System Events
The following paragraphs describe the typical information that can be displayed on the RMD screen.
Communications Fault Screen – If a communication issue occurs between the RMD and the UPS the
message shown in Figure 6 will be displayed. Check the state of the Ethernet 10/100 (RJ45) connection
examine both LEDs on the RMD. One represents Activity (ACT) and the other represents the speed (10/100)
at which that activity is occurring. Specifically, network communication is occurring when the green ACT
indicator is blinking. If this indicator is not illuminated then there is no network activity. The other LED
represents the speed of the network connection. If this indicator is illuminated yellow then that indicates a valid
100 Mb connection. If this indicator is not illuminated it indicates a valid 10 Mb connection as long as the
corresponding ACT is blinking green.
If the Activity LED on the RMD is not blinking green, check that the network cable is the correct type and
securely connected to the Ethernet 10/100 port for both the PXGMS card and the RMD.
If the network cable is securely connected to both the PXGMS card and the RMD, and display on the RMD is
completely white (i.e. no communication), communication can be reattempted. To re-establish communication:
1. Unplug the microUSB power connection from the RMD.
2. Turn the RMD off by holding the power pushdown switch down for 11 seconds.
3. Remove and re-seat the PXGMS card within the mini-slot and waiting approximately two minutes until the
Status indicator is illuminated.
4. Once illuminated, turn the RMD back on by re-inserting the microUSB power connection into the RMD.
After 55 seconds check to see if communication has been established with between the PXGMS card and
the RMD.
