Every now and then we happen to a see strange case with our linecards
(MPC 3D 16x 10GE). After a linecard reboot one of the optics sometimes
stops sending light:
Physical interface: xe-2/3/3
Laser bias current : 0.000 mA
Laser output power : 0.0000 mW / - Inf dBm
Module temperature : 22 degrees C / 71 degrees F
Module voltage : 3.2220 V
Receiver signal average optical power : 0.2459 mW / -6.09 dBm
Reseating interface help, but in remote locations it is not really
handy. Disabling/enabling interface doesn't help.
Any tips of how to deal with it without asking remote hands support?
I will greatly appreciate anything that helps.
