FlexWash LAN

At a high level the FlexWash LAN looks like this. High Level Network(3) Pn

​
IP Assignment

Our FlexWash subnet is 172.16.184.0/24. Static Range: 172.16.184.1–172.16.184.199 (reserve .1 for the gateway; .0 is the network address, .255 is broadcast, don’t use either). All the devices we know of are programmed in this range. Dynamic Range: 172.16.184.200–172.16.184.254. Devices in this range are assigned by DHCP, which typically means that we don’t recognize them. Devices that we send commands to need to be in the static range, for example the tunnel controller. Devices that only issue commands can be in this range, for example pay tablets.

Edge Switch

Edswcln Pn This small switch is used to reduce the number of cables running to the checkout area from the main switch The Edge Switch is located in the checkout area. You’ll run a single Ethernet cable from the main switch (the large one in the network cabinet) to the Edge Switch. From the Edge Switch, you can connect other peripherals such as:
  • Camera
  • RFID Reader
  • Access Point
  • Gate Controller
    Edge Switch Port 1 must be connected back to the main switch.On the main switch, this cable must be plugged into Port 17 or above.

Battery Backup & Surge Protection

Car Washes use heavy electrical equipment and 3 phase power supplies. This increases the risk of power surges. Just one electrical spike can damage your essential equipment. It is very important to make sure you use the provided UPC correctly. Make sure ONLY FLEXWASH EQUIPMENT is plugged into this power supply. If you overload this power supply it will NOT work correctly.
Make sure the battery terminals are connected before you plug in FlexWash equipment. Image(7) Pn All FlexWash equipment must be plugged into the ports labeled Battery + Surge as shown on the image below: UPC Pn After a power surge, make sure you reset the internal breaker by pressing the button shown below: Breaker2222 Jp
The battery backup is only for transient protection but should give you around 30 minutes of failover during a power outage.
