Step Action
2 Unbolt the VCE from its transport pallet.
3 Move the VCE to its final position in the equipment lineup and level the unit
by adjusting the levelling feet.
4 Connect the power cable to the 120 Vac 15 A power outlet.
Note: The power should be disconnected at the power supply breaker panel.
5 Connect the DV-45 equipment. See the application-specific documentation.
6 Put on an antistatic bracelet to protect the DV-45 cards.
7 Unpack all the DV-45 circuit packs.
8 Insert the cards in the DV-45 shelf (for a typical application, see Figure 1-2 on
page 1-3) but do not insert them into the backplane. That is, leave the latches
closed.
9 Check that the option switches on each card have been set correctly. The
correct settings are application specific (for example, see
DVLN Classroom
Site Equipment Installation , 323-1411-301, for the DVLN application).
10 Push the card into the backplane and close the latches on each card.
11 Install the locking bar when the last card has been installed.
12 Replace the VCE cover and the four cover-retaining screws.
