(Temperature: 10 to 35
Check the system clock once in a month. It is recommended to operate the system clock using a time server
(NTP server) if it is installed on the system which requires high level of time accuracy. If the system clock goes
out of alignment remarkably as time goes by, though the system clock adjustment is performed, contact your
sales agent.
When you store the equipment, keep it under storage environment conditions (Temperature: -10 to 55°C,
Humidity: 20 to 80%, non-condensing).
If NovaScale/ft Server series, the built-in optional devices, and the media set for the backup devices (tape
cartridges) are moved from a cold place to a warm place in a short time, condensation will occur and cause
malfunctions and breakdown when these are used in such state. In order to protect important stored data and
assets, make sure to wait for a sufficient period of time to use the server or components in the operating
environment.
Reference: Length of the time effective at avoiding condensation in winter (more than 10°C differences
between room temperature and atmospheric temperature)
Make sure that the optional devices are attachable and connectable to the equipment. There is a risk of
malfunctions that could lead to a breakdown of the equipment even if you could attach and connect.
Make sure that your options are compatible with the system. If you attach any incompatible option, there is a risk
of malfunction that could lead to a breakdown.
It is recommended to use Bull's genuine option products. Some competitors' products are compatible with this
server. However, servicing for trouble or damage resulting from such a product will be charged even within the
