• 32-port 10/100-Mbps Ethernet plus 2-port Gigabit Ethernet uplinks—WS-X4232-GB-RJ—This module

provides 32 ports of dedicated 10/100 Ethernet switching for Ethernet or Fast Ethernet client or server switching,

along with 2 dedicated Gigabit Ethernet connections for Cisco Gigabit EtherChannel connection to a high-speed

core or Gigabit Ethernet server connections. All 10/100 ports can use Cisco Fast EtherChannel technology for

higher-speed uplinks or server connections.

• 32-port 10/100-Mbps Ethernet BASE plus modular uplink support—WS-X4232-RJ-XX—This module provides

32 ports of dedicated 10/100 Ethernet switching for Ethernet or Fast Ethernet client or server switching. Optional

uplink daughter cards provide 4-port 100BASE-FX multimode fiber connections when attached to the 32-port

10/100BASE card. All ports can use a Cisco EtherChannel connection to connect to a high-speed core or Gigabit

Ethernet server. All 10/100 ports can use Cisco Fast EtherChannel technology for higher-speed uplinks or server

connections.

• 4-port 100-Mbps Fast Ethernet uplink module—WS-U4504-FX-MT—This daughter-card option provides

4 ports of dedicated 100 Fast Ethernet (multimode) switching for client or server switching (requires the 32-port

10/100-Mbps Ethernet BASE card).

• 2-port Gigabit Ethernet (GBIC slot)—WS-X4302-GB—This module provides two ports of dedicated

1000BASE-X Gigabit Ethernet uplinks for high-speed backbone switch-to-switch applications or smaller

server-farm applications. It uses versatile GBIC technology, allowing intrabuilding multimode connections to be

intermixed with long-distance campus single-mode connections. All ports can use Cisco Gigabit EtherChannel

technology for high-speed interconnection applications.

• 6-port Gigabit Ethernet (GBIC slot)—WS-X4306-GB—This module provides six ports of dedicated

1000BASE-X Gigabit Ethernet uplinks for high-speed backbone switch-to-switch applications or smaller

server-farm applications. It uses versatile GBIC technology, allowing intrabuilding multimode connections to be

intermixed with long-distance campus single-mode connections. All ports can use Cisco Gigabit EtherChannel

technology for high-speed interconnection applications.

• 18-port Gigabit Ethernet (GBIC slot)—WS-X4418-GB—This module is targeted specifically at building

cost-effective 1000BASE-X Gigabit Ethernet server farms, rather than backbone switch-to-switch applications.

It provides 2 dedicated Gigabit Ethernet uplinks, and up to 16 ports per module for high-performance Gigabit

Ethernet server connectivity. The 16 server ports can burst to Gigabit Ethernet line rate and share 8 Gbps of

full-duplex bandwidth into the switching fabric. Because all ports use GBICs, the amount of oversubscription can

be controlled simply by varying the number of GBICs used. The server ports use the standard IEEE 802.3x

flow-control (pause frame) mechanism to control Gigabit Ethernet host traffic.

• 48-port 1000BASE-LX Gigabit Ethernet module (small form-factor pluggable [SFP])—WS-X4448-GB-LX—

This module is targeted specifically at Ethernet in the First Mile (EFM) opportunities. It can provide up to 240

ports of IEEE 802.3z 1000BASE-LX per Cisco Catalyst 4000 Series switch, allowing service providers to run

point-to-point Gigabit Ethernet fiber links over single-mode fiber within the access/distribution layer of the

network. The module includes 48 1000BASE-LX SFP optics preloaded at the factory.

• 24-port 10/100/1000BASE-T module (RJ-45)—WS-X4424-GB-RJ45—This module, with multispeed

autosensing, autonegotiating technology, provides wiring-closet and server-farm investment protection by

allowing Fast Ethernet desktops and servers to migrate to Gigabit Ethernet in the future without replacing the

switch line cards. All 24 ports can be used at 10 Mbps, 100 Mbps, or 1000 Mbps up to 100 meters over Category

5 copper cabling. The 24 ports can burst to Gigabit Ethernet line rate and share 12 Gbps of full-duplex
