2.3 Prerequisite Tasks for Component Replacement
Before you can remove and install components that are inside the server, you must
perform the following procedures:
Power Off the Server
Performing a graceful shutdown makes sure all of your data is saved and
the system is ready for restart.
- 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 server administration guide for log file information.
- Notify affected users.
Refer to your Solaris system administration documentation for additional information.
- Save any open files and quit all running programs.
Refer to your application documentation for specific information on these processes.
- Shut down the Solaris OS.
Refer to the Solaris system administration documentation for additional information.
- Switch from the system console to the ALOM CMT compatibility CLI sc> prompt by
typing the #. (Hash-Period) key sequence.
- At the ALOM CMT compatibility CLI sc> prompt, issue the poweroff command.
sc> poweroff -fy
SC Alert: SC Request to Power Off Host Immediately.
Note - You can also use the Power button on the front of the server
to initiate a graceful system shutdown. This button is recessed to prevent accidental
server power-off. Use the tip of a pen to operate this button.
Refer to the Integrated Lights Out Manager (ILOM) Administration Guide for more information about the ALOM CMT CLI poweroff
- Disconnect the cables from the server.
See Disconnect Cables From the Server.
Disconnect Cables From the Server
Caution - The system supplies standby power to the circuit boards even when the system
is powered off.
- Label all cables connected to the server.
- Disconnect the following cables as appropriate:
- PCI or XAUI cards
- Alarm board
- TTYA serial port
- Serial management port
- Network management port
- USB ports
- Ethernet ports
- Power supplies
- If you are going to remove the CMA, also remove the cables from
- Remove the server from the rack.
Remove the Server From the Rack
Remove the server from the rack prior to performing cold-swappable FRU replacement procedures
except the FB-DIMMs, PCI cards, and the service processor.
Caution - The server weighs approximately 80 lb (36 kg). Two people are required to
dismount and carry the chassis.
- Disconnect all the cables and power cords from the server.
- From the front of the server, release the slide rail latches or remove the
necessary hardmount screws, depending on you rack type.
- Set the server on a sturdy work surface.
Caution - Do not attempt to open the front bezel while the bezel is resting
on a flat surface. Doing so results in damage to the bezel hinges
on either side.
- Perform antistatic measures.
See Perform Antistatic Measures.
Perform Antistatic Measures
- 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:
- Antistatic bag used to wrap a Sun replacement part
- Sun ESD mat, part number 250-1088
- Disposable ESD mat (shipped with some replacement parts or optional system components)
- 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. Then disconnect the power
cords from the server.
- Remove the top cover.
See Remove the Top Cover.
Remove the Top Cover
All field-replaceable units (FRUs) that are not hot-swappable require the removal of the
- Use a No. 2 Philips screwdriver and loosen the two green captive screws
securing the top cover on the rear of the server (Top Cover and Release Button).

- Slide the cover toward the rear of the server.
- Lift the cover off the chassis and set it aside.
