avoid injury. 

If you want to replace the fan tray of an in-service switch, separate the fan tray from the backplane to 

disconnect the power and wait for the fan stops rotating before pulling it out completely. Considering 

that the fan may be still rotating, avoid stretching your hands into the fan tray. 

 

The fan tray handle of the S7906E-V is slightly different from those of the S7902E, S7903E-S, S7903E, 

S7906E, and S7910E. The fan tray handles of S7902E, S7903E-S, S7903E, S7906E, and S7910E are 

fixed, while that of the S7906E-V is hidden in the groove of the fan tray. Therefore, you need to rotate 

the handle out of the groove before removing the fan tray from the S7906E-V or installing a fan tray on 

the S7906E-V.
