•
Before installing or removing any module, ensure that the installation or the removal
does not violate the rules specified in “Installation Rules for the 100G Coherent CFP”
on page 177. This applies even if the module you are installing or removing does not
contain a 100G Coherent CFP transceiver.
•
Before installing a module, ensure that the slot is free from dust and other debris.
•
All empty slots should be covered with filler panels. This prevents debris from getting
into the slot, and helps maintain the required system temperature.
•
Module installation is independent of module configuration. You can configure a module
and then install it, or you can install a module and then configure it. For details on
configuring modules (including pre-provisioning and autoprovisioning), see the BTI7800
Series Software Configuration Guide.
•
Visually inspect the module, including the pins and connectors that attach to the
backplane, for signs of damage before installation.
•
Always install one module at a time. If the module is correctly installed, the faceplate
will be in line with other installed modules and the latches will be secured correctly.
•
The thumbscrews used to secure the module can be operated by hand or with a
screwdriver.
•
Ensure protective covers are placed on all unused ports.
•
Be familiar with the module LED indicators described in “Service Module LEDs” on
page 151.
Safety Warnings
•
This equipment is intended to be installed and serviced by qualified personnel.
•
Be familiar with the safety guidelines described in the BTI7800 Series Hardware Overview
and Installation Guide.
•
Ensure the chassis is installed properly and secured onto the rack.
•
Ensure you have an unobstructed path to the chassis.
•
Avoid contact with rotating fan blades.
Electrical Warnings
CAUTION: Electrostatic Discharge (ESD) can damage module components,
causing complete or intermittent failures. ESD can occur when a module is
improperly handled.
To prevent ESD damage to a module, follow these guidelines:
•
Always wear an ESD grounding device, such as an ESD wrist strap, when handling a
module.
•
Do not remove a module from its antistatic bag until installation. Store removed
modules in antistatic packaging.
