Caution — When sliding the LT card into slot 9, ensure that the solder

screws located at the top and the bottom of the front panel of the card; see Figure 61.

In the same way, install all the planned LT cards for the shelf.
Install LT card dummy panels in any unused, unpopulated LT card slots to maintain proper
