Power Supply Redundancy
Catalyst 6500 series switching modules have different power requirements. Depending upon the wattage 
of the power supply, certain switch configurations might require more power than a single power supply 
can provide. 
The Catalyst 6500 series switches can use two power supplies to function in either combined or 
redundant mode. The following table explains the differences between the two modes.

  Power Supply Redundancy
Although the power management feature allows you to supply power to all installed modules with two 
power supplies, redundancy is not supported in this configuration. Redundant and combined power 
configurations are summarized in Ta b l e A - 4 3. The effects of changing the power supply configurations 
are summarized in Ta b l e A - 4 4.
NoteFor proper load-sharing operation in a redundant power supply configuration, you must install two 
modules in the chassis. If you fail to install two modules, you might receive spurious OUTPUT FAIL 
indications on the power supply.
NoteIn systems that have two different sized power supplies installed, you may not have true redundancy. If 
the larger wattage power supply fails, the smaller wattage power supply might not be able to handle the 
entire load by itself.If one power supply fails, the second power 
supply can power the system on its ownIf one power supply fails, the other power supply 
may not be able to power the system on its own 
and will shut down the devices or line cards
This is the default and the recommended 
configuration for the power suppliesThis is not the recommended mode for production
Table A-42 Power supply modes
Redundant mode Combined mode
Table A-43 Power Supply Redundancy
If you have two 
power supplies of and redundancy is  Then
Equal wattage Enabled The total power drawn from both supplies is never greater than the 
capability of one supply. If one supply malfunctions, the other supply 
can take over the entire system load. Each power supply provides 
approximately half of the required power to the system. Load sharing 
and redundancy are enabled automatically; no software configuration is 
required.
Unequal  wattage Enabled Both power supplies initially come online. If the difference between the 
two power supply’s output wattage is less than 10 percent of the higher 
output wattage power supply, redundancy is enabled. If the difference 
is greater than 10 percent, the lesser wattage power supply is disabled.
For Cisco IOS, both power supplies come on. The total available 
wattage is the output wattage of the higher wattage power supply.
Equal or unequal 
wattageDisabled The total power available to the system is approximately 167 percent of 
the lower-wattage power supply. The system powers up as many 
modules as the combined capacity allows. If the higher-wattage power 
supply fails, the lower-wattage supply might also shut down due to 
overcurrent protection to prevent damage to the lower-wattage power 
supply.

  Power Supply Redundancy
When running redundant 4000 W, 6000 W, or 8700 W power supplies in Catalyst 6506 and 
Catalyst 6509 non-E series systems, if you remove the power supply in bay 1, the total system power 
will be reduced to 2940 W (70 A at 42 VDC) after 180 seconds (3 minutes). You can avoid this reduction 
in the total system power by leaving the power supply in bay 1, even in a powered down state.
If the total system power usage is greater than 2940 W, the following scenario will apply if a 4000 W, 
6000 W, or a 8700 W power supply is removed from bay 1 (these scenarios are specific to only these 
three power supplies running in redundant mode in either the Catalyst 6506 or Catalyst 6509 non-E 
series systems).
If the power supplies in bay 1 and bay 2 are running in redundant mode, the total system power will 
be 4000 W.
If power supply 1 is running and you power off or remove power supply 2, the total system power 
will be 4000 W. The system will issue a normal power supply 2 down/remove indication warning. 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. 
System is booted with 
power supplies of different 
wattage installed and 
redundancy enabled
System log and syslog messages are generated.
If the system power used is more than 83% of the higher wattage 
power supply capacity, the lower wattage power supply shuts down. 
The system will operate in redundant mode, with only higher wattage 
power supply.
If the system power used is less than 83% of the higher wattage power 
supply capacity, the lower wattage power supply comes online. The 
system will operate in non-redundant combined mode, with both the 
power supplies.
System is booted with 
power supplies of equal or 
different wattage installed 
and redundancy disabled
System log and syslog messages are generated.
System power equals the combined power capability of both supplies.
The system powers up as many modules as the combined capacity 
allows.

  Power Supply Redundancy
If you power down power supply 1 while power supply 2 is operating, the system will issue a normal 
power supply 1 down indication warning with another warning asking the user not to remove power 
supply 1. If power supply 1 is left in the system, even if it is powered off, the total system power 
will be 4000 W.
If you remove power supply 1 from the system, a major alarm will be issued to warn that the total 
system power will be reduced to 2940 W and that any modules or PoE devices that cause the system 
to exceed 2940 W will power down in 180 seconds (3 minutes). If you insert a replacement power 
supply 1 in the 180-second timeframe, no action will be taken.

  Power Supply Redundancy
NoteIn systems that are equipped with two power supplies, if one power supply fails and the other power 
supply cannot fully power all of the installed modules, system power management will shut down 
devices in the following order: 
Power over Ethernet (PoE) devices— The system will power down PoE devices in descending order, 
starting with the highest numbered port on the module in the highest numbered slot. 
Modules—If additional power savings are needed, the system will power down modules in 
descending order, starting with the highest numbered slot. Slots containing supervisor engines or 
Switch Fabric Modules are bypassed and are not powered down. 
This shut down order is fixed and cannot be changed.
You can change the configuration of the power supplies to redundant or combined at any time. If you 
switch from a redundant to a combined configuration, both power supplies are enabled (even a power 
supply that was disabled because it was of a lower wattage than the other power supply). If you change 
from a combined to a redundant configuration, both power supplies are initially enabled, and if they are 
of the same wattage, they remain enabled. If they are of different wattage, a syslog message displays and 
the lower wattage supply is disabled.
For additional information about the power management feature and individual module power 
consumption, refer to your software configuration guide.

This section provides brief descriptions of the pluggable transceivers that install in Catalyst 6500 series 
modules and supervisor engines. 
The section is divided into these topics:

100-MB Transceivers
100-MB Small Form-Factor Pluggable (SFP) transceivers are currently the only 100-MB transceivers 
that are supported on a Catalyst 6500 series Ethernet switching module. They are supported only on the 
WS-X6148-FE-SFP Ethernet module.
The 100-MB SFP transceiver module is shown in Figure A-1. Ta b l e A - 1 lists the types of 100-MB SFP 
transceivers and their cabling distances. 
NoteThe 100-MB and the 1-GB SFP transceivers share the same form factor, but are not interchangeable.
