3.4 Removal and then Fitting of Modules
This section covers the removal of any existing modules from relevant slots in the router frame
and then the fitting of modules for the MV-801 option.
Modules may be fitted while the router is powered up.
3.4.1 Removal Preliminaries
Some warnings and points of note are provided below: The following removal and fitting
procedures is designed to comply with these points.
Read through the following installation steps and notes to ensure that you understand them
before installing the MV-801 option.
Prepare all required modules, rear panels and other components.
CAUTION Ensure both of the
front and rear slots
in the router frame are
first empty
before inserting the FGAMV MV-801 main module
or Rear Panel.
This is because:
• The MV-801 front Main Modules must not be accidentally
connected to any other rear panels already fitted in the router
frame.
• The Rear Panels must not be accidentally connected to any
other front modules already fitted in the front of the router
frame.
Thus, these instructions are deliberately written in two stages:
• Removal. (See
•
Then
fitting. (See
This avoids any interim incompatibility between front and rear
modules during fitting, which may damage the modules and the
router.
Note:
Fit the 1312 MV-800/MV-801 Rear Panel(s) before fitting the front
MV-801 main module(s).
Note:
The fan door assemblies should be returned to the closed position as
soon as possible after opening. This ensures correct ventilation and
operation of the router frame.
In practice:
• Maximum time that a fan door may be left open will depend
on a number of factors, such as: ambient temperature, router
frame loading, crosspoint routing, etc.
• To ensure correct operation under all conditions the fan
assemblies should be left open for no more than 2 minutes at
a time.
• Take care not to trap any cables when opening and closing
the fan doors.
To minimize the time that router frame doors and fan doors are
open, ensure that you understand which modules need to be
changed and where they are located:
Table 10 gives the
before
and
after
module configuration.
