# Installing version 2.0.0 for PDM II

## Scope

This document applies only to the PDM II. it can not be installed on original PDM units with versions 2.4.x or 2.5.x

## Release notes for PDM II versions

Please [refer to this document](/v1/docs/pdm-ii-release-notes#version-200) to see release notes for this (and other) versions[.](/v1/docs/pdm-ii-release-notes) (will open in a new tab)

## Installing the update

### Do I need to physically bypass my unit before updating?

It depends on your I/O Configuration. Activation of any new software requires a reboot.

All PDMs contain a BYPASS relay, which will cover some cases; however, the BYPASS relay can only bypass the same PHYSICAL sources (Analog in to Analog out, etc.) and does not bypass any AoIP sources. [Please refer to this document](/v1/docs/pdm-ii-bypass-functionality-defined) for more information on how BYPASS works in the PDM II.

> [!CAUTION]
> Plan accordingly.

### Getting the file and updating the firmware

1. [Click here to download the update](https://telos-support.s3.us-east-1.amazonaws.com/25-Seven/PDMII/1601-00586-004-pdmii-2.0.0.epkg). Save this file on your computer for use in the next steps.
2. In a Web Browser, navigate and log in to your PDM II.
3. Click the **UTILITIES** link from the main menu across the top.
4. Click the **Choose File** button. Then browse for and locate the update file you downloaded in step 1.
5. Click the **Install package** button. The installer package will be uploaded to the unused bank. In this example, note that Bank 1 is the running bank, so the button says "Install package on Bank 0". THIS STEP WILL **NOT** CAUSE A PDM REBOOT and is safe to complete while the PDM II is in use.
