Quick Resource Locator (QRL)

The Embedded Service Tag (EST) this generation will contain the Service Tag number and the iDRAC password. Embedding the Service
Tag and iDRAC password in the QRL allows the mobile application to display information on their configuration, warranty status, specific
iDRAC password and service level agreement. Additionally, the EST will allow us to understand how our customers are using QRL.
