Power Considerations
This section describes the power considerations for the router, the service module, and stacking the
service modules:
Power Considerations for the Router
Power Considerations for the Service Module
Powering Considerations for a Switch Stack
Warning
Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if
interconnections are made using uninsulated exposed metal contacts, conductors, or terminals.
Avoid using such interconnection methods, unless the exposed metal parts are located within a
restricted access location and users and service people who are authorized within the restricted
access location are made aware of the hazard. A restricted access area can be accessed only through
the use of a special tool, lock and key or other means of security.
Statement 1072
Power Considerations for the Router
Cisco 2800 series, Cisco 3700 series, and Cisco 3800 series routers supply –48 V power internally (with
AC-IP power supplies) to the Cisco EtherSwitch service modules.
Note that the Cisco 3700 routers are not 802.3af-compliant, and the Cisco 2691 routers do not provide
PoE.
