Mounting the installation media and verifying the mount point

The IRIS/RDA installation media can be either a USB drive or a DVD disc.

Install the USB drive in the USB port of the server, or install the DVD disc in the DVD drive.
If you are using a DVD drive, a small black window indicates that the DVD disc has been recognized.

Select X in the upper right corner to close the window.
Verify that the installation media is recognized with the mount point by typing:
```
df
```
The installation media should be listed with the mount point in /run/media/root/irisrda_X.XX.X, where X.XX.X is the version of software you are installing.
If you do not see the installation media listed, try the following:
- Insert the USB drive to a different port
- Run the lsblk command to see if the installation media shows on the list. If it shows, mount it manually with the command:
```
 mount -o loop dev/<usbdevice> /mnt
```
  , where usbdevice is the name of the USB drive from the lsblk list.
  In the case of a DVD, replace <usbdevice> with the the DVD from the lsblk list.
