3 MV-801 Hardware Installation
3.1 Introduction
This section describes the installation of the MV-801 Integrated Multiviewer hardware.
Installation can be carried out while the Sirius 800 router is operating, without impacting the
main routing function.
MV-801 installation into a Sirius router also requires a Sirius 800 Multiviewer Crosspoint
module (5902) fitted in the router frame. The 5902 module is described in the
Sirius 800 User
Manual .
If the MV-801 is being fitted to an existing, installed router, then the router frame’s module
slots for the MV-801 hardware must be identified. Slot identification is part of the MV-801
hardware installation instructions contained in this section.
An MV-801 Quick Setup Guide is shipped with the module and is also available as a download
from Grass Valley.
MV-801 hardware installation comprises the following steps:
1 Initial Checks and Actions , on page 22.
2 Identifying Modules and Slots in the Sirius Router , on page 24.
3 Removal Preliminaries , on page 32.
4 Module Removal Procedure , on page 33.
5 Fitting Preliminaries , on page 34.
6 Connecting Cables , on page 38.
The following sections describe these installation steps. More than one MV-801 unit may be
fitted to a Sirius router and these instructions cover the fitting of one or more units.
The router may already have some options installed in the module slots required for the
MV-801 option. These installation instructions do not assume the presence or absence of any
particular option modules already in the router.
The Sirius 800 router controller software version installed on the router must support the
MV-801 Integrated Multiviewer option. Upgrading the Sirius 800 router controller software, if
required, can be carried out either before or after the MV-801 hardware installation.
Note: If your Sirius 800 router has been purchased from Grass Valley with the
MV-801 Integrated Multiviewer option already fitted, then

the MV-801 hardware installation task just comprises making
connections to the MV-801 Rear Panel at the rear of the router

(See Connecting Cables , on page 38).
CAUTION

Electrostatic Damage
Static precautions must be observed when handling,
inserting or removing modules.
