Even if no PoE external power supply is installed, it is recommended that you 
reserve the PoE power supply slot (just cover a 4 U blank filler panel) in the 
cabinet for later PoE expansion.

■

For components of 4 U or higher, such as chassis and PoE power supply, more 
screws are required to secure the slide rails in the cabinet considering their 
weight.

■

You can adjust the specific height of every slot as needed. The following 
guideline is just for reference.
