Maintain an installed Infoblox 250-A appliance under a 2-year Level 3 extended maintenance term. IB-EXTM-250-A-NS1-32 is a service entitlement associated with the 250-A platform, intended for environments retaining that appliance in production after its initial coverage period. It supplies an extended-maintenance term rather than a physical appliance, network interface, license capacity addition, or replacement hardware configuration. The Level 3 designation identifies the maintenance tier supplied with this term. Select this service where the deployment specifically requires extended maintenance coverage for the Infoblox 250-A and the desired coverage period is 2 years. Its appliance-specific scope matters in DNS, DHCP, IP address management, and network-services environments where the installed platform must remain aligned with its applicable maintenance entitlement. This item is differentiated by three ordering characteristics: it is tied to the Infoblox 250-A, provides Level 3 extended maintenance, and covers a 2-year period. It is not a general consulting engagement or an open-ended support allocation. Use the exact ordering code when the existing appliance is a 250-A and the requirement is to extend its Level 3 maintenance term.
