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.

Catalyst 4006 Switch Features
The Catalyst 4006 switch (see Figure 1-2) is a six-slot switch designed for
high-performance, high-density wiring closet applications.
Figure 1-2 Catalyst 4006 Switch (Front View)
The Catalyst 4006 switch has two Gigabit Ethernet ports and a 32-Gbps,
nonblocking, full-duplex switching fabric that provides connections between the
supervisor engine and the switching modules. The Gigabit Ethernet ports can be
configured with any combination of shortwave SX, LX/LH, and ZX GBICs. For
a description of GBICs, refer to the Catalyst 4500 Series Module Installation
Guide.
The Catalyst 4006 chassis has six slots for online-swappable modules. Slot 1 is
reserved for the supervisor engine, which provides switching, local and remote
management, and switch-status monitoring. The Catalyst 4006 switch supports
the Supervisor Engine II, III, or IV. Slots 2 through 6 are available for switching
modules.

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.

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.

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.

Chapter 1 Product Overview
Switch Components
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.

Chapter 1 Product Overview
Switch Components
1-18
Catalyst 4000 Series Switch Installation Guide
78-6120-10
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.
