Communication Server 1000E Installation and Commissioning
2 Connect the NTDU6201 Ground Bar to the ground bus in the AC electrical
panel, or to TGB for an ANSI/EIA/TIA 607 installation using #6 AWG wire.
See Table 12 on
page 93 for region-specific grounding requirements.
3 Place a tag marked DO NOT DISCONNECT on the ground wire at the
electrical panel.
4 Test the ground.
End of Procedure
Grounding an ISP1100 Signaling Server
The ISP1100 Signaling Server is not connected to a ground bar. It is properly
grounded when:
• the ISP1100 Signaling Server power cord is plugged into the rack’s AC
outlet. The rack’s AC outlet must be grounded to its dedicated electrical
panel. This is the preferred method.
• the ISP1100 Signaling Server power cord is plugged into a wall AC
outlet. The ISP1100 Signaling Server is grounded outside of the rack
using the safety grounding conductor in the power cord. This method
ensures proper grounding only of the ISP1100 Signaling Server itself. It
does not provide grounding protection for other rack-mounted pieces of
equipment. Therefore, ensure that other devices in the rack are properly
grounded as required.
Grounding a Media Gateway powered by the
same electrical panel
Follow Procedure 5 to ground one or more Media Gateway powered by the
same electrical panel.
WARNING
A qualified technician or electrician must make the
connection in the AC electrical panel.
