Plugging in redundant on-board power supply

[Patrick McHenry]

HI,

Is it possible for me to plug in and turn on on-board redundant power supply for a 4402 WLC that is already online and in production without any disruption to Wireless users and APs attached to that same controller?

Thanks, Pat.

That power supply should be hot swappable.  But as with anything having to do with power, you are better served by taking the system down.  that way you can avoid any arcing.

HTH,

Steve
