Appendix A Power Supply Specifications Power Supply Redundancy Table A-22 Effects of Power Supply Configuration Changes (continued) Configuration Change Effect 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 • System log and syslog messages are generated. with redundancy disabled • 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.
