QXS G2 Hardware Installation and Maintenance Guide
NOTE:
Although different drive modules and rear panel CRUs are used by the different chassis form
factors, whether used for RAID chassis or expansion chassis configuration, the RAID controllers and
expansion IOMs are common across 2U and 5U chassis.
Preparing for Installation
NOTE:
Chassis configurations:
•
2U RAID chassis are delivered without drives installed (RAID controllers and PSUs are installed).
•
2U expansion chassis are delivered without drives installed (expansion IOMs and PSUs are
installed).
•
5U RAID chassis are delivered:
• Without drives installed within the drawers.
• Drives ship in a 42-drive pack (two each 42-drive packs for a total of 84 drives).
• RAID controllers, fans, and PSUs are installed within the chassis.
•
5U expansion chassis are delivered:
• Without drives installed in the drawers.
• Drives ship in a 42-drive pack (two each 42-drive packs for a total of 84 drives).
• Expansion IOMs, fans, and PSUs are installed within the chassis.
CAUTION:
Lifting chassis:
•
A 2U chassis—together with all its component parts—is too heavy for one person to lift and install
into the rack cabinet. Two people are required to safely move a 2U chassis.
•
A 5U chassis—delivered without DDICs installed—requires four people to lift it from the box. A
suitable mechanical lift is required to hoist the chassis for positioning in the rack.
Make sure you wear an effective anti-static wrist or ankle strap and obey conventional ESD
precautions when touching modules and components. Do not touch midplane, motherboard, or
on page 165. This section provides important
preparation requirements and handling procedures for use during product installation.
