CAUTION:
■ 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.
