Figure3-5 Grounding the router through the PE wire of AC power supplies 

 

 

Grounding the router through the RTN wire of DC power 
supplies 

 

CAUTION: 

Make sure the RTN wire is grounded reliably when it is routed out from the DC power cabinet. 

 

If the router  is powered by a –48 VDC power supply and no grounding strip is available at the 
installation site, you can ground the router through the return (RTN) wire of the DC power supplies, 
as shown in 

Figure3-6
