The outer pair of DIMM slots must always be populated. The modules used in the
inner pair do not have to match the modules used in the outer pair, just within each
pair.
NOTE: Because of a limitation in 32-bit Microsoft Windows, the operating system
reports and utilizes no more than 3 GB of memory when 4 GB of memory is
installed.
Always use ClearCube-supplied or ClearCube-approved memory.
Replacing or Upgrading the Hard Drive
If you are replacing or upgrading a hard drive, do the following:
1. Remove the blade from the chassis.
2. Remove the 3 screws (R1300) or 4 screws (R2200) that attach the hard drive to
the PC blade frame.
3. Disconnect the SATA and power cables from the hard drive, making sure to note
the proper orientation of the cables for later reassembly.
4. Install the new hard drive in the reverse order of disassembly, making sure to
reconnect the cables in the proper orientation.
5. Replace the blade in the chassis.
6. Power up the blade.
7. Reinstall the operating system and application software.
These considerations should be observed:
• Hard drive mechanisms are very sensitive to mechanical shock, and are most
vulnerable when handled as an unmounted unit. Handle them gently, especially
when setting them down on a work surface.
• Drive cables should be removed by pulling on the connector, not the cable. Pull
the connector straight out, not at an angle.

CAUTION: Some surfaces on the blade may be hot, especially when the
blade has been powered on. Remove and handle the blade with care.
