with a transformer. This allows customers to use existing Category 5 UTP installations. The Cisco EtherSwitch Network
Module in-line power implementation passes the required U.S. and international safety regulations and compliance
measures.
• NM-16ESW-PWR—The 16-port Ethernet switch network module with power daughter card supports in-line powering
of IP telephones with –48V power when purchased with the external power chassis. This allows IP phones to be plugged
into any port. Also, the integrated in-line power of the 10/100BaseTX autosensing ports provides DC power to devices
that can accept power over traditional UTP cabling (such as the Cisco 7900 Family of IP phones). This allows a standard
RJ-45 jack to be powered from this source rather than having a separate plug into an AC wall outlet. Delivery of –48V
power must be made to the 16-port Ethernet switch.
• PPWR-PS-360W—This single 360W power supply for the Cisco EtherSwitch Network Module line power can be added
to a power chassis to power additional IP phones or wireless access points. Each power supply supplies up to 360W and
can power up to 36 IP phones.

Small Branch Data Only
A Cisco EtherSwitch Network Module in a branch data deployment provides the flexibility of integrated routing and
switching functions in one unit for low port densities. This deployment provides high-speed connections between individual
desktops, servers, and other network resources in a single unit for Layer 2 and allows WAN connection at Layer 3 through
the router. The Cisco EtherSwitch NM and Cisco 2600router also provide an ideal solution for Cisco 2505, 2507, and 2516
users whose requirements have expanded beyond the existing Cisco 2500 Router/hub capabilities.
