+# Installing Photon OS on Dell Edge Gateway 300X

+

+You can install Photon OS 3.0 on Dell Gateway 300X. You can download Photon OS as an ISO file and install it.

+

+- [Prerequisites](#prerequisites)

+- [Installing the ISO Image for Photon OS](#installing-the-iso-image-for-photon-os)

+

+## Prerequisites

+

+1.	Verify that you have the following resources:

+    - Dell Edge Gateway 300x.

+    - USB pen drive. Format the pen drive with FAT32 with at least 8 GB of space.

+2.	Download the Photon OS ISO image from [Bintray](https://bintray.com/vmware/photon/).

+

+## Installing the ISO Image for Photon OS

+

+1.	Mount the ISO image.

+    

+    For example, run the following command on macOS:

+

+    `hdiutil mount photon-3.0-ec12f2c.iso` 

+

+    Use a similar command in other operating systems.

+

+1. Copy the contents of the ISO image to a writable directory so that you can edit files.

+    For example, run the following commands on macOS.

+        

+    ```

+mkdir -p /tmp/photonUsb

+    

+    cp /Volumes/PHOTON_<timestamp>/* /tmp/photonUsb/

+    ```

+

+    where, `/Volumes/PHOTON_<timestamp>` is the directory where the ISO is mounted with the command in the step above.

+

+1. Edit the `grub.cfg` file to use the kickstart config file:

+    

+    `cd /tmp/photonUsb`

+

+    Add the below (highlighted) parameters to the linux cmd line in `boot/grub2/grub.cfg`

+    

+    `linux /isolinux/vmlinuz root=/dev/ram0 loglevel=3 photon.media=UUID=$photondisk` **`ks=cdrom:/isolinux/sample_ks.cfg console=ttyS0,115200n8`**

+

+1. Edit the `isolinux/sample_ks.cfg`  as follows:

+

+    - Change `"disk": "/dev/sda”,` to **`"disk": "/dev/mmcblk0",`**

+    - Change `"echo \"Hello World\" > /etc/postinstall"` to **`"sed -i 's/PermitRootLogin no/PermitRootLogin yes/g' /etc/ssh/sshd_config"`**

+    

+1. Format the pen drive with FAT-32 and copy all the contents of `/tmp/photonUsb` to the pen drive. 

+

+1. Create a `UsbInvocationScript.txt` file in the root of the pen drive with below content:

+

+    ```

+usb_disable_secure_boot noreset;

+usb_one_time_boot usb nolog;

+```

+

+1. Insert the pen drive in the Dell Gateway 300X and power on the gateway. 

+    

+    Photon OS installs automatically.

+

+1. After the installation is complete, insert a network cable into the ethernet port and find the IP address corresponding to the MAC address of the Dell Gateway 3000X ethernet port through the DHCP Server or a network analyzer. The MAC address is available on the Dell Gateway 3000X.

+

+1. You can then use `ssh` to access the gateway with the above IP address.
