Line Weights: When reconfiguring LlCs, ensure that the total weight of lines
connected to a low-speed scanner is within the scanner maximum capacity. To
calculate them see Appendix A, "LSS Characteristics and Line Weights."
Step
1 Starting
If you have not done Steps 1 and 2 of the procedure "Getting Started"
on page 1-2, do so now.
Step 2
Locating the
Lie
slot
Use the LlU tables on the inner surface of the open unit door.
Following are schematic representations of the possible locations of
LlCs and their line numbers within the unit you have opened.
The following tables are for an LlU1 (LiC types 1, 3, and 4).

For example,
1m
is the number of port 0 for the
LIe
in slot H (in the upper half of the upper L1U 1
of the 3745 base frame unit).
Lie
3s have only one port but two types of
connectors: DeE (modem) or DTE (direct
attachment).
For LUI2 (LiC types 5 and 6), refer to the LICSI6 Migration and
Integration Guide, SA33-0416 or earlier version of the Connection and
Integration Guide, SA33-0129.
Repeat this step for every LlC to be inserted or removed.
If you are only installing a L1C, go to Step 4 on page 1-20.
If you are only plugging in a LIC cable, go to Step 8 on page 1-22.
Otherwise, continue with the next step.
Step 3
Deactivating line
Ask the host operator to deactivate all the lines connected to the LlC
you want to work with.
Attention - - - - - - - - - - - - - - - - - - - - - ,
Deactivation of all the lines of the L1C is necessary to prevent
problems at line adapter restart.
The line number is the same as the LlC port number.
For L1C types 1, 3, and 4:
There are up to four lines per LlC.
