4000 Series Switches
The 4000 Series is a step up from the 3500, offering a modular configuration in
four different switches: the 4003, 4006, 4840G, and 4908G.The 4000 Series also
offers supervisor engine functionality, similar to that of the 5500 Series.Within
the 4000 Series, the 4006 is currently the only switch to offer inline power; by
use of the Catalyst 4000 inline power 10/100BaseT switching module or the use
of an auxiliary power shelf, the 4006 supports up to 240 10/100 ports.The 4003
is also an Ethernet switch, very similar to the 4006, but unfortunately the 4003
cannot offer inline power functionality.The 4840G and 4908G are both gigabit
Ethernet switches.The 4000 Series also offers voice-gateway functionality
through the use of the Series 4000 WS-X4604-GWY module, which provides
support for both H.323 and SSP (in the future it will support MGCP).
