About the Switch
4400
The Switch 4400 is a stackable 10/100 Mbps Ethernet switch and
provides high-performance work groups with a backbone to server
connection. The Switch 4400 allows Cascade, Gigabit Ethernet or Fast
Ethernet Fiber connections when expansion modules are installed in the
expansion slots on the rear of the unit. You can also add the Switch 4400
to any SuperStack
® system as your network grows.
The Switch 4400 PWR (3C17205) supports Power over Ethernet (PoE) on
all front panel ports. If you plug in a compatible (IEEE 802.3af compliant)
device, it will be automatically detected and power supplied to it. PoE is
enabled on each port by default.
