Hardware Upgrade and
Replacement Procedures
ClearCube’s architecture greatly simplifies complete computer upgrades as well as
upgrades to individual components. A complete PC Blade is easily upgraded by
lowering the Cage front bezel, slowly pulling out the old PC Blade, and then replacing
with a new PC Blade.
Individual components, including memory and hard drive, BackPacks, and fan packs
can also be upgraded or replaced by qualified technicians. These components are
accessible by removing the PC Blade from the Cage. Complete service procedures
can be found in the ClearCube Service Manual.
To maintain your ClearCube warranty and ensure proper operation, only use
ClearCube approved commodities when performing upgrades.
Customer Replaceable Units (CRUs) are items that the customer can replace onsite.
Field-Replaceable Units (FRUs) are items that trained service providers and the SE
group can replace onsite.
Customer Replaceable Units (CRUs) typically include:
• Memory
• Video card (if installed)
• IDE or SATA Hard disk drive (HDD)
• LCD assembly and cable
• IDE or SATA HDD cable
Field Replaceable Units (FRUs) are items that trained service providers and the SE
group can replace onsite. FRUs include the CRUs, plus these:

CAUTION: All upgrades should be performed by a qualified computer
technician. Take proper precautions to avoid damaging electrostatic
discharges by working at a grounded computer equipment repair bench.
Damage caused by improper upgrade procedures will void your warranty.
