If the ground bar of the
network cabinet fails to
securely ground, ensure
that the fiber strength
member is disconnected
from the ground bar and
that the fiber strength
member is properly
insulated. Otherwise,
heavy currents may be
discharged using the
network ports on the local
and peer devices, which
may damage these
network ports.
