ft)
10°C to 30°C (50°F to 86°F) with no direct sunlight on the equipment.
Thermal restrictions
•
System must operate at temperature below 30°C.
•
All fans installed in the system must be from the same manufacturer.
•
Fresh air condition is not supported.
•
Non Dell qualified or certified processors are not supported.
•
LRDIMM is not supported.
•
10 GbE / 25 GbE OCPs require PCIe shroud with rear drive configuration if there is no PCIe card installed.
•
Butterfly without riser configuration cannot support 10GbE / 25GbE OCP because PCIe shroud cannot be installed.
•
Drive bays should not be in service position for more than 5 minutes because of thermal concerns. When the drive bay is open for
more than five minutes, the cooling fans spin at a higher speed to provide extra cooling to the system. Thus system health status
changes from the normal to critical state, and system event
The BP1 drive bay is kept open for an extended
period of time
is logged.
•
GPGPU card is not supported.
•
Non Dell certified peripheral cards are not supported.
•
Expansion card and riser installation must follow specific Expansion card installation guidelines.
•
Mellanox CX-5 dual port 100G - QSPF PCIe adapter cable is restricted to Dell NW QSPF28 Direct attach cables and Finisar 100G 85C
optic cables. Non Dell certified cables are not supported.

Particulate and gaseous contamination specifications
The following table defines the limitations that help avoid any equipment damage or failure from particulates and gaseous contamination. If
the levels of particulates or gaseous pollution exceed the specified limitations and result in equipment damage or failure, you may need to
rectify the environmental conditions. Re-mediation of environmental conditions is the responsibility of the customer.

Air filtration
Data center air filtration as defined by ISO Class 8 per ISO 14644-1 with a
95% upper confidence limit.
NOTE:
This condition applies to data center environments only.
Air filtration requirements do not apply to IT equipment designed
to be used outside a data center, in environments such as an
office or factory floor.
NOTE:
Air entering the data center must have MERV11 or
MERV13 filtration.
