Figure 1-4. Removing a Net Module from the Connector

Lift the module bracket up and toward the front of the tray to release it

from the metal tabs that hold it in place (refer to F

igure 1-3).

Verifying the Net Module Jumper Settings

Before installing an MCE1 net module, be sure the jumpers match the

requirements of your ASN. F

igure 1-5 shows the jumper locations on the net

module. T

able 1-1 shows the jumper options.

Caution: You must lift the module straight up. If you rock the module back

and forth or side to side, you can bend the connector pins. Attempting to

reinstall a net module with bent connector pins can damage the power supply.

Note: Jumpers S2 and S3 are open for 120-ohm operation, and for 75-ohm

operation with no earth ground connection. But for 75-ohm operation with an

earth ground connection, jumpers S2 and S3 are closed (S2 indicates transmit

with coaxial shield, and S3 indicates receive with coaxial shield).
