Protecting Your POS Systems

In last month’s newsletter, we talked about protecting your data.  In this past month, many of us lived through Hurricane Irene and then Tropical Storm Lee and many of us were greatly impacted by the devastation.  While the recovery has begun, it will take quite some time for many people and business to get back to some sort of normalcy.  In this article, we will revisit the simple yet important things that retailers could do to protect their POS system and minimize the time to recover in the event of devastation.

UPS
UPS (Uninterruptible Power Supply), especially the battery backup side of the UPS, is critical to keeping your POS system running smoothly.  During the storm season, the chance of power interruption increases in the form of blackout or brownout.  Blackout is easier to detect but brownout may not be easily felt.  Power fluctuation can also cause a power surge.  Any one of these power outage scenarios could damage your POS system or any electronic devices that are not protected by a surge protector or UPS.  If any of your POS system devices are not plugged into an UPS, you should consider purchasing one.  If you have UPS’s and do not remember when they was installed or replaced, you should replace them.  You don’t want to replace your car battery after it dies and you don’t want to wait until any part of your POS system sustains damage before you install or replace your UPS.

Backup
Your POS system is equipped with backup devices and media.  There may by automatic file backups but there is always a removable backup device and media in the form of external hard drive, DVD-RW drive and discs.  This should be your daily or weekly routine to make sure your system is backed up to the removable media.  This will allow for the quickest way to restore your system after a hard drive replacement.  Make sure making removable backup is part of your operational routine, just like counting cashiers and running reports.

Venting/Cooling
Take a moment to inspect the surroundings of your POS equipment.  All electronic equipment will have vents for cooling.  Take a look to make sure your POS equipment has room for cooling.  Look at the vents and make sure the vents clear of dusts and are not blocked.  Although your IBM POS systems are designed to withstand the toughest condition in the retail environment, it is still a good practice to help your system running at peak performance.

In the event of an imminent storm approaching, the logical thing to do is to move your mission critical equipment out of harm’s way.  If flooding is possible and moving all the equipment out of the store is not workable, one of the things you could do is to move the equipment to the top of the conveyer belt.  However, if flooded, cables, especially network cables, should be replaced.  Remember, the three most important things to do to ensure the least amount of down time is backup, backup and backup.
