5.5 Installation

To install the ASM-20/R card in the ASM-MN-214 card cage:

1. Install the ASM-MN-214 card cage in the 19" rack.

2. Adjust the jumpers and switches on the card as required (see Table 2-1

and Figure 2-3 in Chapter 2).

3. Insert the ASM-20/R card into one of the ASM-MN-214 slots. Push the

bottom of the card into the cage to until it is fully inserted into the edge

connector inside the rack. Tighten the screws on the top and on the

bottom of each card.

4. Remove the protection cover from the terminal block connectors.

5. Connect the terminal block to the ASM-MN-214 terminal block

connector.

6. Connect the line to the terminal block as follows: connect transmit pair

to the terminals marked XMT, the receive pair to the terminals marked

RCV, and the fifth screw to ground (optional).

7. If required, attach the appropriate CIA (CIA/X.21 or CIA/V.35/1) or V.36

adapter cable to the DB-25 connector on the card cage rear panel.

8. Connect the DTE cable to the DB-25 connector, other side of CIA or

adapter cable (depending on your version of the card interface).

9. Connect power to the ASM-MN-214 card cage:

• To connect AC power, connect the power cable to the mains supply.

•

To connect DC power, refer to DC Power Supply Connection

Supplement.
