Network Safety
This subclause sets forth a number of recommendations and guidelines related to safety concerns. The list is
neither complete nor does it address all possible safety issues. The designer is urged to consult the relevant
local, national, and international safety regulations to verify compliance with the appropriate requirements. LAN
cabling systems described in this clause are subject to at least four direct electrical safety hazards during their
installation and use. These hazards are as follows:
a) Direct contact between LAN components and power, lighting, or communications circuits.
b) Static charge buildup on LAN cabling and components.
c) High-energy transients coupled onto the LAN cabling system.
d) Voltage potential differences between safety grounds to which various LAN components are connected.
Such safety hazards should be avoided or appropriately protected against for proper network installation and
performance. In addition to provisions for proper handling of these conditions in an operational system, special
measures should be taken to verify that the intended safety features are not negated during installation of a
new network or during modification of an existing network.
Installation and Maintenance Guidelines
From IEEE Approved Draft P802.3bt/D3.7 Sept 2018 145.6.3: It is a mandatory requirement that sound
installation practice, as defined by local codes and regulations, be followed in every instance in which such
practice is applicable. In particular, users are cautioned to be aware of the ampacity of cabling, as installed, and
local codes and regulations, e.g., ANSI/NFPA 70 – National Electric Code® (NEC®), relevant to the maximum class
supported.
It is a mandatory requirement that, during installation of the cabling plant, care be taken to verify that non-
insulated network cabling conductors do not make electrical contact with unintended conductors or ground.
Patch Panel Considerations
It is possible that the current carrying capability of a cabling cross-connect may be exceeded by a PSE.
The designer should consult the manufacturer's specifications to verify compliance with the appropriate
requirements.
Electromagnetic Emissions
The PD and PSE powered cabling link shall comply with applicable local and national codes for the limitation of
electromagnetic interference.
Temperature and Humidity
The PD and PSE powered cabling link segment is expected to operate over a reasonable range of environmental
conditions related to temperature, humidity, and physical handling. Specific requirements and values for these
parameters are beyond the scope of the standard.
