Site requirements
For proper K2 Level 3 Expansion Chassis operation, the installation site must
conform to certain environmental specifications. These are detailed below and in
Chapter 4, Level 3 RAID Technical Specifications and Operating Limits .
Power
Refer to “Data handling specifications” on page 55 for AC power requirements. The
values indicate either the values for the power cord of a K2 Level 3 Expansion Chassis
with a single power supply, or the total values shared by the line cords of two power
supplies in the same K2 Level 3 Expansion Chassis, with the division between the
power cords and supplies at the current sharing ratio. If one of the two power supplies
fails, the remaining supply and cord must 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 Level 3s and K2 Level 3 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 Level 3s and any connected Level 3 Expansions as
indicated under
“Environmental limits” on page 56 .
