After fastening the main cabinet, open its front door to mount the CPU and PCI modules. For
details, see the following section "Installation of Rack-mount Model." Procedures are basically
the same for the tower model except that its modules are mounted vertically instead of horizontally.
IMPORTANT:
Follow the procedures below to install the CPU and PCI modules.
Note the followings before installing them.
Confirm the main cabinet is immobilized.
Place removed modules to the side of the system. Do not place modules on
top of the system.
It takes at least two people to mount the modules; mount them slowly and
carefully.
If you cannot install modules smoothly, remove them and try again.
Install the CPU modules in the left two slots, the PCI modules in the right two
slots.
Perform installation from the left slots.
