Chapter 18 Connecting Cisco EtherSwitch Service Modules Power Considerations In addition, the last two port LEDs on the Cisco StackWise EtherSwitch service module show the status of the StackWise ports.

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. OL-2485-20 Cisco Network Modules Hardware Installation Guide 18-13
