Don't count your chickens...
... before having installed the hardware!
Or more precisely, I should not have announced the arrival of the new server for Watson before being sure that it was working... It seems that there was a little accident during the delivery, the server should have been dropped, leading to apparently superficial damages. Then, even though it seems only superficial, we cannot even check if it is working until someone from the constructor's company comes to test, and hopefully fix it...
That means at least one more week before we can start playing with our new toy... grrr :-(
