The chassis has a front-to-rear airflow. Six internal fans draw cooling air in through the front of the chassis
and across internal components to maintain an acceptable operating temperature. The fans are located at the
rear of the chassis. The fans are numbered from 0 to 5, right to left.
The power supplies used in the controllers are different and they should not be mixed or swapped. The size
and structural dimensions are the same, therefore they both look alike. It would be hazardous, if you accidentally
inserted the wrong power supply into the PEM slot.

Cisco Product Identification Standard
This section describes the Cisco products and services product identification standard. This feature provides
you with the ability to effectively integrate and manage Cisco products in your network and business operations.
Unique Device Identifier
The Unique Device Identifier (UDI) is the Cisco product identification standard for hardware products. A
product identification standard removes barriers to enterprise automation and can help you reduce operating
expenses.
The UDI provides a consistent electronic, physical, and associated business-to-business information product
identification standard.
The UDI is a combination of five data elements. The following table lists the UDI elements.
