3.2  Before You Begin 
Confirm the following requirements before installation:   
  The installation site provides sufficient space for heat dissipation.   
  The installation site meets the temperature and humidity requirements of the switch. 
  The power supply and required current are available in the installation site.   
  The Ethernet cables have been deployed in the installation site.   
3.3  Mounting the Switch 
Notes 
  Connect the power cords of different colors to the corresponding grounding posts.   
  Ensure the power cords are securely connected.   
  Do not place heavy objects on the switch. 
  Maintain a minimum clearance of 100 mm (3.94 in.) around the device for air circulation. 
  Keep the switch away from high-power radio stations, radar stations, and high-frequency high-current devices. Use EMI shielding 
such as shielded interface cables to minimize interference when necessary. 
  Route  interface  cables  only  indoors  to  prevent  signal  ports  from  getting  damaged  by  overvoltage  or  overcurrent  caused  by 
lightning strikes. 
3.3.1  Mounting the Switch in a Rack 
All models of the RG-S5300-E and RG-S5310-E series switches can be installed in a standard 19-in. four-post EIA rack. Mount the switch 
in the rack with the front panel face forward.   
1.  Use a Phillips-head screw driver to secure a bracket to each side of the switch with two screws.

2.  Install two cage nuts on the inside of each front rack and drive the screws halfway into the cage nuts.
