Status -> slot 23 M3-POWER

Clicking on slot 23 M3-POWER will display the following information for the power supplies.

This webpage for the M3-POWER power board is subdivided into categories: general information, uc, and M3-POWER. Each section/category contains a variety of counters and state bits related to the operation or health of the power board. As a general rule, a non-zero value for a state bit or counter should be investigated as it may indicate an abnormality in the functioning of the hardware.

Click on the name of the counter/state bit below, and the hyperlink will forward to the glossary for its definition and a list of possible causes for the non-zero value.

The general information section of the webpage includes:

• lost communication

• lost communication count

• serial number -- the serial number for the power board.

• engineering date code -- internal Myricom manufacturing information.

• firmware version -- internal Myricom use.

• monitor version -- internal Myricom use.

• changes

The uc section provides information pertaining to the health of the microcontroller on the power board.

• state -- the operational state for the power board.

• resets

• firmware faults

• overtemps

• reboot: <n>

  This clickable variable hyperlinks to a webpage to reboot the microcontroller on the power board, or the microcontrollers on all of the switch line cards.

  

  Checking the reboot box and clicking on Apply on this webpage will set this <n> state bit value to 1 and trigger the rebooting of the selected microcontroller(s).

The M3-POWER section provides information on the four power supplies on the power board.

• power supply 0 through power supply 3

  Clicking on power supply 1 will reveal the following state bits and counters related to the operation of this power supply.

  

  Click on the name of the state bit or counter below and the hyperlink will forward to the glossary for its definition and a list of possible causes for the non-zero value.

  • ac bad

  • ac bad count

  • dc bad

  • dc bad count

  • off: <n>

    This clickable variable hyperlinks to a webpage to turn off the power supply. The switch firmware will prevent more than one power supply being off at the same time.
