4. Setup
This chapter describes the OLT system installation procedures.
4.1 Mechanical Packaging
Important!
When installing or servicing these GPON systems it is necessary to take into account the following aspects:
In a servicing system it is imperative that the access to any board or fan module, can be done without affecting the service
supported by other units;
The grids that exist in the steel structures which are used for entry and exit of air, should not be clogged up with the penalty
of affecting the correct functioning of the cooling system;
Once the connections and access to equipment interfaces are made, a distance of approximately 12cm in front of the
structure must be reserved, to accommodate the wiring.
It is imperative to follow all ESD precautions described in ESD , when accessing to the OLT system or handling any system
board or module.
It is imperative to disconnect all power source on the Disconnect Device before servicing the unit.
4.2 ESD Precautions
Important!
When performing OLT system service actions, observe the following electrostatic discharge (ESD) precautions:
Wear an antistatic wrist strip at all times when handling any system part, board or module.
Before handling any system part, board or module, discharge any static electricity by touching a grounded surface.
Remove all plastic, vinyl, and foam material from the work area.
Do not remove a system board or module from its antistatic protective bag until you are ready to install it.
After removing a board or module from the system chassis, immediately place it in an antistatic bag or antistatic packaging.
Handle any system board only by its edges and avoid touching the components or circuitry.
Do not slide a system board or module over any surface.
Limit body movement (which builds up static electricity) during the removal and replacement of a system board or module.
4.3 OLT Ref.769401 System
The OLT Ref.769401 system uses 1U / 19” ETSI infrastructure. Please see Figure 4-1.
