Question Been a fool and am Locked out with Plesk Firewall blocked IP for SSH and Admin

[Drimbrull]

Hello,

My server is running an up to date version of Obsidian. I locked all but my IP from SSH, FTP and Admin for a PCI scan to pass, but my router was restarted before I could revert meaning I now have a different IP address and cannot access through SSH or access the Admin panel on :8443

I can get the server put into recovery by my supplier (it is running CentOS6) but wanted to know what to do whilst in recovery to turn off the plesk firewall so I can have access to the admin panel when it then restarts.
