Provide power to the MSS.
Attach one end of the power cable to the MSS and plug the other
end into a wall outlet. There is no power switch on the MSS;
power will come on automatically when the unit is plugged in.
At this point, there is power to the server, so be sure to use
appropriate care when handling the unit.
NOTE:
Ensure that you are using the MSS six volt power supply. The
Lantronix EPS1, EPS2, and LRS2 units have a power supply that
looks similar to the MSS power supply, but is a different voltage.
Using the wrong power supply with the MSS will damage the MSS.
Check to see if the Power and Link LEDs on the front of the server
light. If not, unplug the server and check the power supply, then
check the Ethernet connection and plug the server in again. If the
LEDs still do not light, refer to Appendix B,
Troubleshooting

2.2.1 Power-up Diagnostics
The MSS boot-up procedure consists of three steps. During normal
operation, the boot process requires approximately 30 seconds to
complete.
1.
The MSS runs through a set of power-up diagnostics for
approximately five seconds. The Power LED should remain
solid green; the OK and Serial LEDs should show varying
patterns corresponding to the test being run.
NOTE:
The Power and Link LEDs should be solid green if the unit is plugged
in and there is a valid connection to a 10BASE-T network.
2.
The MSS tries to obtain TCP/IP configuration information via
BOOTP and RARP. This procedure takes approximately 20
seconds if no hosts answer the request. During this step, the OK
LED blinks green approximately three times per second, and
occasionally yellow as packets are sent and received.
NOTE:
For more information on BOOTP and RARP, refer to your operating
system’s documentation.
3.
The MSS determines if the code in the Flash ROMs is valid. If so,
it loads the code and begins normal execution. This step takes
approximately five seconds.
