Hi Zain, if you loop 2 ports and you don't see any led/link, there are couple things we can check, but you need CLI access (console access since no ports are up) or at least the last updated configuration file/backup.
The switch can have some features that will disable the port if a loop is detected (not enable by default, but someone could have enabled that). Also, as already mentioned before, CLI access will assure all ports are enabled and we will be able to provide a better guidance or even run a switch extended diagnostics.
