Logic Board Display on the 6780 Switch
You can use the liquid-crystal display (LCD) on the logic board of the 6780 switch to
help diagnose problems associated with the switch. Use the UP and DOWN buttons to
scroll through the display. Figure 3-9 shows the Switch Logic Board.
The LCD on the logic board contains this information (in the order shown):
•
The switch name and numeric selector setting
•
The group number and module number
•
The ServerNet node numbers supported by the switch
•
The fabric, zone, and layer of the switch
•
The VPROC string of the firmware image
•
The VPROC string of the configuration image
•
The VPROC string of the FPGA image
•
The logic board part number
•
The logic board revision level
•
The logic board tracking ID
•
The switch model number (6780)
Look for information that might reveal incorrect switch settings or configuration. For
example:
•
Check the numeric selector settings for corresponding X and Y switches to see if
they were accidentally set the same. For example, switch X12 and switch Y12
must have different numeric selector settings: the setting for Switch X12 should be
9612, and the setting for switch Y12 should be 9712.
