This guide describes the process for building a new Remote Management
Unit (RMU) that converts a Gen-1 site into a Gen-1.5 site. It mirrors
how DFINITY monitors its own ICR sites using equipment that is already
standard in most Gen-1.a installations.

This page is the table of contents. The detailed procedures live in
the linked sub-runbooks below — start with
[Prerequisites](/wiki/rmu-build-prerequisites/) and work through each
section in order. Completing everything up through
**V. Best Practices** gives you remote access to the RMU and the
ability to add additional services via Teleport. The Best Practices
section adds services that significantly improve the operator
experience, such as updating firmware on every server remotely.

> [!WARNING]
> This guide provides only the foundational steps for setting up a
> Gen-1.5 RMU. It does not encompass comprehensive security hardening,
> nor does it address ongoing system maintenance. Responsibility for a
> secure and well-maintained environment rests with each node provider.

## I. Prerequisites

Cover the prerequisites before any of the build steps below — see
[RMU Build: Prerequisites](/wiki/rmu-build-prerequisites/).

## II. Proxmox

Once Proxmox is installed and reachable (step II.A), the rest can be
done remotely. See [RMU Build: Proxmox Setup](/wiki/rmu-build-proxmox/).

1. **[A. Install Proxmox](/wiki/rmu-build-proxmox/#a-install-proxmox)**
2. **[B. Update Proxmox](/wiki/rmu-build-proxmox/#b-update-proxmox)**
3. **[C. Download CT templates](/wiki/rmu-build-proxmox/#c-download-ct-templates)**
4. **[D. Download ISO images](/wiki/rmu-build-proxmox/#d-download-iso-images)**
5. **[E. Add LAN network device](/wiki/rmu-build-proxmox/#e-add-lan-network-device)**

## III. Teleport

This service provides secure remote access to all of the services
installed on your RMU. See
[RMU Build: Teleport Setup](/wiki/rmu-build-teleport/).

1. **[A. Create Teleport CT](/wiki/rmu-build-teleport/#a-create-teleport-ct)**
2. **[B. Install Teleport software](/wiki/rmu-build-teleport/#b-install-teleport-software)**
3. **[C. Share RMU services via Teleport](/wiki/rmu-build-teleport/#c-share-rmu-services-via-teleport)**
4. **[D. Teleport notes](/wiki/rmu-build-teleport/#d-teleport-notes)**

## IV. MaaS (Metal as a Service)

See [RMU Build: MaaS Setup](/wiki/rmu-build-maas/).

1. **[A. Create Proxmox CT](/wiki/rmu-build-maas/#a-create-proxmox-ct)**
2. **[B. Install MaaS software via APT](/wiki/rmu-build-maas/#b-install-maas-software-via-apt)**
3. **[C. Share services via Teleport](/wiki/rmu-build-maas/#c-share-services-via-teleport)**
4. **[D. Initial configuration of MaaS server](/wiki/rmu-build-maas/#d-initial-configuration-of-maas-server)**
5. **[E. Configure DHCP subnet on MaaS](/wiki/rmu-build-maas/#e-configure-dhcp-subnet-on-maas)**

## V. Best Practices

See [RMU Build: Best Practices and Reference](/wiki/rmu-build-best-practices/).

1. **Recommended — [A. Proxmox security](/wiki/rmu-build-best-practices/#a-proxmox-security-recommended)**
2. **Optional — [B. Install RACADM tool on RMU (Dell nodes)](/wiki/rmu-build-best-practices/#b-install-racadm-tool-on-rmu-optional-dell-nodes)**
3. **Recommended — [C. Dell OpenManage Enterprise (OME) (Dell nodes)](/wiki/rmu-build-best-practices/#c-dell-openmanage-enterprise-recommended-dell-nodes)**
4. **Recommended — [D. Update firmware on SuperMicro nodes](/wiki/rmu-build-best-practices/#d-update-firmware-on-supermicro-nodes-recommended)**
5. **Recommended — [E. Enable remote access to server console (Dell nodes)](/wiki/rmu-build-best-practices/#e-enable-remote-access-to-server-console-recommended-dell-nodes)**
6. **Recommended — [F. Enable GUI access to OPNsense devices](/wiki/rmu-build-best-practices/#f-enable-gui-access-to-opnsense-devices-recommended)**
