Note

This separate procedure is not needed if you install and update the firmware as part of a Sun Ray Software installation.

This procedure shows how to download and install the latest Sun Ray Operating Software (firmware) on a Sun Ray server and update the server's .parms files with the new firmware. Once the firmware server is updated, the Sun Ray Clients using that firmware server will download and update the new firmware on their next reboot.

This procedure is provided for Sun Ray servers that have been configured on a shared network (LAN) with external DHCP server support. For alternate network configuration, see the examples after the procedure.

If you need to enable the Configuration GUI on Sun Ray Clients once their firmware is updated, see Section 14.4, “How to Enable and Disable the Configuration GUI on All Sun Ray Clients”.

Download and unzip the latest Sun Ray Operating Software and make it accessible to the Sun Ray server.
See http://www.oracle.com/technetwork/server-storage/sunrayproducts/downloads/index.html
Become superuser on the Sun Ray server.
Change directory to the unzipped firmware directory and install the firmware.
```
# ./utfwinstall
```
Make the firmware accessible to the Sun Ray Clients:
```
# utfwadm -AaV
```
This command is for a Sun Ray server configured on a shared network (LAN) with external DHCP server support (used utadm -L on for network configuration). See the examples following this procedure for alternate network configurations.
Power-cycle the Sun Ray Clients to update to the new firmware.
Note
You can also use the utfwload -l command to force all Sun Ray Clients to update to the new firmware if they have older firmware and they are connected to the Sun Ray server .
Repeat this procedure on each Sun Ray server in a failover group being used as a firmware server.

Note

To update firmware versions for a specific client, use the -e enetAddr option, where enetAddr is the MAC address of the client.

Alternate Network Configuration Examples

Use the following utfwadm command examples for alternate network configurations:

On a shared network (LAN) with Sun Ray server DHCP support (used utadm -A subnet for network configuration)
```
# utfwadm -Aa -N all
```
On a private network (used utadm -a intf for network configuration):
```
# utfwadm -Aa -n all
```
