Crestron CEN-SW-POE-5 5-Port Power over Ethernet Switch
5-Port Power over Ethernet
Switch: CEN-SW-POE-5
Introduction
The CEN-SW-POE-5 is a five-port unmanaged Ethernet switch designed
to provide standards-based IEEE 802.3af Power over Ethernet (PoE)
capability from four ports. The CEN-SW-POE-5 powers Crestron
802.3af-compliant powered devices such as the CEN-WAP-ABG-1G
wireless access point. In addition, the CEN-SW-POE-5 can power thirdparty 802.3af-compliant powered devices. Using the CEN-SW-POE-5,
a separate power supply is not needed at the location of each
powered device.
The CEN-SW-POE-5 also provides an uplink port that connects to a
network hub or switch.
NOTE: The uplink port does not provide PoE capability.

5-Port Power over Ethernet Switch Crestron CEN-SW-POE-5
Features and Functions
• Four 10BaseT/100BaseTX 802.3af PoE ports
• One 10BaseT/100BaseTX uplink port
• Autonegotiation of data transmission rate and duplex mode
• Auto MDI/MDI-X (Medium Dependent Interface/Medium
Dependent Interface Crossover) operation
• 3.2 Gbps switching fabric
• Wall and rack mountable design
Four 10BaseT/100BaseTX 802.3af PoE Ports
Using 802.3af PoE technology, each of four 10BaseT/100BaseTX ports
can provide power to an 802.3af-compliant Ethernet device using the
same cable as that used for the network connection. In addition, PoE
technology provides built-in protection to prevent damage from occurring
when power is applied to non-PoE devices.
Auto MDI/MDI-X Operation
A straight-through or crossover cable can be used to connect to any port
on the CEN-SW-POE-5. Using auto MDI/MDI-X operation, the port
automatically detects the cable type that is used.
