Problem/Message

Error

Remedy

The MSS completes its power-up and boot procedures, but thereÕs no noticeable serial activity.

There is a problem with the serial connection or the set- up of the serial device.

A rapidly-blinking OK LED may signal boot failure.

Check the terminal setup and the physical connections, including the cable pinouts (see Appendix C). Try another serial device or cable, or cycle power on the MSS.

Reboot the unit. When the MSS is running normally, the OK LED blinks every two seconds.

The terminal shows a Boot> prompt rather than a Local> prompt.

The MSS is not connected properly to the Ethernet.

The MSS Ethernet address is invalid.

Ensure that the MSS is Þrmly connected to a functional and properly-terminated network node.

The MSS Ethernet address is located on the bottom of the unit. Use the Change Hardware command to set the correct address (see page B-5), then reboot.

The MSS passes power-up diagnos- tics, but attempts to download new Flash ROM code from a network host.

Init Noboot command was entered.

If the OK LED blinks rapidly, the Flash ROM code may be corrupt.

If you did not request a NetWare or TFTP boot, the ßash ROM code is corrupt. The unit will remain in boot mode.

See Entering Commands at the Boot Prompt on page B-4.

Reboot the unit. If you get the same message, you will need to reload Flash ROM. See Reloading MSS Software on page D-3.
