38 TNMC Troubleshooting & Maintenance
Front Access
1. Use a Philips screwdriver to remove the four
screws securing the module face panel to the
TNMC cabinet (
Figure 29 ).
2. Carefully remove the module from the face of
the message center.
Note: Do not hang the module by its
power/signal cable!
Rear Access
1. To access the internal components from the rear, remove the appropriate rear-access
panel from the TNMC by loosening the three bottom screws.
2. Slide the access panel up to the larger part of the keyhole and carefully lift it out and
then down away from the TNMC cabinet.
Note: Be careful when removing and handling the access panels as internal TNMC
components may still be attached to them.
The TNMC driver will always be located behind the first access panel on the right, along with
one power supply assembly. An additional power supply assembly is located behind each of
the other two access panels. Refer to
Figure 30 .
