# How to connect to the Java SOL on DRAGEN v3 Hardware

### **Background**

In some circumstances it may be necessary to access the operating system of DRAGEN v3 server via the Baseboard Management Controller (BMC). Assuming the BMC is accessible by network this procedure may be used for out-of-band management when the primary network is down or the host OS cannot be reached by SSH as usual.

### **Prerequisites**

Install a modern, open source implementation of Java Web Start such as [OpenWebStart](https://openwebstart.com/). The conventional Java Web Start (JWS) tool, from Java, is deprecated and will not load the Java SOL correctly.

### Connect to BMC

1. As detailed in the [DRAGEN v3 site prep guide](https://support.illumina.com/content/dam/illumina-support/documents/documentation/software_documentation/dragen-bio-it/1000000097923_03_DRAGEN-server-v3-site-prep-and-installation-guide.pdf), on page 18, the BMC should be configured with a static IP address using the command below:\
   `ipmitool lan set 1 ipaddr {IP address}`
2. Load the BMC WebUI by visiting http\://{IP address}(replacing {IP address} with the IP address set in Step 1).
3. Enter the configured username/password and select **Login**.
4. Navigate to **Remote Control** > **Java SOL** and select the **Java SOL** button to download the .jnlp launcher.
5. Fill the IP, username, password details and select the highest Volatile and Non-Volatile Bit Rate options (115.2K) and select **Connect**.\
