Catalyst 4003 Switch Features

The Catalyst 4003 switch (see Figure 1-1) is a three-slot switch designed for high-performance, high-density wiring closet applications.

Figure 1-1 Catalyst 4003 Switch (Front View)

The Catalyst 4003 switch has a Gigabit Ethernet port and a 12-Gbps nonblocking, full-duplex switching fabric that provides connections between the supervisor engine and the switching modules. The Catalyst 4003 switch supports the Supervisor Engine I. The Supervisor Engine I has a 10BASE-T Ethernet management port (RJ-45 connector) and a console port (DCE DB-25 connector).

The Catalyst 4003 chassis has three slots for online-swappable modules. Slot 1 is reserved for the supervisor engine, which provides switching, local and remote management, and switch-status monitoring. Slots 2 and 3 are available for switching modules.

Table 1-1 describes the features of the Catalyst 4003 switch.

Fan Assembly


Note For complete environmental specifications, including airflow requirements, see Appendix A, "Specifications."


The system fan assembly provides cooling air for the internal chassis components. The fan assembly is a tray of fans that you can insert and remove from the chassis while the system is on line. The Catalyst 4003 switch fan assembly has two fans, and the Catalyst 4006 switch has four fans. The fans exhaust air from one side and draw in fresh air on the other side. Catalyst 4003 switch airflow is shown in Figure 1-3. Catalyst 4006 switch airflow is shown in Figure 1-4.


Caution You must install module filler plates on unused switching module slots to ensure proper airflow.

Figure 1-3 Catalyst 4003 Airflow

Figure 1-4 Catalyst 4006 Airflow

If one fan on the tray fails, the other fans continue to run. A sensor on the supervisor engine monitors internal air temperature. If the air temperature exceeds a specified threshold, the environmental monitor displays warning messages. Threshold and status level descriptions are provided in the "Power Supplies" section.

To replace a fan assembly, see Chapter 4, "Removing and Replacing FRUs."


Note For complete power specifications, see Appendix A, "Specifications."


Power Supplies

The Catalyst 4000 series switches can use a 400 W AC-input power supply (see Figure 1-5), a 400 W DC-input power supply (see Figure 1-6), or a 650 W DC-input power supply (see Figure 1-7). The AC-input power supply has a power cord that connects each power supply to the site power source. The DC-input power supplies are equipped with a compression-style input terminal block that is directly connected to the site power wiring.

The power supply does not have a power switch. Power is provided when the power cord and wiring are installed and plugged into an electrical outlet and the unit is fully seated in the system chassis.

Figure 1-5 400 W AC-Input Power Supply

Figure 1-6 400 W DC-Input Power Supply

Figure 1-7 650 W DC-Input Power Supply

Catalyst 4000 series switches support redundant power supplies. Each power supply has an individual power cord and status LEDs. The Catalyst 4003 switch has one standard power supply and an optional redundant power supply. The Catalyst 4006 switch has two standard power supplies and one optional redundant power supply. Two standard power supplies are required to operate a Catalyst 4006 switch. Systems with three power supplies will share the load with each unit providing approximately one-third of the total load.

When power is removed from one power supply on a Catalyst 4003 switch that has two power supplies, the redundant power feature causes the second power supply to produce full power.

When power is removed from one power supply on a Catalyst 4006 switch that has three power supplies, the other two power supplies produce full power. Load sharing returns when all three power supplies are on.

To replace a power supply, see the "Removing and Replacing the Power Supply" section on page 4-2.

Power Supply LEDs

The AC power supply has two front-panel LEDs:

The LED labeled GOOD is green when the power supply is connected and operating normally.

The LED labeled FAIL is red when there is a problem with the power supply.

Power Supply Fan

Each power supply has a built-in fan. Air enters the front of the power supply (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.

Load-Sharing Feature

When you install and power-on a second power supply on a Catalyst 4003 switch, it provides approximately half of the required power to the system. If one power supply fails, the other power supply immediately assumes full power to maintain uninterrupted system operation.

When you install and turn on a third power supply on a Catalyst 4006 switch, it provides approximately one-third of the power required by the system. If one power supply fails, the other two immediately generate full power to maintain uninterrupted system operation.

When you install a redundant power supply, load sharing and fault tolerance are enabled automatically; no additional software configuration is required.

Environmental Monitoring Feature

With the environmental monitoring and reporting feature, you can keep your system running by resolving adverse environmental conditions before loss of operation. The power supply monitors its own internal temperature and voltages. In the event of excessive internal temperature, the power supply shuts down to prevent damage. When the power supply returns to a safe operating temperature, it restarts. If the power supply output voltage is abnormal, the LED labeled OUTPUT FAIL will light. An instance of substantial input overvoltage can shut down the power supply.

The supervisor engine monitors the status of each power supply and provides a status report through the switch software. For more information on how the supervisor engine monitors the power supplies, refer to the Catalyst 4500 Series Module Installation Guide.

External Power Shelf

The Catalyst 4006 external power shelf contains up to three single-phase, AC-DC, 1050 W, -52 V output power supplies, which can provide Power over Ethernet to enabled switching modules when used with the power entry module.
