Maintain an Infoblox VM-1550 Base deployment under an initial 1-year Premium Maintenance term. IB-MAIN-VM-1550-BASE-Y1-3-01 identifies the premium maintenance selection designated for the Years 1 to 3 period, linking the service term to the VM-1550 Base platform. This service applies to the base virtual appliance designation rather than representing a physical appliance, add-on module, or standalone software entitlement. The ordering code includes the VM-1550 and Base references, helping distinguish the supported platform from maintenance options intended for other appliance capacities or product configurations. Premium Maintenance is the named service tier for this term. The initial designation differentiates this service selection by its starting coverage period, while the 1-year designation establishes the service duration. Use it where a VM-1550 Base environment requires the Premium Maintenance tier for the stated Years 1 to 3 maintenance stage.
