    errdisable_recovery.pdf explains why our HP-Blade suddenly has disabled port (turn red light from initial green) when connected to a switch.

    1
2
3
4

    #show interfaces gigabitethernet 4/1 status
 
Port    Name       Status       Vlan       Duplex  Speed Type
Gi4/1              err-disabled 100          full   1000 1000BaseSX
