Appendix A
Power Supply Specifications
Power Supply Redundancy
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
power supply is inserted
with redundancy disabled
System log and syslog messages are generated.
System power is increased to 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.
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.
