Site requirements
For proper K2 Lx0 Expansion Chassis operation, the installation site must conform to
certain environmental specifications. These are detailed below and in
Chapter 4, K2
Lx0 RAID Technical Specifications and Operating Limits .
Power
Refer to “Data handling specifications” on page 49 for AC power requirements. If one
of the two power supplies fails, the remaining power supply and cord can support the
full load. You must use a rack mount cabinet with AC power distribution, and have
main branch AC distribution that can handle these values for the number of K2 Lx0s
and K2 Lx0 Expansion Chassis units that you will interconnect.
Cooling
Make sure your site has air conditioning of the correct size and placement to maintain
the specified ambient temperature range. The air conditioning must be able to handle
the requirements of the K2 Lx0s and any connected K2 Lx0 Expansions as indicated
under
“Environmental limits” on page 50 .
Cabling requirements
It is recommended that you use the cables shipped with your K2 Lx0 RAID when
making connections. For cable specifications, refer to
“Cable lengths” on page 50 .
Host cables must meet the appropriate 4-Gbit HPA compliance standards.
NOTE: Also refer to the K2 Storage System Instruction Manual for cabling
diagrams and step-by-step instructions.
