We have faced an issue on Juniper MX960 that some SFPs (10G Optics) were disabled due to ambient temperature exceeded. This was observed in the syslog messages on MX. However after the physical environment being ok , those SFPs were not coming up. Hence the corresponding 10G links were also down.
As per Juniper Documentation , the optics that have been disabled due to temperature can be reactivated through CLI. (https://www.juniper.net/documentation/en_US/junos/topics/reference/command-summary/request-chassis-optics.html)
request chassis optics fpc-slot fpc-slot-number reactivate
But the above command activate only NON-NEBS compliance optics. In our case optics are NEBS compliance verified by shell interface on MPC.
Can someone please guide how to activate NEBS compiance optics that has been disabled by ambient temperature exceeded.
