Quick Resource Locator
A useful feature included with Dell PowerEdge 12
(QRL) — a model-specific Quick Response (QR) code that is located inside the R520 chassis cover
(see Figure 6). Use your smartphone to access the Dell QRL app to learn more about the server.
This QRL code allows you to:

View step-by-step videos, including overviews of system internals and externals, as well as
detailed, concise, task-oriented videos and installation wizards

Locate reference materials, including searchable owner's manual content, LCD diagnostics and
an electrical overview

Look up your service tag so you can quickly gain access to your specific hardware configuration
info and warranty information

Contact Dell directly (by link) to get in touch with technical support and sales teams and provide
feedback to Dell
These codes provide an easy way to retrieve the critical support information you need when you
need it, making you more efficient and effective in managing your hardware.
