the S7506R and the S7503 are fixed by captive screws, while the fan tray of the S7506
is fixed by two locks.
The following describes how to install and remove these two types of fan trays,
respectively.

If you want to replace the fan tray when the switch is working, separate the fan tray
from the backplane to disconnect the power and wait till 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.

may be broken.
