    Newbie question to infiniband: Stuck with IS5022Q shutting off during initialization

    dsmvousa

      Hello,

       

      I just acquired the following [used] switch:

           P/N MIS5022Q-1BFR Rev:A5

       

       

      Within a few seconds from plugging in and showing green for both system and fan LEDs, the switch shuts itself off, leaving only the fans running.  It will repeat that when unplug, rest 5-minutes, and replug, with or without port cablings.  Since I can't get a stable inband connection to attempt dumping out any information, I would like to know whether it could be in certain bad state that can be fixed by reset (if possible), or the switch will no longer be useable.

       

       

      Below is more details

       

      Without any port cables:

      - Plug in

      - Green LED show green in port#2 and port#6 briefly.  Other port LEDs are off

      - System LED and Fan LED turn green

      - Within 1-2 seconds (varies), all LEDs turned off

      - All Fans are still running until unplugged.

       

       

      A similar pattern is seen when there're cables connected from ConnectX-2 cards (MHGH19B_XTR and MHQH29B_XTR).  Though not always repeatable, at some point I got the switch shortly recognized by discovery before it shuts itself off as seen in [edited] log below

      Switch   : 0x0002c90xxxxx90b8 ports 8 devid 0xbd36 vendid 0x2c9 "Infiniscale-IV Mellanox Technologies"

       

      Room temperature is about normal 68-72F, and I don't feel or see anything that suggests the switch may be overheated (other than the internal of it).  I tried a couple of different power sockets and that did not make any difference.  The manual suggests to get the reason the switch shuts off from management software; with a link down and the switch is externally managed, how can I go about that?

       

      I appreciate if you can give me some advise as where I may go from here.

       

      Thank you very much!
