EMC grounding clip
Option 11C and Option 11C Mini Main cabinets connected with 100BaseT
IP connectivity, must route the cables though the EMC grounding clip. This
ensures electrical contact between the ground rail and 100BaseT cable for
EMC containment
The NTDK41AA EMC grounding clip is used on the Option 11C system on
each IP Expansion cabinet.
