slide rails latch.
Remove the server from the rack for all cold-swappable FRU replacement procedures except the DIMMs, PCI cards, and the system controller.
Caution - The serverweighs approximately 40 lb. (18 kg). Two people are required to dismount and carry the chassis. |
1. Disconnect all the cables and power cords from the server.
2. Extend the server to the maintenance position as described in Section 5.1.3, Extending the Server to the Maintenance Position.
3. Press the metal lever (FIGURE 5-2) that is located on the inner side of the rail to disconnect the CMA from the rail assembly (on the right side from the back of the rack).
This action leaves the CMA still attached to the cabinet, but the server chassis is now disconnected from the CMA.
Caution - The server weighs approximately 40 lb. (18 kg). The next step requires two people to dismount and carry the chassis. |
4. From the front of the server, pull the release tabs forward and pull the server forward until it is free of the rack rails.
The release tabs are located on each rail, about midway on the server.
5. Set the server on a sturdy work surface.
Caution - The system supplies standby power to the circuit boards even when the system is powered off. |
Disconnect both power cords from the power supplies.
Note - The following FRU replacements do not require that power be removed: DIMMs and PCI cards. |
1. Prepare an antistatic surface on which to set parts during removal and installation.
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. Do this after you disconnect the power cords from the server.
All field-replaceable units (FRUs) that are not hot-swappable require the removal of the top cover.
1. Press the top cover release button (FIGURE 5-3).
2. While pressing the top cover release button, slide the cover toward the rear of the server about half of an inch.
3. Lift the cover off the chassis.
