6. Insert the new module. Make sure it is in the cardguides; push it
firmly into the chassis until it seats into the card-edge
connectors on the backplane. (Do not slam the board against the
backplane or push any harder than necessary to seat the
connectors.)
7. If desired, power up the station while it is still out of the case to
make sure the module is securely in place. The LEDs on the
Wireline should blink rapidly, indicating that firmware is
transferring from the SCM to the Wireline Module. When the
blinking stops, the transfer is complete.
If any of the LEDs do not light or are dim, one or more of the
modules are not seated properly. Unplug the station before
continuing to the next step.
8. Reassemble the station by reversing Steps 2 and 3.
Perform the following alignment procedures as described in the RSS
User's Guide (part number 68P81085E35):
• Rx Wireline
• Tx Wireline
1. Remove the Wireline Module as described above.
2. Unplug the faulty ASTRO Modem Card or the V.24 Interface
Card from the Wireline board by pressing the mounting posts
through the back of the board.
Install the replacement card by pressing it onto the Wireline board
and locking all mounting posts and connectors.
3. Re-install the Wireline Module as described above.
No alignments or adjustments are required. The card is configured
by the Station Control Module on power-up.
1. Turn off the station's power by unplugging the AC and DC
power cords from the top panel.
