Context :on a R620 (out of warranty) with iDRAC problems, I'm trying to use this procedure. I need some clarifications/disambiguations in order to  be sure that I apply it correctly, because there's no visual feedback except for the LED status.

So, is there any limitations/requirements in terms of  :
  .type of card, ie does "SD Card" means standard SD Card (aka SDSC), SDHC or vFlash ?
  .filesystem, ie does "FAT" means FAT16 or FAT32 ?
  .size of card, like lower/upper limits in GB ?
  .location of the slot, ie does "Insert the SD card" means that the SD Card has to be  inserted in the "wrench" slot (on the front panel of the server in my case) or in an IDSDM (Dell Internal Dual SD Module) ?

Many thanks in advance for your enlightenments
