I understood the default port for SSH is 9222 on TOS :

@Mac ~ % ssh -p 9222 [email protected]
** WARNING: connection is not using a post-quantum key exchange algorithm.
** This session may be vulnerable to "store now, decrypt later" attacks.
** The server may need to be upgraded. See https://openssh.com/pq.html

What is the default password ?

My F5221 board stopped working. I was told to by a F6424. The question is, what is required to move my F5 RAID drives to the F6 chassis.
Do I need to simply install the drives and power on?
Do I need to add a new drive and bring it up to speed and then add my 5 drives from my F5?

Please provide any links or knowledge on this process

You need to confirm your original TOS version. If it's a newer version like TOS6, you can boot directly from the installation hard drive. If it's an older version, you'll need to add a new disk to install the system. We recommend scheduling a remote migration with an engineer via the official website's online chat after your new device arrives.

The default boot system for the F6-424 is TOS 6. You can install TOS 6 on a new hard drive and then insert the five old hard drives to read the data. If the system on the old hard drives is functioning normally, you can also remove the internal USB drive with the bootable system and directly insert it into the old hard drive to boot the NAS.

Sorry to say the F4-220 is hardly a recent device. I think it was designed for the Tos4 era. Please see this regarding Tos4 EOL:
viewtopic.php?p=56215#p56215
and suggested Tos operating system version(s).
Further, the -220 series do not appear in the list of supported devices for Tos7 (see recent release notes).
F5-221 TOS7.0.1130 - 4x4TB (Ironwolf) Traid
F2-424 TOS7.0.1130 - 2x500GB nvme (P3) Traid, 2x6TB HDD (HGST) Traid
F2-221 TOS7.0.1130 - 1x3TB Ext4, 1x4TB Btrfs
F2-425+ TOS7.0.1130 - 2x500GB nvme (P3) Traid, 2x6TB HDD (EXOS) Traid
