Status -> slot m M3-MONITOR

Clicking on slot m M3-MONITOR will display the following information for the monitoring line card.

This webpage for the M3-MONITOR monitoring line card is subdivided into categories: general information, uc, and M3-MONITOR. Each section/category contains a variety of counters and state bits related to the operation or health of the monitoring line card. 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 monitoring line card.
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 monitoring line card.

state -- the operational state for the monitoring line card.
resets
firmware faults
overtemps
reboot: <n>

This clickable variable hyperlinks to a webpage to reboot the microcontroller on this switch line card, 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-MONITOR section provides information on the individual components of the monitoring line card.

shutdown: <n>

This clickable variable hyperlinks to a webpage to shutdown this switch line card, or all of the switch line cards.

Checking the shutdown box and clicking on Apply on this webpage will set this <n> state bit value to 1 and trigger the shutdown of the selected switch line card(s).

If this <n> state bit has a non-zero value, the the microcontroller on the switch line card is in the SHUTDOWN state. If the value is set to zero, the microcontroller goes to the SELF-TEST state, and if the test is successful, it then goes to the OPERATING state.
refreshes

This counter specifies the number of times the output for the monitoring line card has been refreshed.
uptime

This counter specifies the amount of time (in seconds) since the monitoring line card was rebooted.
firmware -- the version of the switch firmware currently running on the monitoring line card.
ip address -- the IP address of the monitoring line card.
hw address -- the MAC address of the monitoring line card.
voltage a indicates the main voltage coming into the line card from the switch chassis. The value of this voltage should be 0 - 13.2V.
voltage b -- can be ignored.
The voltages voltage 0 through voltage 3 indicate a number of individual voltages measured at various locations on the line cards. The number of voltages measured, and their precise values, vary depending on the type of line card. (The customer will rarely (if ever) need to look at these values.)
temperature 0 and temperature 1 -- the inlet and outlet temperatures, respectively, for the monitoring line card. The temperatures are measured in degrees Celsius. For example,

and
current

This clickable variable hyperlinks to a webpage to determine if a power fluctuation in the electrical current has occurred.

The following state bit and counter are on this webpage.
- over current fault
  
  This state bit has the following values:
```
over current fault: 0 if circuit breaker has not tripped
                    1 if circuit breaker has tripped
```
- over current count
  
  This counter indicates the number of times that the value of the over current fault state bit has toggled between 0 and 1.
- current -- measured in mA
  
  This variable is measured in mA. If the switch line card is in the OPERATING state, the value of this variable indicates the electrical current being drawn by the switch line card. If over current fault has been tripped, the value indicates the electrical current that was being drawn at the time it was tripped.

operating led

This clickable variable hyperlinks to a webpage to modify the behavior of the status LED on the switch line card.

This webpage lists the following state bits.

led state: <n> (<color>)

The values of <n> and <color> are as follows:

led state: 0 indicates LED is off
           1 indicates LED is fault (amber)
           2 indicates LED is operating (green)
           4 indicates LED is blinking green
           5 indicates LED is blinking amber
           6 indicates LED is blinking amber/green

force led: <n> (<color>)

This clickable variable hyperlinks to a webpage to modify the behavior of the status LED on the switch line card.

If force led is nonzero, the LED is in the state specified by force led, and led state indicates what state the LED would be in if force led is zero.

force led: 0 indicates LED handled by uC
           1 forces fault indication (amber)
           2 forces operating indication (green)
           3 forces LED to be off.
           4 forces LED to blink green
           5 forces LED to blink amber
           6 forces LED to blink amber/green

backplane type -- state bit indicating the type of switch chassis. 1 indicates M3-CLOS-ENCL, and 2 indicates M3-SPINE-ENCL.
