Converting the TR6442i Viper II Rack Mount Unit
Fig. A-8: Removing back panel screws
Note the two tabs that go into the bottom plate of the unit.
9 Once the screws are removed, pull the connector board up and away from the unit.
Make sure to not bend the ribbon connector. Set aside for re-installation.
10 On the main circuit board, loosen but DO NOT REMOVE the two screws indicated. This
will allow you to raise slightly the board and allows the rear panel to come clear of the
main unit.
Fig. A-9: Removing the rear panel
Note the tabs/slots on the bottom of the unit. These tabs/slots are what you will be
clearing in order to remove the rear panel.
11 Lift the front panel slightly and pull out away from the unit. Make sure to clear the tabs.
The previous step of loosening the circuit board screws should give you the clearance
to remove the rear panel. If it does not feel free, completely remove the screws and
retain them for re-installation.
