7.7 Restoring Power After Emergency Cab Shutdown
This section provides the procedures to restore power to each of the extended
cabs after the master cab has been powered off by an “emergency cab
shutdown”. Examples causing this type of shutdown would be fan loss or
power-supply loss, etc.
It is recommended that the extended cabs be powered off and powered back on
prior to the reboot of the master cab. The steps to follow are:
1.
Power off remaining (extended) cabs.
2.
Power up extended cabs.
3.
Power up Master Cab.
There are two procedures that may be used to accomplish the above three
steps. Compaq recommends the first procedure.
7.7.1 Using AC switch
1. Turn off AC switch after EMU alarm sounds on extended cabs.
2.
Turn on AC switch on extended cabs.
3.
Turn on AC switch on Master Cab.
7.7.2 Using EMU/PVA
1. On extended cabs, wait for EMU alarm to sound, turn off EMU alarm,
then press and hold PVA switch until the cab shuts down.
2.
Press EMU button on extended cabs.
3.
Press EMU button on Master Cab.
