Dell PowerConnect MIB's

Dell PowerConnect MIB's

We want to monitor our network better than we do at the moment. To achive that, I want to create new Device Template and upload the devices corresponding MIB tables. However, I don't know how to handle the MIB files of Dell. I attached the ZIP file which containts the MIB files. The ZIP file containts multiple MIB files. I was expecting to receive only one MIB file and link this file to a new template. I don't know how to connect the right mib files to the right template. How should I read these mib files and link them to a new template?
 
I know I have to copy the mibfiles to ManageEngine\OpManager\mibs so that's not the point...
