. When deployed, copy the `EXTERNAL_IP` of the LoadBalancer service.
For more information, see xref:kubernetes/quickstart-cluster/access-outside-k8s.adoc[Access the Neo4j cluster from outside Kubernetes].
. In a web browser, open the Neo4j Browser at _http://EXTERNAL_IP:7474/browser_ and log in using the password you have configured in your values YAML files.
. Run the `SHOW SERVERS` command to verify that the cluster is deployed and running.
. Run the `SHOW DATABASES` command to verify that the standalone server is of type `primary` and the GDS servers are of type `secondary`.
. Verify that the cluster is deployed and running:

The output shows that the secondary servers are in state `free` and host only the `system` database.

== Enable the secondary servers to support analytic queries

To support analytic queries on the secondary servers, you need to enable them and change the `neo4j` database topology to include them.

. In Neo4j Browser, enable the secondary servers to support analytic queries:
+
[source, cypher]
----
ENABLE SERVER "f1478d5d-1718-4430-a9b6-26fe9695ca30";
ENABLE SERVER "16cd6e9c-aa5a-4737-8ed5-e0df36ce52d3";
----
. Alter the database topology to include the secondary servers:
+
[source, cypher]
----
ALTER DATABASE neo4j SET TOPOLOGY 1 PRIMARY 2 SECONDARY;
----
. Check the status of the `neo4j` database to confirm the change:
+
[source, cypher]
----
SHOW DATABASE neo4j;
----
+
[queryresult]
