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 third-
party 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.

Setup
Network Wiring
When wiring the Ethernet network, use Category 5 (CAT5) wiring.
CAT5 wiring is a twisted pair cable designed for Ethernet networks.
These networks operate at speeds of up to 100 Megabits per second
(Mbps) using the 100BaseT standard.
For information on connecting Ethernet devices in a Crestron system,
refer to the latest version of the Crestron e-Control®Reference Guide
(Doc. 6052), which is available for download from the Crestron website
