Follow these recommendations for copper data cabling in high electrical noise 
environments: 
 
  Data cable lengths should be as short as possible - ideally limited to 3m (10ft) 
in length. Copper data cables should not be used for inter-building 
communications. 
  Power and data cables should not be run in parallel for long distances, and 
ideally should be installed in separate conduits. Power and data cables 
should intersect at 90
 angles when necessary to reduce inductive coupling. 
  Shielded/screened cabling can optionally be used. The cable shield should 
be grounded at one single point to avoid the generation of ground loops. 
 
2.7.3  Transient Suppression 
RuggedCom does not recommend the use of copper cabling of any length for 
critical, real-time, substation automation applications. However, transient 
suppression circuitry is present on all copper ports to protect against damage 
from electrical transients and to ensure IEC 61850-3 and IEEE 1613 Class 1 
conformance. This means that during the transient event, communications errors 
or interruptions may occur but recovery is automatic. RuggedCom also does not 
recommend using these ports to interface to field devices across distances which 
could produce high levels of ground potential rise, (i.e. greater than 2500V) 
during line-to-ground fault conditions. 
2.8  Pluggable optics – Installation, removal, and 
precautions 
The RSG2200 series of products can be ordered with pluggable optic form 
factors: SFP (Small Form-factor Pluggable) or GBIC (Gigabit Interface 
Converter). SFP and GBIC modules can be safely inserted and removed while 
the chassis is powered and operating – this feature is also known as “hot-
swappable”. When inserting or removing optics, there are several precautions 
that should be taken. They include: 
 
  Ensuring that dust caps are mounted on SFP cages at all times unless a user 
is in the process of inserting or removing an SFP module. The dust caps will
