Cisco CATALYST 6509E 9 SLOT 15U CHASSIS NO POWER SUPPLY NO FAN TRAY Guia De Especificação

Equal wattage power 
supply is inserted with 
redundancy disabled

System log and syslog messages are generated.

System power is the combined power capability of both supplies.

The modules marked as power-deny in the show module Status field 
are brought up if there is sufficient power.

Higher wattage power 
supply is inserted with 
redundancy enabled

System log and syslog messages are generated.

The system disables the lower-wattage power supply; the 
higher-wattage supply powers the system (Catalyst operating 
system). 

For Cisco IOS, both power supplies come on. The total available 
wattage is the output wattage of the higher wattage power supply.

Lower wattage power 
supply is inserted with 
redundancy enabled

System log and syslog messages are generated.

The system disables the lower-wattage power supply; the 
higher-wattage supply powers the system (Catalyst operating 
system).

For Cisco IOS, both power supplies come on. The total available 
wattage is the output wattage of the higher wattage power supply.

Higher or lower wattage

supplies.

The modules marked as power-deny in the show module Status field 
are brought up if there is sufficient power.

Power supply is removed 
with redundancy enabled

System log and syslog messages are generated.

If the power supplies are of equal wattage, there is no change in the 
module status because the power capability is unchanged. 

If the power supplies are of unequal wattage and the lower-wattage 
supply is removed, there is no change in the module status. 

If the power supplies are of unequal wattage and the higher-wattage 
supply is removed, the lower-wattage power supply must be turned on 
manually. (The system had previously turned off the lower-wattage 
power supply.)

Power supply is removed 
with redundancy disabled

System log and syslog messages are generated.

System power is decreased to the power capability of one supply.

If there is not enough power for all previously powered-up modules, 
some modules are powered down and marked as power-deny in the 
show module Status field.
