workarounds: Lenovo has ended support for legacy IBM System x 3550 M3 and IBM System x 3650 M3 servers as of December 31, 2019, therefore Lenovo recommends discontinuation of use.  If it is not feasible to discontinue use of these systems, Lenovo recommends customers:
Disable SSH and Telnet (This can be done in the Security and Network Protocol sections of the navigation pane after logging into the IMM web interface)
Change the default Administrator password during initial configuration
Enforce strong passwords
Only grant access to trusted administrators
