4 v Install a temporary SSH key if a key is not installed and CLI access is required.
4 v Restart the services used by the system.
4 A number of tasks that are performed by the service assistant cause the node canister to restart. It is not
4 possible to maintain the service assistant connection to the node when it restarts. If the current node on
which the tasks are performed is also the node that the browser is connected to and you lose your
4
4 connection, reconnect and log in to the service assistant again after running the tasks.

Accessing the service assistant

The service assistant is a web application that helps troubleshoot and resolve problems on a node
canister.
To start the application, perform the following steps:
1. Start a supported web browser and point your web browser to the service address of the node that
you want to work on.
Each node has a different service address. If you are unable to connect to the service assistant, see
"Problem: Cannot connect to the service assistant" on page 38.
2. Log on to the service assistant using the superuser password.
If you are accessing a new node canister, the default password is passw0rd. If the node canister is a
member of a cluster or has been a member of a cluster, use the password for the cluster user
superuser.
If you do not know the current superuser password, reset the password. Go to "Procedure: Resetting
superuser password" on page 40.
3. Ensure that you perform the service assistant actions on the correct node. If you did not connect to
4
4 the node canister that you wanted to work on, access the Change Node panel from the home page to
4 select a different current node.
Commands are run on the current node. The current node might not be the node canister that you
4
connected to. The current node identification is shown on the left at the top of the service assistant
4
4 screen. The identification includes the enclosure serial number, the slot location, and if it has one, the
node name of the current node.
