Hi,

I have a peculiar issue with a router whering I get the message in the Show Environment as below.

sh environment out

Redundant Power System is not present.

SYS PS1 is present.

    Type: AC

AUX(-48V) PS1 is absent.

Fan  1 OK

Fan  2 OK

Fan  3 OK

Fan Speed Setting: Normal

Alert settings:

Intake temperature warning: Enabled, Threshold: 55

Core temperature warning: Enabled, Threshold: 70 (CPU: 95)

Board Temperature: Normal

Internal-ambient temperature = 22, Normal

CPU temperature = 37, Normal

Intake temperature = 22, Normal

Voltage 1(3300) is Normal, Current voltage = 3300 mV

Voltage 2(5150) is Normal, Current voltage = 5210 mV

Voltage 3(2500) is High/Low, Current voltage = 2168 mV

Voltage 4(1200) is Normal, Current voltage = 1215 mV

Appreciate a reply on this.

That usually means that it has the capability for a second power supply, but it's not installed

Hi charu,

No more furthershooting for this :-)

Straight away go ahead and raise the RMA to get the device replaced.

Hi Steven/Inayathulla,

As per the logs the issue seems to be with the power. Would replacing the power supply do any good?

Thanks

[Steven Clinton]

I do not see a hard fault in the data you have provided, I only see that the thresholds are being exceeded. I would have someone verify the power and compare it to another device connected to the same power source.

Hope that makes sense
