2.6.1 ESD Guidelines
Media modules are equipped with electrostatically sensitive components.
These can be destroyed by the effect of an electric field or by charge
equalization when touching the printed circuit board or the contacts, or their
lifetime can be affected. Media modules are therefore delivered packed in a
conductive ESD protection bag. The packaging is reusable.
Make sure you adhere to the following protection measures for
electrostatically endangered assemblies:
Create electrical equipotential bonding between yourself and your
environment, e.g. using a wristband, which you clamp to the basic device
(knurled screw of an interface card). When the power supply cable is
connected, the basic device is grounded via the power supply connection.
Only now do you take the card out of the conductive bag.
Outside the basic device, only store the cards in a conductive ESD
protective bag.
ESD protective field equipment is available for the safe handling of
electrostatically endangered assemblies.
Further information about electrostatic sensitive modules can be found in
DIN EN 61340-5-1 (2007-08) and DIN EN 61340-5-2 (2007-08).

When using copper cables, provide a sufficient separation between the
power supply cables and the data cables. Ideally, install the cables in
separate cable channels.
Verify that power supply cables and data cables do not run parallel over
longer distances. To reduce inductive coupling, verify that the power
supply cables and data cables cross at a 90 ° angle.
Use shielded data cables for gigabit transmission via copper cables, for
example SF/UTP cables according to ISO/IEC 11801. To meet
EN 50121-4 and marine application requirements, use shielded data
cables at all transmission rates.
Connect the data cables according to your requirements.
