"grounded port" for ethernet:
from: http://support.3com.com/documents/switches/baseline/3Com-Switch-Family_Safety-Reg-Info.pdf
"CAUTION: If you want to install the Switch using a Category 5E or
Category 6 cable, 3Com recommends that you briefly connect the cable
to a grounded port before you connect to the network equipment. If you
do not, the cable’s electrostatic discharge (ESD) may damage the Switch's
port.
You can create a grounded port by connecting all wires at one end of a UTP cable to an earth ground point, and the other end to a female RJ-45 connector located, for example, on a Switch rack or patch panel. The RJ-45 connector is now a grounded port."
