Is this switch part of a cluster of other VDX switches, does the switch show as part of the VCS logical-chassis from show vcs command when run on another node in the fabric?
When enabling logical-chassis mode on a VDX the configuration will be set to default and the switch will be rebooted with default configuration

It was the first switch that I tryed to convert in order to form the logical cluster.
there is a way to have access for management enstead the external console port? the console port cable is a miniUSB-RS232 and not shipped with the Flex Chassis IO Module.

When the switch is converted it should maintain it's management IP address even though it is defaultted and as such should still be reachable. Do you have only VDX 2740 in your fabric or other VDX devices.
The part numbers I have for the mini-USB cable is either 50-1000122-01 or 50-1000059-01 one of these is an ICX cable but this is also compatable.

What hapended is that all the switch became protected please see in attachement a printscreen from the Chassis management.
I have a second one on IO1 but I am afraid to do the same think an lost all connectivity operation for the servers, when I try to connect the two switch I have "[FABR-1001], 5186, SW/0 | Active, WARNING, EN4023, Interface TenGigabitEthernet 1/0/45, ESC Config Mode conflict." and this is normal because the IO1 switch are still fabric Cluster and the IO2 on Logical Cluster.
I have opened a case with IBM/LENOVO and will provide a new one, but I am still waiting a feedback regarding the FoD that are enabled on the unreachable one, I don't know how to tranfer them to the new one bacause the two FoD was factory enabked before the shipping of the material, I am waiting the new one in order to see if the FoD are integrated or I have to open a new case for that !!

I am not sure why the switch you have configured as logical chassis has gone into protected and is no longer reachable, as this is the only switch in logical chassis mode I would expect that it should be principal switch in LC and as such would be available to manage.
As you mention the 'Config Mode conflict' would be expected with one switch on LC mode and the other in FC mode.
I think that you may need to work with Lenovo support to rectify this problem

When I have logued a case regarding the protectedt mode the IBM support team conclude that the switch have to be changed, from other side when I took a look on the readm file of the NOS6.0.2a that is the last firmware upgarde for the switch I found on the known issue :
- VCS Logical Chassis mode has been disabled in this release,
And this is not documented on the Brocade NOS admin guide nor the Lenovo documenntation (tips)
The VDX2740 is the EN4023 Switch: 10Gb scalable switch for IBM Flex System Fabric based on the VDX 6740 ToR switch.
