Features of the TFT Color Display

Note that this interface may be modified in the future and this information only reflects the current state of the software.

As described in the FAQ entry (http://www.myri.com/cgi-bin/fom?file=374), when the 10G-CLOS-ENCL switch is powered on, the Color-TFT Display (driven by the monitoring line card) will illuminate and have a color-bar display. After the operating system finishes booting (about 10 seconds), the color-bar display will redraw into a virtual image of the switch. (See image below.) The Display Control Knob on the monitoring line card controls the TFT display, and can be used to input settings.

As an example, we will examine the TFT Display of a 10G-CLOS-ENCL switch containing four 10G-2SW16LC line cards, one 10G-SW16LC-6C2ER line card, and four 10G-SW16LC-8C switch line cards.

The first screen that we will see on the TFT display represents a virtual image of the switch line cards in the enclosure (not including the monitoring line card.) Since the switch line cards are inserted vertically into the switch chassis, each column of the image in the TFT display represents a specific switch line card (or slot) in the switch chassis. The circle at the top of each column indicates the Status LED for the switch line card. The square boxes in each column indicate the switch ports. If the column is blank, this slot in the switch enclosure does not contain a switch line card. If the column only contains the Status LED at the top of the column, but no switch ports indicated, then the switch line card does not contain any switch ports. For example, slots 8-11 contain the four 10G-2SW16LC spine line cards.

At the top-left corner of this virtual image, we see the words face, log, big_uc, and net.

• face

  face indicates the screen that shows the virtual image of the switch (with lights to indicate which ports are active).

  This format allows selecting an item (box) by turning the Display Control knob to the desired item and pushing on the knob to select it. Details are below.

• log

  Selecting log on the top-level screen will show the log of all events. Selecting one of the events will show more information about the switch when the event occurred.

  Once a log is selected, a localized data screen is displayed. Selecting back in the top-left corner of the screen will bring us to the screen for that slot. Another back will bring us back to the virtual-switch screen, with the slot of this log highlighted. (With the web browser, a filter can be modified to collect only certain event types).

• big_uc

  Selecting big_uc provides information on the monitoring Line card.

• net

  Selecting net allows you to assign a static IP address to the monitoring line card.

• Note: There is a refresh field in all of the TFT images except face because only face updates itself automatically in real time. The text screens are only up-to-date when they are loaded.

face

The face option on the TFT Display displays a virtual image of the connectivity of the cluster.

Each column of the image represents a specific switch line card (or slot) in the switch chassis (excluding the monitoring line card). The circle at the top of each column indicates the state of the Status LED for the switch line card, and the eight squares underneath correspond to the status of the eight switch ports on the switch line card. If the column is blank, this slot in the switch enclosure does not contain a switch line card. If the column only contains the Status LED at the top of the column but no switch ports indicated, then the switch line card does not contain any switch ports. For example, slots 8-11 contain the four 10G-2SW16LC spine line cards.

The color of the Status LED indicates the operational state on the switch line card.

• A green LED indicates that the switch line card is powered on and operational.
• An amber LED indicates that the switch line card has shut itself off. This could occur if the switch line card has overheated, or failed its self-test. Check the switch line card data to provide more details on the problem. (See details below.)

Note: It is also possible to change the color of the Status LED on the switch line card using the web interface to the switch. (Specifically, this can be done by selecting the force led command under the operating_led option for each line card.) This is a particularly useful feature for debugging. Thus, if a status LED is illuminated in amber, we should check the setting for the LED to make sure that the color was not modified via the web interface. If the status LED is not illuminated in green, also make sure that this is the proper switch line card for this slot in the enclosure, and if so, try reseating the switch line card in the slot. For further details, refer to the specifications for the 10G-CLOS-ENCL switch.

Underneath each virtual Status LED light are eight squares, corresponding to each port on the switch line card. The color of the square indicates the connectivity status of the switch port as follows:

• green: If the square is illuminated in green, the switch port is connected and idle.
• amber/yellow: If the square is illuminated in amber/yellow, the switch port is connected and there is traffic (messages being sent and received) through that switch port.
• clear/transparent: If the square is transparent, the switch port is disconnected.

If the column of eight squares corresponds to quad-link ribbon-fiber ports, each square will be subdivided into 4 quadrants. Each quadrant is associated with one of the 4 fibers in the quad port as follows.

0 1
2 3

All of the connected switch ports on the TFT display should be illuminated in green (or yellow if there is traffic).

If some of the connected switch ports are not illuminated in green or amber/yellow, please follow the steps outlined in Appendix: Common Maintenance Procedures to diagnose the problem.

Note: Be aware that when looking at the TFT display from below, the color yellow may appear red. Red is not a color in use on the TFT panel.

How to Select a Switch Port

To obtain more information on a specific switch port, first turn the Display Control Knob (located on the monitoring line card) clockwise until the desired column in the virtual switch has been reached, and then push the knob to select this virtual line card. After the knob has been pushed, the Status LED circle at the top of the column will be highlighted. Turn the Display Control Knob again to scroll through the rows on the display to select a specific port on that switch line card. Push the knob to select the port, the port will then be highlighted, and then a new TFT display screen containing the current state of the port will appear.

For example, let's examine a 10GBase-CX4 port on a 10G-SW16LC-8C line card.

cx4 port

From the TFT Display, select face, and turn the Display Control Knob clockwise until you reach slot17, containing a 10G-SW16LC-8C line card.

If any of the following switch counters report a non-zero value, then click on its name below to be forwarded to the glossary for its definition and a list of possible explanations for a non-zero value.

• signal lost

• signal lost count

• self test result

• control

  The control button is not yet activated for the TFT display.

Clicking on back in the top-left corner of this screen will jump to the full switch line card information (including the firmware version and the serial number).

Selecting back again will jump to the virtual switch image level.

big_uc

Clicking on big_uc on the top-level TFT screen will yield:

The following counters are listed:

• refreshes

  This counter specifies the number of times the output for the monitoring line card has been refreshed since its last reboot.

• 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 the voltages measurements from four different locations on the monitoring line card. (The customer will rarely (if ever) need to look at these values.)

• The two temperatures (temperature 0 and temperature 1) indicate the inlet and outlet temperature respectively on the monitoring line card. If you click on temperature 0, you will see:

  

  which represents the inlet temperature for the monitoring line card. The outlet temperature can be obtained by clicking on temperature 1. The optimal range of temperature for the switch components should be in the 20s degrees Celsius. Shutdown to avoid hardware damage will occur at 55 degrees Celsius.

• If you click on current, you will see:

  

  The measured electrical current should be in the range of ... .

• If you click on operating_led, you will see:

  

  The led state: 2 indicates that the color of the Status LED for the monitoring line card is green. The color of the LED can only be changed via the web interface.

net

Clicking on net on the top-level TFT screen will yield:

Dial the turn-push knob to the desired digit to be modified, click on the digit, and then dial the turn-push knob until you see the correct number. Click to assign that number to the digit. Repeat for each digit in the IP address and the netmask. Enable static addressing by setting enabled to yes, and then click done to return to the main tft display menu. Connect at least one of the ethernet ports to the LAN, and reboot the monitoring line card (or power cycle the switch). When the monitoring line card comes up again it will skip the DHCP step and use the assigned IP address and netmask.
