Hello Ronald,
It is unclear if this is an AP7522E express unit or a standard AP7522 with the Express (Swift) UI. If it's an Express unit meaning AP7522E, then as previously mentioned, it has to be factory reset via the console port; however, if it's a standard AP7522 unit with Express UI, then you can console into it (baud rate 115200) and run the following commands to open the GE1 port:
>en
#self
Enter configuration commands, one per line. End with CNTL/Z.
#int ge 1
#no shut
#com wr
Regards,
Chris
