Sur un switch DCX où seule deux alimentations (sur 4) sont installées, le status des power supply passe en DOWN donc le switch entier… Ce qui peut remonter des alertes alors que tout est normal…
Ceci est dû au fait que le switch est paramétré pour avoir 4 alimentations. Lorsqu’il y en a que 3 il passe en MARGINAL et plus que deux en DOWN.
Il faut donc changer la limite d’alerte.
