Chapter 6: Removing and Replacing Customer-Replaceable Units
To insert a disk module, follow these steps:
1. Ensure that the system is powered off and unplugged.
2. If necessary, snap the handle to the open position so that it is centered, as shown in
Figure 6-10.
3. If you are adding a drive, remove the drive filler plate that covers the drive slot you
want to use.
4. Align the new disk module with the drive guide, as shown in Figure 6-9.
5. Gently but firmly slide the disk module on the guides over the pin. When the disk
module is all the way in, it snaps.
6. When the disk module is in all the way, snap the handle right to the closed position,
as shown in Figure 6-10. In the case of the system disk module, which is upside
down relative to the other drives, snap the handle left.
7. Use the packaging for the new disk module to repackage the old disk module.
Removing the Facade
The facade must be taken off before you can remove the System Controller and CD-ROM
assembly. Use these procedures to remove the facade:
1. Lift off the cable bales that hold the CrayLink and Xpress link cables in place.
2. Remove the CrayLink Interconnect and Xpress link cables from the Rack Router
board ports (as required).
Caution: Be sure that the connectors are labeled before you remove them, so that
you know where to replug them afterwards.
3. Remove the screw that secure the facade to the chassis (see Figure 6-11).
4. Lift up to disengage the facade from the chassis; then pull it straight out.
5. Reverse these steps to install the facade.
