Classic Gigabit Ethernet over Copper
The Cisco Catalyst 4500 Series offers a variety of gigabit-over-copper solutions for wiring closets
and server farms, enabling high-density gigabit connectivity to the desktop and servers over
Category 5 copper cabling. The line-card options for the Cisco Catalyst 4500 Series (Table 2)
include a 24- and 48-port 10/100/1000BASE-T module in both PoE and non-PoE versions. These
modules provide wiring closet investment protection by allowing Fast Ethernet desktops to migrate
to Gigabit Ethernet in the future without replacement of the switch line cards.
