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.

Feature Description
Ethernet speeds
• Ethernet (10BASE-T) interface to workstations and repeaters
• Fast Ethernet (100BASE-T) interface to workstations, servers, switches,
and routers
Note Autonegotiation of link speed on each 10/100 port allows migration
to 100BASE-T from a 10BASE-T installed base.
Standard equipment
• Three-slot modular chassis with one slot reserved for a supervisor
engine and two slots for switching modules
• Two power supply bays that support one required and one optional
redundant AC-input power supply
• One hot-swappable fan assembly
Standard management
and support
• Layer 2 forwarding with an aggregate forwarding rate of greater than
17.8 million pps
• 16,000 MAC addresses per system
• Up to 1,024 VLANs with IEEE 802.1Q VLAN tagging on all ports and
support for VTP
1
• Port aggregation using PAgP
2
for 100-Mbps and 1000-Mbps
EtherChannel
Software management
• CLI
3
and SNMP interfaces consistent with the Catalyst 6500 series
switches
• Out-of-band management (SNMP, Telnet client, and TFTP) through the
10BASE-T management port on the supervisor engine
• RMON
4
with RMON 1
• Standard Layer 2 features:
–
802.1D Spanning Tree Protocol
–
CDP

Embedded management • Full SNMP implementation, including entity-MIB, all relevant standard
MIBs, and all relevant Cisco MIBs
• The first four RMON groups (Ethernet statistics, Alarms, Events, and
History supported) on a per-port basis without an optional RMON
processing module
• SPAN, allowing redirection of traffic from any port or VLAN to a SPAN
destination port
• Performance management information
Power supplies
• One standard 400 W, 12 V output, hot-swappable, load-sharing
redundant power supplies with AC power factor correction
• Optional 400 W, 12 V output DC power supplies
• Optional 650 W, 12 V output DC power supplies
• PoE is not supported on the Catalyst 4003
Supervisor engine
• Supports the Supervisor Engine I (WS-X4012)
• Data path and control for all network interfaces with Ethernet
management and console ports
• Interface monitoring, environmental status, and SNMP and
console/Telnet interface
Note Packets are not forwarded while the supervisor engine is removed; a
system reboot occurs when a supervisor engine is reinserted.
• Gigabit Ethernet (1000BASE-X) interface for backbone interconnection
of high-performance switches and routers
