10G ports are not seen in the 'show interfaces terse' output of an MX5-T device when the required license is expired.
'show interfaces terse'
A MX5-T router by default supports only one MIC slot with 20 port Gigabit Ethernet MIC enabled. Separately purchased upgrade licenses permits the use of a second MIC slot and four 10-Gigabit Ethernet (10GbE) interfaces. Refer the following technical document for more on licensing:
There are scenarios where the the license is not applied on the MX5-T (while upgrading existing device or while replacing the existing device with an RMA), then the device would run on the temporary license for a grace period. Once this grace period expires, the system would fail to create even the existing 10G ports, eventually making all 10G ports non-operational.
The following syslog message would appear in the chassid log, indicating an expired license:

Once the license expires, any 10G port on the device does not show up in 'show interface terse' . Any 1G port would still continue to function normally.

The PIC would still be shown online. However, the ports will be detached from them:

Check the output of ' show system license' . It would indicate that upgrade licenses are missing.

Check if the device was recently upgraded and a license was not installed on it or if the device was replaced with an RMA and the RMAed device was not installed with a license.
To transfer license keys to an RMA replacement device, refer to KB13500 - Transfer license keys to an RMA replacement device [juniper.net]
The output of 'show system license', once the required license is installed on MX5-T, would appear as below. It should have MX5 to MX80 upgrade licenses:
