Network Deployment Overview
Network Deployment Overview
The deployment process for the SEL-FT50 and SEL-FR12 networks consists of
the following three phases:
➤ Research
➢ Installation site candidate selection
➢ Antenna selection
➢ Link budget estimation
➤ Planning
➢ Path study
➢ Area coverage study
➢ Channel selection
➤ Installation
➢ SEL-FR12 installation
➢ SEL-FR12 commissioning
➢ SEL-FT50 installation
➢ SEL-FT50 commissioning
➢ Optional SEL-RP50 installation
➢ Optional SEL-RP50 commissioning
Begin the network deployment process with the research and planning phases to
determine whether a reliable link can be established. If so, install and set up the
SEL-FR12 first so the SEL-FT50 devices join the SEL-FR12 network upon
installation. Consider the following guidelines before deploying an SEL-FT50/
SEL-FR12 system:
➤ Select SEL-FR12 and SEL-FT50 installation locations with a clear
line of sight (i.e., minimal path obstructions) for best network perfor-
mance.
➤ When obstructions limit line-of-sight, consider including SEL-RP50s
in the design. See Appendix D: SEL-RP50 Fault Repeater Detailed
Implementation on page 54.
➤ Perform a separate link budget estimation for every unique link on
the network (i.e., between the SEL-FR12 and each trio of collocated
SEL-FT50 devices, the link between SEL-FT50s and corresponding
SEL-RP50s, between sequential SEL-RP50 installations, and
between the SEL-RP50 and SEL-FR12.). See Appendix C: Link Bud-
get Analysis on page 48 for more information. See Appendix D:
SEL-RP50 Fault Repeater Detailed Implementation on page 54 when
considering the use of SEL-RP50 Fault Repeaters.
WARNING
Do not perform any procedures or adjustments that this instruction
manual does not describe.
AVERTISSEMENT
Ne pas appliquer une procédure ou un ajustement qui n’est pas décrit
explicitement dans ce manuel d’instruction.
CAUTION
Equipment components are sensitive to electrostatic discharge (ESD).
Undetectable permanent damage can result if you do not use proper
ESD procedures. Ground yourself, your work surface, and this equip-
ment before removing any cover from this equipment. If your facility is
not equipped to work with these components, contact SEL about
returning this device and related SEL equipment for service.
ATTENTION
Les composants de cet équipement sont sensibles aux décharges élec-
trostatiques (DES). Des dommages permanents non-décelables
peuvent résulter de l’absence de précautions contre les DES. Raccor-
dez-vous correctement à la terre, ainsi que la surface de travail et
l’appareil avant d’en retirer un panneau. Si vous n’êtes pas équipés
pour travailler avec ce type de composants, contacter SEL afin de
retourner l’appareil pour un service en usine.
