Install the Discovery Console for OT on a virtual machine. Note: After installing the Console and the Operating System (OS) on a virtual machine (VM), the VM must have a minimum of 10-GB of unused space available. ## System requirements {#reqs-ot-console-installation__section_ust_3rx_vgc} The table lists the minimum resource requirements for the Discovery Console for OT. For more information, see [OT Discovery System Resources](https://www.servicenow.com/docs/7hCPeacyjpy8qc3EEjgocg "You can review the OT Discovery component resources before setting up your OT network.").{#reqs-ot-console-installation__table_i5f_kpx_vgc__entry__2} | Component | System Requirements | |-|-| | Discovery Console for OT | * 16 GB RAM * 100 GB Hard drive * 2 CPUs {#reqs-ot-console-installation__ul_c12_cqx_vgc} | [Table 1. System Requirements] {#reqs-ot-console-installation__table_i5f_kpx_vgc} Note: The required dependency version has been changed to .NET 10 from .NET 8 ## Network requirements {#reqs-ot-console-installation__section_l5d_p1z_4gc} The Discovery Console for OT requires the following ports to be open inbound (from the connection source to the Console) to operate. {#reqs-ot-console-installation__table_pxw_hym_33c__entry__2} | Ports | Description | |-|-| | TCP 5671 | Used by Discovery Sensor for OT to communicate with the Discovery Console for OT. This port is used by the Sensor to report data and receive configuration updates from the Console. | | TCP 8443 | Used to connect to the Discovery Console for OT Web interface. This port is used by the API. | | TCP 5002 | Enables Sensors to communicate with the Discovery Console for OT to receive updates. | | TCP 443 | Used for network communication from the Console to a ServiceNow instance or MID Server via the Service Graph Connector for OT Discovery. | | UDP 123 (Required) | Enables Sensor devices to synchronize time (real-time clock) with the Discovery Console for OT to verify that the time associated with reported data and events is both precise and accurate. **Note:**Without port UDP 123 open on the firewall, the clocks of Sensors drift apart from the clock of the Console. When clock drift is present, various features that rely on precise clock synchronization don't work as expected. | [Table 2. Network requirements] {#reqs-ot-console-installation__table_pxw_hym_33c} Note: If there are problems accessing the Discovery Console for OT, check the firewall rules and unblock the specific IP addresses and ports used for the installation.
