The S7902E, S7903E-S, S7903E, S7906E and S7910E switches provide chassis for horizontal cards. 

The fan tray is installed on the right side of the front of the chassis. The S7906E-V switch provides 

chassis for vertical cards. The fan tray is installed on the upper of the front of the chassis.

Over a long period of time, dust may block the air filter at the air intake vent of the S7900E series. As a 

result, the heat dissipation of the system may be affected. You are recommended to clean the air filter 

every three months. Air filters are optional accessories. 

Since the air flows up from the bottom, air filters for the S7906E-V, different from those for the other 

models, are installed on the front and rear sides near the bottom of the chassis.
