If the chassis midplane or rear indicator module (RIM) fails, you will need to replace the I/O chassis. The I/O chassis is a Field-Replaceable Unit (FRU); only authorized Sun service providers should remove or install the I/O chassis.
You will need a Phillips No. 2 screwdriver to remove the I/O chassis. A magnetic tip screwdriver with a long shaft is recommended.
Power off the system chassis.
Remove all cables from the rear of the system.
Identify each cable, using tape or some other method, so that the system can be recabled easily when repopulating the system.
Disconnect all power supplies from the midplane by pulling each supply out of the chassis at least 1 inch (2.5 cm).
See the power supply removal steps in Replace Power Supply (Sun Blade 8000 Chassis) or Replace Power Supply (Sun Blade 8000 P Chassis).
Disconnect all Sun Blade Server Modules (blades) from the midplane by pulling each blade out from the chassis at least 1 inch (2.5 cm).
See the blade removal steps in Replace Blade.
For the Sun Blade 8000 Chassis, remove all PCI Express ExpressModules or their filler panels.
See the EM removal steps in Replace ExpressModule (Sun Blade 8000 Chassis).
Remove all Network Express Modules, or their filler panels.
See the NEM removal steps in Replace Network Express Module.
Remove the Chassis Monitoring Module(s), or their filler panels.
See the CMM removal steps in Replace Chassis Monitoring Module.
Locate and remove (using a magnetic tip, long shaft Phillips screwdriver) the Phillips screws securing the I/O chassis to the midplane. Use caution not to drop the screws into the chassis.
In the Sun Blade 8000 Chassis, there are four screws total to remove, two screws on each side of the I/O chassis.
In the Sun Blade 8000 P Chassis, there are two screws total to remove, one screw on each side of the I/O chassis.
The following illustration shows the location and removal of the four screws in the Sun Blade 8000 Chassis.
Pull out the I/O chassis approximately 4 inches (10 cm), so that the chassis slides out easily.
For the Sun Blade 8000 Chassis, grab the horizontal bar inside the I/O chassis and pull out the I/O chassis.
For the Sun Blade 8000 P Chassis, grab the sides of the I/O chassis where the sides of the I/O chassis wrap around the outside of the system chassis and pull out the I/O chassis.
The following illustration shows the I/O chassis removal from a Sun Blade 8000 Chassis. The I/O chassis in the Sun Blade 8000 P Chassis is in a similar location, above the AC interface module.
Shift your hands to the top underside of the I/O chassis and pull out the chassis while it is supported vertically.
Installation of the I/O chassis is the reverse of this procedure. When you install the I/O chassis, support the weight of the chassis with two hands. To power on the system, see Power On System After Service.
