1-22 Maintenance overview
SWLD command The SWLD command is a new command available at the
LCM level of the MAP display menu in position 13 and is applicable only to
RLCM-EDC nodes. When this command option is used on an InSv node, it
places the RLCM-EDC in a simplex mode for a short period of time. A
warning is displayed at the MAP terminal and operating company personnel
are prompted to confirm the command with an option to reject the
commands execution if desired.
When used on an InSv node with option UNIT, as shown in the following
example of a MAP display. The SWLD command places the LCM in the
takeover mode and the specified unit in an OOS mode and internally
switches the ACT and STBY flash ROM banks. It brings the unit back to an
InSv state, executing the new load in the newly active (previously STBY)
bank. When used with option PM on an InSv node, the command repeats
the sequence for both units in succession.

LCM REM1 01 0 Unit 0 SWLD passed.
The SWLD command when issued with a UNIT option first checks to see if
the mate unit is in service. The command is rejected if executed on an InSv
unit which has a OOS mate unit, as seen in the example below. To execute
the SWLD command on an InSv unit of a simplex node, use the RTS
command on the OOS unit. After successful completion of the RTS
command, operating company personnel can use the SWLD command with
the unit option.
>SWLD UNIT 1

The SWLD command will remove a unit from service creating
non-duplex operation. This command should be executed during
periods of low traffic.
