LAN (Local Area Network) modules work with HFE series 1.6 kW and 2.5 kW rack mounted, hot swap power supplies. These optional modules allow remote monitoring, status check and programming through a number of standard protocols, supporting VISA (Virtual Instrument Software Architecture). The LAN option is suitable for computer networking, telecommunications, test and measurement and industrial equipment.
The modules plug into any open slot on the standard HFE1600 or 
HFE2500 19-in. racks, measuring the same size as the HFE1600 or HFE2500 I2C/PMBus equipped power supplies. Removal or insertion of the modules can be made with the ac input applied (to the HFE rack housing, HFE1600-S1U or HFE2500-S1U) without causing any disruption to the power supply output voltage. The HFE1600-LAN and HFE2500-LAN can be used with any of the available HFE output voltages and can support up to two racks, or their individual power supplies.
A computer’s web browser can be used to operate the modules through the built in webpage server. A Graphical User Interface (GUI) is built in to the web server and can be used to monitor the status of the power supplies. A password feature is provided to avoid unauthorized access.
The Ethernet RJ45 connection is on the front panel, along with a button to reset to default settings and status LEDs which can be made to flash to identify the LAN location. Network speed can be set manually or automatically to detect the fastest 10Base-T or 100Base-T network. IP address configuration can be manually set or automatically created.
The LAN modules are certified to IEC/EN/UL/CSA 60950-1 with CE marking for the Low Voltage and RoHS2 Directives.
