To configure advanced settings

1. Under VoIP Call Managers, enter the IP address or FQDN of your VoIP Call Manager in the Call Manager 1 field. You can add two additional VoIP Call Manager addresses.

2. Under Network Boot Settings, in the Next Server field, enter the IP address of the PXE boot server (TFTP server) that a PXE client uses during the next stage of the boot process.

   The fields under Network Boot Settings are used in a Pre-boot Execution Environment (PXE), in which the client boots up using files obtained over a network interface. The PXE client obtains the IP address and name of the PXE boot server, and the boot file name, from the DHCP server.

   When using these options, select PXE under DHCP Generic Options.

3. In the Boot File field, enter the name of the boot file that the PXE client can get over TFTP from the PXE boot server.
4. In the Server Name field, enter the DNS host name of the PXE boot server (TFTP server).
5. For information on configuring DHCP Generic Options see Configuring DHCP Generic Options for DHCP Lease Scopes.
6. Click OK.
7. Click Accept for the settings to take effect on the firewall.
