[c-nsp] Adding a SUP720-3BXL standby SUP question

[Brian Wallingford]

I wouldn't go that far unless you've got a use for an additional chassis.
Simply put the compact flash from the new 3bxl into the primary's 2nd
slot, copy the image & return it to the new card if you're nervous.
Either way, insterting a new sup should not interfere with the primary.
