Redundancy

Catalyst 6500 series switches have these redundancy features:


Note    In certain configurations, the power supplies are not fully redundant. Refer to the "Power Supply Redundancy" section.

Component Hot Swapping

You can hot swap all modules (including the supervisor engine if you have a redundant supervisor engine) and the fan assembly. You can add, replace, or remove modules without interrupting the system power or causing other software or interfaces to shut down.

Fan Assembly

The system fan assembly is located in the chassis and provides cooling air for the supervisor engine and the switching modules. The following figures show the direction of airflow into and out of the switch:

Sensors on the supervisor engine monitor the internal air temperatures. If the air temperature exceeds a preset threshold, the environmental monitor displays warning messages.


Note   We recommend that you maintain a minimum air space of 6 inches (15 cm) between walls and the chassis air vents and a minimum horizontal separation of 12 inches (30.5 cm) between two chassis to prevent overheating.

If an individual fan within the assembly fails, the FAN STATUS LED turns red. Individual fans cannot be replaced. To replace a fan assembly, see the "Removing and Replacing the Fan Assembly" section.

Refer to your software configuration guide for information on environmental monitoring.

Power Supplies

Catalyst 6500 series switch power supplies are available in five power ratings:

950 W Power Supply (PWR-950-AC and PWR-950-DC)


Note   The 950 W AC-input and DC-input power supplies can be installed in the Catalyst 6503 switch chassis only. They cannot be installed in any other Catalyst 6500 series switch chassis.

The 950 W power supplies (see Figure 1-14) do not connect directly to source AC but use a power entry module (PEM), located on the front of the chassis, to connect the site power source to the power supply located in the back of the chassis.

The AC-input PEM (shown in Figure 1-15) and DC-input PEM (shown in Figure 1-16) provide an input power connection on the front of the router chassis to connect the site power source to the power supply. You can connect the DC-input power supply to the power source with heavy gauge wiring connected to a terminal block. The wire gauge size is determined by local electrical codes and restrictions.


Note   The power cord is not shown in Figure 1-15.

The PEMs have an illuminated power switch (AC-input only), current protection, surge and EMI suppression, and filtering functions.

1000 W, 1300 W, 2500 W, and 4000 W Power Supplies

The 1000 W, 1300 W, 2500 W, and 4000 W AC-input and DC-input power supplies have the same form factor and designed for use in the Catalyst 6500 series switches.


Note   The 1000 W, 1300 W, 2500 W, and 4000 W power supplies have a different form factor and cannot be used in the Catalyst 6503 series switch.

Catalyst 6500 series switch chassis power supply configurations for the 1000 W, 1300 W, 2500 W and 4000 W power supplies are shown in Table 1-8.

Catalyst 6500 series switches support redundant AC-input and DC-input power supplies. Unlike the Catalyst 4000 family and Catalyst 5000 family switches, the Catalyst 6500 series switches allow you to mix AC-input and DC-input power supplies in the same chassis.

Many telco organizations require a -48 VDC power supply to accommodate their power distribution systems. From an operational perspective, the DC-input power supply has the same characteristics as the AC-input version.

The AC-input power supply (see Figure 1-17) has a detachable power cord (except for the WS-CAC-4000W) that allows you to connect each power supply to the site power source. You can connect the DC-input power supply (see Figure 1-18) to the power source with heavy gauge wiring connected to a terminal block. The wire gauge size is determined by local electrical codes and restrictions.


Note   The power cord is not shown in Figure 1-17.


Note   With a fully populated Catalyst 6513 switch, two 2500 W power supplies are not fully redundant. If you run the 2500 W power supply at the low range input (100 to 120 VAC), it is not redundant in a fully populated Catalyst 6509, Catalyst 6509-NEB, or Catalyst 6509-NEB-A switch.


Note   The 2500 W AC-input power supply needs 220 VAC to deliver 2500 W of power. When powered with 110 VAC, it delivers only 1300 W. In addition, the power supply needs 16 A, regardless of whether it is plugged into 110 VAC or 220 VAC.

For complete power specifications, see "Technical Specifications."


Figure 1-17   AC-Input Power Supply



Figure 1-18   DC-Input Power Supply


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. Although the power management feature allows you to power all installed modules with two power supplies, redundancy is not supported in this configuration. Redundant and nonredundant power configurations are summarized in Table 1-9. The effects of changing the power supply configurations are summarized in Table 1-10.


Note   For 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.

Table 1-9   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 come online, but a syslog message displays that the lower wattage power supply will be disabled. If the active power supply fails, the system shuts down. The lower wattage power supply must then be manually turned on. The lower wattage power supply selectively powers up the modules so that the capacity of the power supply is not exceeded.

Equal or unequal wattage

Disabled

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, thus preventing damage to the lower wattage power supply.

Table 1-10   Effects of Power Supply Configuration Changes

Configuration Change  Effect 

Redundant to nonredundant

  • System log and syslog messages are generated.
  • System power is increased to approximately 167 percent of the lower wattage power supply.
  • The modules marked as power-deny in the show module Status field are brought up if there is sufficient power.

Nonredundant to redundant

  • System log and syslog messages are generated.
  • System power is the power capability of the larger wattage 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.

Equal wattage power supply is inserted with redundancy enabled

  • System log and syslog messages are generated.
  • System power equals the power capability of one supply (both supplies provide approximately one half of the total current).
  • No change in the module status because the power capability is unchanged.

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.

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.

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 manually turned on. (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.
  • The lower wattage supply is disabled.

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.

You can change the configuration of the power supplies to redundant or nonredundant at any time. If you switch from a redundant to a nonredundant 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 nonredundant to a redundant configuration, both power supplies are initially enabled, and if they are of the same wattage, 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.

Environmental Monitoring of the Power Supply

The environmental monitoring and reporting functions allow you to maintain normal system operation by resolving adverse environmental conditions prior to loss of operation.

The power supplies monitor their own internal temperature and voltages. In the event of excessive internal temperature, the power supply will shut down to prevent damage. When the power supply returns to a safe operating temperature, it will restart. In the event of an abnormal voltage on one or more outputs of the power supplies, the OUTPUT FAIL LED will light. Substantial overvoltage conditions can lead to a power supply shutdown.

The power supply front panel LEDs are described in Table 1-11.

For more information about the environmental monitoring feature, refer to your software configuration guide.

Table 1-11   Power Supply Front Panel LEDs

LED  Description 

INPUT OK

AC-input power supplies:

  • Green when the input voltage is OK (85 VAC or greater)
  • Off when the input voltage falls below 70 VAC or if the power supply shuts down

DC-input power supplies:

  • Green when the input voltage is OK (-40.5 VDC or greater)
  • Off when the input voltage falls below -33 VDC or if the power supply shuts down

FAN OK

Green when the power supply fan is operating properly. Red when a power supply fan failure is detected.

OUTPUT FAIL

Red when there is a problem with one or more of the DC-output voltages of the power supply.

Power Supply Fan Assembly

The power supplies have a built-in fan; air enters the front of the fan (power-input end) and exits through the back. An air dam keeps the airflow separate from the rest of the chassis, which is cooled by the system fan assembly.

Power supply fans are not field-replaceable; the power supply must be replaced. To replace a power supply, see the "Removing and Installing the AC-Input Power Supplies" section or "Removing and Installing DC-Input Power Supplies" section.
