PSU showing Power save and overall status : N/A

Hi,
In UCS chassis 5108,we noticed a 2 PSU was faulty to check properly  we swapped a cable and one of the PSU came up but another PSU was on same status. so we raised PSU and replaced it, but the overall status of the PSU was N/A and its not glowing green LED. Its blinking the Green LED but not continuous glow.
Please find the attached snap.

Hi Anandraj,
What´s your configuration on power groups and firmware version? N+1 or Grid?1.x or 2.x?
The Blinking green led and status power-save,  I belived this one is a standby.
When you configure N+1, two PSU work and one Standby mode then If you configure Grid all PSU work together and all Green LED  are glowing.
Follow below documantion with Power Group configuration:
http://www.cisco.com/en/US/docs/unified_computing/ucs/sw/gui/config/guide/141/UCSM_GUI_Configuration_Guide_141_chapter29.html#concept_B17F97D8074A4CB590309E3E8C8DD9F9
PS:
I found this information below, too.
The power supply is providing no power to the system but can be powered up
quickly in the event of another power supply failing. This mode saves power
in two ways:
1. It reduces the power consumption of the PSU, as there is no output the PSU
only requires a small amount of power to keep the capacitors charged and
circuitry active.
2. It increases the load on the remaining PSUs shifting them further on their
efficiency curves.

  • PSU in power-save state

    Hi,
    we have some UCS-B and some leds of their PSU's are blinking and the status is N/A. Status detailed can be seen in the screenshot:
    The strange thing is this state doesn't generate any fault.
    Does anyone know if PSU's are really working bad or is only a cosmetic issue?
    Regards.

    Had the same "problem" before.
    When I passed a chassis the blinking PSU got my attention.
    Our Cisco SE told me that this is a normal behaviour. When a PSU is not needed (depends on your power policy and installation order) it is switched to standby/power-save.
    Nothing to worry about. Just a "green" behaviour.

    Hi Tarun 49,
    If you are having issues with your iPhone such as you describe, you may want to try some things to troubleshoot.
    First, quit all running applications and test again -
    iOS: Force an app to close
    Next, I would try restarting the iPhone -
    Turn your iOS device off and on (restart) and reset
    If the issue is still present, you may want to restore the iPhone as a new device -

  • I phone 4 screen just showing power cord and i tunes logo after doing an update

    Tried to do an update on my Iphone 4.  Now the only thing showing on my screen is a picture of the power cord and the I-tunes logo.  I can't power it off or on.  I have tried holding down both buttons but nothing happens.

    You need to restore the device.

  • What is Safari Power Saver and why does it keep popping up?

    On many sites I get a popup asking me to activate or install Safari Power Saver. I sometimes close the popup, more often just leave the site. Is there any danger to clicking ok? Is there any reason to do this? Is there any way to avoid this without turning off popups everywhere?
    Thanks!
    Stan

    Thanks! I still don't understand the concept of "saving power" in this context. Does that relate to a laptop running on battery, and some popups consume more battery power? Or does this refer to CPU capacity?  I have never had any issue that I know of in these areas. I would understand the warning if it cautioned me about insufficient bandwidth, but that doesn't seem to apply here. In any case, am glad to find that this is a feature and not a bug.

  • 6210 Nav. power save and light

    Hi guys,
    wonder if someone could assist me is a couple of newbie questions with the 6210 Navigator.
    1 - Can I prevent the screen from dimming and going into power save? i.e. Keep the screen on permanently while using the Navigator / Sat Nav function.  I would like the power save still to be enabled for normal use but its a bit annoying when the screen dims out after 30 seconds when trying to use the Sat Nav.
    2 - Is it possible to use the camera flash as a torch?  I would like to be able to switch the light on and off and use it as a torch.
    Many thanks,
    Steve

    I dont know how did you install the Toshiba tools but after the OS installation you have to install the chipset utility and then the Toshiba common modules. After the installation of 2 important drivers follow the installation with display driver etc

  • Windows Screen Saver and Monitor Status

    How do I communicate to windows to find the Windows screen saver status and the monitor status?
    Tim

    I don't know the particular API calls you need for that, but here's the general way to access Windows innards:
    Use the CALL LIBRARY function, and point it to ADVAPI32.dll.
    This particular call is set up to call "GetUserNameA", returning the logged-in user's name.
    If there's an API for what you need, then configure this function to go call it.

  • Run script to background wo/ showing the pid and done status [SOLVED]

    I have a little script I wrote that I execute in my ~/.zshrc that I would like to run in the background without printing out the pid of the background process and the done status.  Is this possible?
    Example:
    << ~/.zshrc is sourced and it runs this line>>
    << ~/bin/check& >>
    [1] 13047
    grtaysky@host ~ %
    [1] + 13047 done ~/bin/check
    What I want to see is:
    << ~/.zshrc is sourced and it runs this line>>
    << ~/bin/check& >>
    grtaysky@host ~ %

  • My 4500 all in one goes into power save and will not come out of it without pulling the power plug.

    I have tried hitting the power button short and long, pushing every button, but it seems the only way out is pulling the power plug.
    Thanks for any help.

    HI
    This is a known issue and HP is working on Firmware to fix this issue. This will be released soon.
    So please use the workaround for the time being if the printer goes to power saving mode.

  • 6300 power saver & sleep mode

    Hello,
    My problem is that after only one week that passed after I bought a Nokia 6300 my power saver and sleep mode stopped working. I tried turning them on and off or even put one on "off" and the other one "on" but it seems they just stopped activating.
    Did anyone encounter this problem or know how to solve it, because it's anoying to have always the phone in idle mode.
    Thank you in advance.

  • Power save function on N8

    Hey people,
    Been doing a few tests recently with power save and I've come to a conclusion that it's rubbish and shouldn't be used. Sorry if this is old news but I had a quick search and couldn't find anything.
    My phone basically lasted just under 2 days with light usage activating power save when I went to sleep. Went to bed with a full battery, woke up with 1 bar gone!
    I then did another full charge and didn't use power save at night. I have just charged my phone after almost 6 days, again with light usage. 5-10 texts a day, checking email, football results etc a few short phone calls and a bit of camera use plus watching video's I have recorded!
    So what's up with that then? Power save my a**e.
    At first I thought it was nokia battery monitor doing it so I un-insatalled it. I have just re-installed it and am going to test now to see if can last another 5-6 days. I guess it depends on my usage. Battery monitor is quoting me just over 2 days usage time.
    5-6 days usage time for a smart phone though is awesome. I have to congratulate Nokia for that.
    Ben

    The reason I cannot give a solution on the forums is because this particular solution requires a phone interaction.  It is not something that can be done on the forums due to the nature of the solution and collecting personal information that is not allowed to be displayed on the forums for all to see. 
    It is more or less for the protection of the users that I am not able to provide a solution in a public forum.

  • Nokia 6233 - screen awakes from Power Save / Sleep...

    I have Power Save and Sleep Mode on, but ScreenSaver off.
    However, the screen often awakes from PowerSave / Sleep (not sure which - manual doesn't describe the difference) and lights up.
    This is especially annoying when driving and the Nokia is on a hands-free mount: it's quite distracting, and occurs about every couple of minutes.
    It may be that when driving, I'm moving between different signal strengths, and that change to the powersaved screen display activates it again. But it has also happened with the phone in a building.
    Any suggestions welcome

    I have exactly the same problem, as do several colleagues. It's also very distracting when it sits on a bedside cabinet, lighting up the bedroom every few minutes in the middle of the night. Sadly I have no suggestion - just want to get this topic higher up the heirarchy so that maybe someone who knows an answer will spot it more easily.
