Wi-Fi Configuration

This article includes the following:

Example 1: Restricted LAN Access

Example 2: Using „Wi-Fi Only“:

For this option, Firmware 2.24 or above is required
For this option a CS141 / BACS must provide hardware revision HW161 and a USB port

With the WLAN option, the CS141 offers a flexible extension for integration into network systems. The use of the new USB-WLAN option depends heavily on the application scenario. 

First, typical possible applications are discussed.

Example 1: Restricted LAN Access

Due to ever-increasing cybersecurity requirements, more and more end users are closing their networks. This means immense additional work on site for technicians from service companies. Via the WiFi dongle, the CS141 or BACS now offers an independent network interface through which a technician can connect directly if necessary.
The special feature is once configured, a CS141 remembers the Wi-Fi settings even if the USB dongle has been removed. This means technicians can set up an SSID for a mobile hotspot during setup, and insert the USB dongle at any time later - the CS141 will automatically connect to the mobile hotspot.

Example 2: Using „Wi-Fi Only“:

WLAN Only takes two theoretical approaches to how valuable UPS data can be queried directly without compromising network security.
In the first approach, the UPS is connected to a CS141, but for structural reasons there is no LAN socket at the UPS installation site. With the WiFi dongle you can permanently connect the CS141 to a WiFi and in this way transparently integrate it into a building management system.
The second approach is based on the fact that many users no longer want or are allowed to operate insecure SNMP solutions that are poorly integrated into the UPS in their network infrastructure. In this case, a CS141 serves as an "intermediary" - it can be connected directly via LAN to the third-party SNMP card, read out via RFC1628, and then independently forward this processed data via WLAN.

Note: 

Optimal versatility in network architecture and seamless integration with the WiFi dongle, the CS141 offers an independent 2nd network interface with which numerous network requirements can be served. From network separation to redundancy connections, this function offers multiple design options.
