SC825M Chassis Manual

5-12

5-7  Checking the System Air Flow

Proper airflow allows the chassis to keep the server components cooled and prevent 
damage.  Use  the  following  steps  to  check  airflow  after  setup  and  in  the  unlikely 
event the chassis needs to be serviced.

Checking the Server's Air Flow

Make sure no cables or foreign objects obstruct air flow through the chassis. 
Pull all excess cabling out of the airflow path or use shorter cables. For the 
825M chassis it is recommended that cables run beside the power supply as 
much as possible.

Make sure there are no objects to obstruct airflow in and out of the server. 

Do not operate the server without hard drives or dummy drives in the hard 
drive trays.

Use recommended server parts only.

The control panel LEDs inform you of system status. See “Chapter 3: System 
Interface” for details on the LEDs and the control panel buttons.
