   A Metro Node system has two directors. The System Health check reports: Director 1 - 'OK', Director 2 - 'Warning: Temperature above threshold', Backend Connectivity - 'OK', Frontend Connectivity - 'OK'.

   • AFail over all I/O to Director 1 and shut down Director 2.
   • BIgnore the warning since the ambient temperature is normal.
   • CReplace Director 2 immediately to prevent thermal damage.
   • DCheck the director's cooling fans and air filters for blockage or failure.
