LTM 7200v-ssl

Is there a document where i can find how the interfaces are numbered in the LTM 7200v-SSL? From the datasheet i can find it has 4 x 10/100/1000 Copper ports and 8 x 1G/10G fiber ports. From the images of front-panel i see the 4 x Copper ports are numbered as 1.1 to 1.4. And the 8 fiber ports seem to be numbered as 1.1 to 1.8. Is this the right numbering or the 8 fiber ports are numbered a 2.1 to 2.8 ???
