Hardware Life Expectancy:
As to the original topic of this thread, here is a candid discussion about POS hardware. It is a bit long winded, but hopefully will clear up some questions. As a POS software development company who provides hardware to drive the software, we often hear the question of “How long should the hardware last?” Although I wish it were, the answer is not that simple.
If we were to take a POS computer, place it in a climate controlled medical office, use very expensive electrical filtering, and be used by respectful and sedate employees, these things would last a very long time. Since I haven’t had the luxury to test this elusive perfect computer environment, I can only guess how long the computers would last. What I can say for absolute certain is the restaurant environment looks nothing like what I just described.
Background: The majority of POS computer hardware comes out of a handful of overseas manufacturers, meaning we all pretty much have access to procure and use the same general equipment. The choice for the equipment any POS company provides comes down to relationships, track record, experience, investment and performance. Modern POS systems are very graphical and require a more powerful machine, while older and less involved text based systems can use virtually anything. The older systems are very good at the basic POS functions like taking and order, sending it to the kitchen, and checking the drawer. The newer systems using recent development platforms go much further in the features and nuances of those features.
Hardware Killers: Heat, Power, Abuse
Heat is not good for anything electronic and comes in three forms. The first is the temperature of the surrounding environment may force the computer hardware to run hotter. In the restaurant environment, computers in the office will last longer than ones in the kitchen. I have seen guys place their order entry station next to their oven because it was convenient for them, and they experienced faster failures.
The second cause of heat failures is not letting the computers breathe. For instance, when people use a separate computer and touch screen, the computer may be relegated to under the counter where it quickly gets pushed against the wall and covered with papers, towels, and other things that prevent it from cooling. The case slots are there for cooling. Let it breathe.
The third cause of heat failures is the restaurant environment of grease, flour, and other things in the air penetrating the computer through the case slots and covering the internal components. This gunk is an exceptionally good insulator and once again, the computer cannot keep itself cool.
Electrical Power – the hidden killer. Things like blackouts, brown outs, local construction, and storms are obviously highly detrimental to computer life expectancy. Other less obvious issues are substandard wiring, overloading a circuit, and power spikes. If you look around your location, there are a number of things that will send spikes through the entire electrical system every time they turn on, like refrigeration, slicers, etc. Anything with a motor or compressor will spike. If in the same outlet as a computer, it will cause havoc.
Storms and blackouts that immediately kill the computers are easy to detect, but the bigger issue is these and the other events can weaken the components causing latent future failures. A failure on a bright sunny day may actually have been started a few weeks earlier when a storm rolled though.
Abuse: There is nobody who cares about their investment like the owner, and many places have 16-18 year old disrespectful kids using the system. It’s not too far of a stretch to envision abuse. Other instances may be people dropping water and cokes on the equipment, or using sharp objects like pens to poke the touch screens.
What this Means: The restaurant environment can be a harsh industrial atmosphere, and computer life is affected by a number of things outside of the “quality” of the hardware. I will go out on a limb here and say there are no POS companies who plan on being around for awhile intentionally use junk equipment. The fact is, on a Friday night at 7PM an owner doesn’t want to make that excited call any more than we want to get it.
From my experience after a number of years in this business, POS hardware in the restaurant environment will last 5-6 years on average before they start seeing the bigger issues. The time is longer if in a safer environment, and less if in a more demanding harsh environment. If you have a POS guy who claims much longer, take it with a grain of salt.
Protection Ideas:
- If power is an issue or a concern, if you are in a hurricane or tornado zone, if you see blackouts or brown outs (lights flickering), you should protect yourself. Drop by Office Max or Best Buy and pick up a UPS for the server and router as a minimum. The model I particularly like is the APC 1000VA Power Saving Green Back-UPS XS - with LCD Display. They go for $139, but you can catch them on sale.
- Clean the equipment. Some customers blow out their computers with compressed air or a compressor. Heads up… if you are blowing off a fan, stick in a pen to keep it from spinning. If they over spin, you will ruin the bearings. If you take the machine outside, carefully mark where the wires plugged into.
- Keep water, cokes, and all liquids away from all hardware
- Do not put printers on a moving conveyor belt when cleaning make table. I saw that once.
- Do not drop printers in fryers. Seen it and not pretty.
- Do not put printers on floor and power wash floor, especially if still turned on. Same guy who put printer on belt.
- Do not saran wrap a computer to keep the dust out. Nice idea on the surface.
General Troubleshooting - check all wiring first
-
Code:
Power Supply Blown - electrical spike
-
Code:
Power Supply + Motherboard Blown - big electrical spike
-
Code:
Hard Drive Failure - it happens to even the best, like Western Digital
-
Code:
Router Blown or confused - electrical spike. look to replace
-
Code:
Touch Screen not responding - clean gunk on screen and around edges
Thanks for listening.
