1. GENERAL INFORMATION
1.1 Introduction
The Local Area Network (LAN) option for the HFE series power supply allows the user to
remotely program, measure and check status of the power supplies.
The LAN option is designed to communicate with single or multiple supplies in a rack
or with multiple racks housing HFE power supplies.
The LAN option is also designed to communicate with multiple racks, each rack holding
either HFE1600/S or HFE2500/S power supplies with PMBUS option.
The user can install and remove the HFE LAN module with no disruption to the operation
of the HFE power supplies.
A computer’s web page browser can be used to operate the module through a built-in
web page server. For applications including factory and test automation, communication
may be done using several standard network protocols and instrument commands.

s. Allows connecting up to 16 power supplies (or housing of 2 racks of HFE1600-S1U/
TB or HFE2500-S1U/TB).
t. One LAN IP address shared by all power supplies.
u. Can use combinations of HFE1600/S and HFE2500/S power supplies with the same
LAN module.

Note - If HFE LAN module is installed in the rack, +12V_AUX (pin 38 of J1 connector
on HFE/S1U rack) cannot be used as an auxiliary supply.

1.3 Front Panel View
The module front panel, is shown below.
Figure 1. LAN Front Panel
1. LAN Connector: RJ45, 8 pin, 10/100MBps and IEEE802.3 compliant.
2. Link/Activity LED: This LED, embedded in the RJ-45 socket, glows green and
blinks when the connection is made to an active network and packets are being
transmitted.
3. Speed LED: This Amber LED is ON at speed of 100MBps and OFF at speed of 10MBps.
4. LAN Status LED: There are two LED’s next to the RJ-45 connector. It shows:
• Normal Operation: Steady green. The module has an active LAN connection
• Device Identify: Blinking green. The identify function is turned on from a remote
computer using the web page or with command. It is used to identify one LAN module
in a rack of instruments. This will also blink if there is a duplicate IP. The blinking is
turned off by the web page or by sending a LAN specific command.
• LAN Fault: Steady red. Shows the LAN mode is not enabled, the LAN connection
was never made, or that the LAN connection was made and then broken.
5. Reset Switch: This switch resets the LAN to its default settings.
