this network identity, you must reconfigure the entire system from the start. Contact your Grass

Modifying K2 Media Server FTP network settings
You can modify the FTP network settings using SiteConfig without directly affecting the media file
system or metadata service. However, you must be aware of the requirements of your site’s FTP,
file transfer, and streaming system design, as the FTP network settings will likely need to be changed
elsewhere.
After modifying FTP network settings using SiteConfig, open the Network Configuration page in
the K2Config application. The settings should automatically update. Verify that the settings are
correct.
Modifying K2 Media Server media network settings
Use this procedure if you must change the IP address assigned to an iSCSI interface board on a K2
Media Server. This should not be necessary for a normally operating system and in fact it should
be avoided if possible.
1. Put all the devices of the K2 SAN in an offline or out of service state. Refer to the appropriate
procedures in this chapter.
2. Open the K2 System Configuration (K2Config) application on the control point PC.
3. In K2Config, make sure you know the load balancing bandwidth parameters for each of the
iSCSI clients, as you must re-enter these values later in this procedure.
4. In K2Config, remove all iSCSI clients from the K2 SAN. To do this, select each iSCSI client
and click Remove.
5. Use SiteConfig to change the IP address. Make sure that the IP address is within the range
designated for the network.
6. Restart the K2 Media Server.
7. In the K2Config tree view, expand the node for the media server that has the iSCSI interface
adapter for which you need to change the IP address and click the iSCSI Bridge node. The iSCSI
Bridge Server configuration page opens.
8. In K2Config, identify the iSCSI adapter for which you are changing the IP address. Since you
changed it in SiteConfig, K2Config should now display the new IP address.
9. In K2Config, add each iSCSI client again and reconfigure. Make sure you add them in the correct
order (highest bandwidth first) and enter the same bandwidth values (load balancing) for each
client as the values originally configured.
10. Place the devices of the K2 SAN back online.
Configuring Server 2008 for domain
This topic applies to Grass Valley servers with a base disk image created prior to mid-2011. Server
disk images created after that time do not require this special configuration.
Systems with the Microsoft Windows Server 2008 operating system require special configuration
when on a domain. A server must have its firewall disabled for proper K2 system operation. This
includes the Windows firewall that is only in effect for systems on a domain. On Microsoft Windows
Server 2008 servers, the domain firewall setting does not appear in any configuration dialog box
