Water requirements
Water requirements
ThinkSystem SR630 V4 is supported in the following environment:
• Maximum pressure: 3 bars
• Water inlet temperature and flow rates:
Water inlet temperature Water flow rate
50°C (122°F) 1.5 liters per minute (lpm) per server
45°C (113°F) 1 liter per minute (lpm) per server
40°C (104°F) or lower 0.5 liters per minute (lpm) per server
Note: The water required to initially fill the system side cooling loop must be reasonably clean, bacteria-free water
(<100 CFU/ml) such as de-mineralized water, reverse osmosis water, de-ionized water, or distilled water. The water
must be filtered with an in-line 50 micron filter (approximately 288 mesh). The water must be treated with anti-
biological and anti-corrosion measures.
Particulate contamination
Attention: Airborne particulates (including metal flakes or particles) and reactive gases acting alone or in
combination with other environmental factors such as humidity or temperature might pose a risk to the
device that is described in this document.
Risks that are posed by the presence of excessive particulate levels or concentrations of harmful gases
include damage that might cause the device to malfunction or cease functioning altogether. This
specification sets forth limits for particulates and gases that are intended to avoid such damage. The limits
must not be viewed or used as definitive limits, because numerous factors, such as temperature or moisture
in the air, can influence the effect of particulates or environmental corrosives and gaseous contaminant
transfer. In the absence of specific limits that are set forth in this document, you must implement practices
that maintain particulate and gas levels that are consistent with the protection of human health and safety. If
Lenovo determines that the levels of particulates or gases in your environment have caused damage to the
device, Lenovo may condition provision of repair or replacement of devices or parts on implementation of
appropriate remedial measures to mitigate such environmental contamination. Implementation of such
remedial measures is a customer responsibility.
