Hello.
On qfx5100-48s switch LED status and Chassis hardware status absent after upgrade JunOS starting from version 19.
For example, with version 18.1R3-S6.1 - LED Status is blinking and "show chassis hardware" show the "Xcvr 7 NON-JNPR MTC230307WR SFP-T". After upgarde to version 19 or 20 - LED light is off, and "show chassis hardware" show nothing, but interface work properly.
Is there a solution to the problem?
