ule and the power outlet, the endpoint device is expected to
operate properly during steady-state conditions.
If the meter reads 1 volt or more, a ground loop problem ex-
ists that may cause data errors or equipment damage. To cor-
rect this condition, eectively bond the power sources together
to the same grounding electrode system.
In summary, it is essential to implement proper structured
grounding throughout a shielded cabling system to maxi-
mize equipment uptime, maintain system performance, and
protect expensive equipment. is is important for all shield-
ed cabling systems, including Category 6A, due to the in-
creased use of this cable type for 10GBase-T transmission.
e main advantage of using a shielded Category 6A cabling
system for 10GBase-T applications is the dramatic suppres-
sion of alien crosstalk; the containment of this noise helps en-
sure better signal integrity than can be achieved with a UTP
cabling system.
But the grounding and bonding requirements of Cat-
egory 6A shielded cables are more stringent. At the da-
ta center end of the structured cabling channels, these
requirements include proper bonding of the shielding to the
jack, proper grounding of the jack panels, and proper deploy-
ment of the grounding and bonding infrastructure within the
computer room and building. At the workstation, it is impor-
tant that the outlet ground is at the same potential as the tele-
communications ground.
Grounded for performance
e grounding and bonding system is more than an insurance
policy against a lightning strike. It is an active, functioning
system that provides protection for personnel and equipment
by minimizing the detrimental eects of electrical surges and
transient voltages.
By following standard principles and best installation
practices, your bonding and grounding system is a crit-
ical enabler of high-performance shielded structured ca-
bling solutions to improve network reliability and achieve
maximum 10GBase-T performance.
