Removal and then Fitting of Modules
This section covers:
• removal of any existing modules from relevant slots in the router frame;
• the fitting of a MV-831 module. Modules may be fitted while the router is powered up.
Removal Preliminaries
Some warnings and points of note are provided below: The following removal and fitting
procedures are designed to comply with these points.
Prepare all required modules, rear panels and other components.
Before fitting a MV-831 module, the relevant front and rear module slots need to be emptied
first before fitting the MV-831 option hardware.
These instructions are deliberately written in two stages:
1 Removal. (See Module Removal Procedure on page 46.)
2 Then fitting. (See Fitting Preliminaries on page 48.)
This avoids any interim incompatibility between different front and rear modules during
fitting, which may damage modules and the router.
Note: A MV-831 comprises a double-width front module and rear panel.

Thus MV-831 occupies the following Sirius 830 router slots:
• A pair of front input-output module slots. (Slot numbers 1-2,
3-4, etc)
• A pair of corresponding rear output slots.
CAUTION

Ensure both of the front and corresponding rear slots in the
router frame are first empty before inserting the MV-831
Main Module and/or MV-831 rear panel (MV-830-RP).
This is because:
– MV-831 front Main Modules must not be accidentally
connected to any other rear panels already fitted in the
router frame.
– MV-831 Rear Panels must not be accidentally connected
to any other front modules already fitted in the front of
the router frame.
WARNING

Handle and fit with care, the MV-830-RP Rear Panel has some sharp,
pointed locating pins.
