The blue LED on the base enclosure of a Dell EMC PowerStore T typically indicates that the hardware is operating normally. This kind of LED indicator is usually designed to provide a quick visual confirmation that all systems are functioning as expected without any issues.

To establish an SSH session for running svc commands, the connection is typically made to the appliance's IP address using the default SSH port 22. This configuration is standard for managing storage systems via SSH.

Port 22 is the standard port for SSH connections. SSH (Secure Shell) is a protocol used to securely connect to remote systems, and it traditionally operates on port 22. This is the correct port used when establishing an SSH connection from one system to another, including between Dell EMC PowerStore appliances.

To avoid management software conflicts after both appliance nodes have rebooted in service mode, the first step must be to return node A to normal mode. This allows one node to operate normally, reducing the likelihood of conflicts since only one node will handle management functions at this point.
