no precautions are required. Use one of the following installation methods while
performing an installation, when using more than four power cords:
◦ Using normal pluggable cords:
– Place the equipment in a restricted access area such as a locked closet or key card access room, the
access for which is granted only for qualified or service personnel.
– The building installation must provide a protective earth ground and a means for connection to the switch.
The service personnel must check whether the socket-outlet from which the switch is to be powered
provides a connection to the building protective earth. If not, the service personnel must arrange for the
installation of a protective earthing conductor, which shall be sized appropriately, from the grounding lug
terminal (as shown in the figure) to the protective earth wire in the building.
◦ Using industrial/locking pluggable cords:
– Secure at least one of the power cord connector ends on the switch power supply using the retention clip
provided on the 5400R 2750W PoE+ power supply as displayed in the figure. When you use this option,
the restricted access caution is not required.
