MAP 6010: How to run 3746-900 Diagnostic in Offline Mode
Ask the customer to stop all the traffic on the 3746-900. If APPN/IP is installed, deactivate the ports
concerned (refer to “Activate/Deactivate a Resource Via CCM” on page 1-150), then continue the proce-
dure from here.
When the 3746-900 is set in Offline Mode, it is faster to start all the diagnostics than to start a selected
diagnostic on a specific resource. Nevertheless, do not forget that when the 3746-900 has a CLP with an
LIC11 attached test duration time can increase up to one hour according to the number of ARCs installed.
001
Have you more than one CLP installed on the 3746-900?
Yes No
002
Go to Step 004.
003
Before starting this procedure see if CLP(s) are set in standard or backup mode in order to know what will
be tested during the Offline procedure. Go to “MAP: 3746-900 CLP Backup or Standard Mode Setting”
on page 1-146 to check the CLP status and change it if necessary. Then return here to continue with Step
004.

ready LED is ON. In case of a problem during IML, a code is displayed on the control panel. This
code can be flashing or steady (more than 60 seconds) while the ready LED is blinking.
Does the ready LED come ON?
Yes No
