Reset Button
A pin hole is provided in the faceplate of the Network card to access the reset button
using a paper clip or similar device. The reset behavior of the Network card is provided
below and is dependent on the duration of the button press.
Reset the NMC when it does not respond: Hold the reset button for 2 seconds and
release when green LED starts flashing. This will cause a reset of the NMC controller,
but the entire configuration will be retained.
Reset all configurations to a factory default setting: Hold the reset button for at least 20
seconds and release when green LED starts flashing fast. This will cause a reset of the
NMC controller and all configurations to be erased, including the usernames and
passwords.
Micro-B USB Connection
The USB connector provides a COM port connection for configuration via a command
line interface (CLI) to the Network card.
Refer to the Network card User’s Manual for more details on the operations of the
Network card.

remove the Relay card from the UPS unit.
