The SED is the expiration date for the support entitlements based on your Software Support (SSI), Software Support Plus Upgrades (SSU), Support Advantage (SA) or co-delivery support contract (for example, Joint Services Delivery (JSD) or Partner Support Services (PSS)). If you have not purchased Avaya support coverage, the SED in the license file reflects a 90-day warranty period that starts when the license entitlements are first activated.
