When it comes to load-shedding each site will have one of two scenarios:
Scenario one: The Store has a UPS
In the case where the Store has a UPS (Uninterrupted Power Supply, or battery backup device) installed, once load-shedding starts the UPS will start to beep. Once it starts beeping you will have about 2 - 5 minutes to correctly shut down the computers before the UPS goes flat.
Very important:
The UPS is not meant to run the store when the power goes off. It only serves to allow time to shut off your devices safely.
Do not leave the UPS to go flat and the computers turn off by themselves - this can corrupt the hard drives and cause you to lose data.
Print out all the necessary slips or reports and shut down the computers before the UPS goes flat.
Below is an example (Note that not all the models look the same but they have mostly the same design)
Steps on shutting down the server and tills:
Please note that all Windows computers have the same shutdown process:
Step 1: Close all the open programs on each computer by clicking on the "X" in the top right corner of each program.
Step 2: In the bottom left corner of the screen select the "Start" / "Windows" key.
Step 3: Select the "Power" / "Shut Down" key. (Depending on the version of windows).
Step 4: This step only applies to certain versions but the computer will ask you to confirm shut down, please select confirm.
Once you have confirmed the computers will shut down, this process needs to be completed on each computer.
Scenario two: "The Store does not have a UPS"
In the case where the Store does not have a UPS installed, once load-shedding starts the computers will all instantly switch off.
