Checking the Airflow
•
Make sure there are no objects obstructing the airflow in and out of the chassis.
In addition, if you are using a front bezel, make sure the bezel's filter is replaced
periodically.
•
Except for brief periods while swapping hard drives, do not operate the server
without drives or the drive carriers in the drive bays. Use only recommended
server parts.
•
Make sure no wires or foreign objects obstruct airflow through the chassis. Pull
all excess cabling out of the airflow path or use shorter cables.
•
The control panel LEDs inform you of system status. See "Chapter 3: System
Interface" for details on the LEDs and the control panel buttons.
Installation Complete
In most cases, the chassis power supply and fans are pre-installed. If you need
to install fans or power supplies, continue to the Systems Fan and Power Supply
sections of this chapter. If the chassis will be installed into a rack, continue to the
next chapter for rack installation instructions.

System Fans
Four fans provide cooling for the chassis. These fans circulate air through the
chassis as a means of lowering the chassis internal temperature. The SC217 system
fans not hot-swappable. They are easy to change modules. There is no need to
uninstall any other parts inside the system when replacing fans, and no tools are
required for installation.
Optional Fan Configurations
The SC217H model chassis is designed so that the default configuration of the
system is for each motherboard to control two fans. The fans not hot-swappable.
Each motherboard node in the chassis is connected to the backplane through the
adapter card, mounted in the motherboard node drawer. In the event that one of
the motherboard drawers is removed, then the remaining motherboard will operate
both fans.
Fan Configurations Options
SC217H Hot-Swappable Default Configuration
Fans A and B connected to backplane,
backplane connected to Node A and B by adapter card
Fans C and D connected to backplane,
backplane connected to Nodes A and B by adapter card
