3. Once inside go to the orange job selector circle and select Server Repair.
4. Go to the green circle beside the job selector and buy your server repair supplies. You need these to complete repair jobs and if you plan on doing this job for a while you should purchase a lot. You can also come back to this location and purchase more if you run out.
5. Wait for a call out to appear in the top right area of your screen. The callout details the supplies you will need, as seen in the image below.
6. Go to the location marked on your map as Job (Server Repair) and repair the server. All the server repairs are inside this interior.
7. You will keep receiving callouts until you switch jobs.
