3.Make sure that mounting the SCSI Switch in a rack does not cause a hazardous condition because of uneven mechanical loading.

4.Make sure that adding the switch doesn’t overload the rack’s power circuit.

5.Make sure the power connections of the switch and the other equipment in your rack are properly grounded.
