1. Remove power from the Coral system.
Verify that all the PS19 units in the system are turned OFF (downwards).
2. Connect the static dissipating wrist strap connector to the cage and wear the strap.
3. Verify that all control and peripheral cards in the main cage and expansion cages
protrude from the cage by approximately 1 inch (2.5 cm).
4. Remove the MEX-IP2 card from its slot and place it on a static protective surface.
5. Verify that the DBM/DBX or MAP/CLA baby cards are not attached to MEX-IP2
interface connectors P1, P2 or P3. See
Figure 3-2
for the location of the memory
interface connectors. See
Figure 3-4 and Figure 3-5
for the MAP/CLA and
DBM/DBX cards.
If installed, remove the MAP/CLA and or the DBM/DBX baby cards, as described
on
page 8-1, Common Control Cards

Coral circuit cards contain static-sensitive circuitry that could be damaged or destroyed
by electro-static discharge (ESD).
Always wear the static dissipating wrist strap connected to the cage while handling the
circuit cards. See Figure 2-17 on page 2-30 .
Hold circuit cards by their edges to avoid touching contact surfaces.
1 Control Card Initialization
Inserting or removing the MEX-IP2 card into a cage that has been powered will damage
the card. Verify that the power supply unit is switched OFF before inserting the
MEX-IP2.
