Product and Software: This article applies to all Aruba controllers.
Variation in the voltage rate indicates a hardware issue with the controller.
To troubleshoot, get the output from the "show inventory" command several times.
For example:
(Aruba3200) #show inventory
Supervisor Card slot : 0
System Serial# : AC0001110
SC Assembly# : 2010029B (Rev:02.00)
SC Serial# : F00681754 (Date:01/15/08)
SC Model# : A3200
HW MAC Addr : 00:0B:86:61:1F:58 to 00:0B:86:61:1F:D7
CPLD Version : (Rev: 1.1)
A3200 Card Temperatures :
: Card Temperature 38 C
: CPU Temperature 46 C
A3200 Fan Tachometers :
: Chassis Fan A 4067 RPM
: Chassis Fan B 4000 RPM
: Chassis Fan C 4000 RPM
: Chassis Fan D 4137 RPM
A3200 Card Voltages :
: VMON1 3300mV 3324 mV
: VMON2 2500mV 2550 mV
: VMON3 AB 1800mV 1812 mV
: VMON4 CD 1800mV 116 mV
: VMON5 1200mV 1222 mV
: VMON6 1000mV 1006 mV
The VMON outputs are treated as two separate groups:
• Higher voltage 2.5 and 3.3 - delta from norme +/- 20mV
: VMON1 3300mV 3324 mV
: VMON2 2500mV 2550 mV
• Lower voltages 1.0, 1.2, 1.8 and 1.8 - delta from norme +/- 10mV
: VMON3 AB 1800mV 1812 mV
: VMON4 CD 1800mV 116 mV
: VMON5 1200mV 1222 mV
: VMON6 1000mV 1006 mV
Ideally, two probe commands would be run, and you would look at the delta from the two responses. The delta should not be greater than 10 mV for the 1.8V, 1.2V, and 1.0V supplies. For the 2.5V and 3.3V supplies, the delta should not be greater than 20mV.
With just one reading, the value could fall within a 3% limit and you would not flag that it had an oscillation problem.
For the 2.5V and 3.3V supply voltage check, the limit range should be +/-5%.
Contact the technical support center, because the controller needs to be replaced due to this hardware failure.
