■ Store the unit under the approved storage conditions (temperature: -10°C - 55°C, humidity:
20% - 80%, without condensation) to allow the built-in devices and the unit to operate
correctly in the next operation.
■ If the server is stored under the environmental condition enduring device operation
(temperature: 10°C - 35°C *1 , humidity: 10% - 80%), leave the server in the operating
environment at least one hour before turning the AC power on.
■ If the media (e.g., tape cartridge) brought from a cold place to a warm place suddenly is set
in the server, internal option device, or the backup device, the dew condensation may be
generated resulting in malfunction or failure of the unit. Leave the media in the operating
environment until it fully adapts to the surroundings to protect the valuable data or property.
Guideline to eliminate dew condensation in winter time (10 degrees or more temperature
difference from the room temperature exists):
Disk drive: Two or three hours (approx.)
Media: One day (approx.)
■ NEC recommends you use NEC's genuine products. Some third-party products claim that
they support the server. However, repair of the server due to a failure or damage resulted
from use of such third-party products will be charged.
■ Turn off the cellular phone or pager. Radio interference may cause malfunctions of the
server.
*1 It is possible to use the server under 40°C when the server applies the BMCFW and BIOS
supporting the condition and does not have HDD#1,#4,#7,#10,SAS RAID BBU and external
SAS RAID controller. If any HDD is mounted on those slots, replace it with "Disk Dummy
Tray", NE3105-901.
Also refer to "1.4.6 Mode Settings" and set Maximum AmbientTemperature as 40
degrees C to use under 40°C.
The servers shipped after March in 2012 apply the BMCFW and BIOS by default.
Consult with maintenance personnel of the maintenance service company for applying the
required BMCFW and BIOS to the server if necessary.
