Follow these steps to remove the fan tray of other models: 

1)  Wear an ESD-preventive wrist strap and loosen the captive screws on the fan tray with a 

screwdriver (see callout ① in 

2)  Drag the fan tray out of the slot (see callout 

 

② in 

3)  Put the removed fan tray into a package. 

Install a fan tray in the opposite way you remove it: 

1)  Take a new fan tray out of a package and slide it along the guide rails into the switch until it snaps 

into the chassis backplane. 

2)  Tighten the captive screws on the fan tray with a screwdriver. 

To facilitate installation and cable routing, mounting ears and a cabling rack are shipped together with 

the S7900E series, but they are separated. Therefore, you first need to install the cabling rack on a 

mounting ear. 

For the S7906E-V, it is unnecessary to install cabling racks onto mounting ears. Two cabling racks are 

provided for the S7906E-V: upward cabling rack and downward cabling rack. These two cabling racks 

are different. The cabling rack with a tray should be installed in the lower part of the chassis. However, 

they are installed in the same way. 

The mounting ears of the S7900E series are installed in the same way.
