Installing an ADSL or ADSL2+ LIM

ADSL LIM Hardware

1 - 8

363-217-018R9.8

Issue 1, August 2005

WARNING

...........................................................................................................................................................................

Keep the connector on the LIM being inserted away from
components on adjacent LIMs.

Do not force the card.

........................................................................................................................................................................................................................

2

Once the card has engaged its bus connector, press firmly to be sure it is fully seated.
Depress both ejectors simultaneously.

........................................................................................................................................................................................................................

3

If the LIM is equipped with an ejector lock, slide the ejector lock up.

........................................................................................................................................................................................................................

4

Using a number 2 Phillips screwdriver, secure the LIM by tightening the thumbscrews.

Verifying operational status

Once the LIM is installed. Allow three to five minutes for it to become operational. Then
observe the behavior of the status lights on the LIM to verify its operational status.
