Cisco Cisco Content Delivery Engine 100 Guida All'Installazione

This chapter contains site requirements and important safety information you should know before 
working with the Cisco Content Delivery Engines (CDEs). Use the guidelines in this chapter to ensure 
your own personal safety and to help protect your CDE from potential damage.

Read the Regulatory Compliance and Safety Information for the Cisco Content Delivery Engines 
document that came with your CDE before you begin the installation.

This section provides site requirements for the CDEs. You should verify the site power prior to installing 
the CDEs. 

The CDEs have no user-serviceable parts inside their chassis. The only field-replaceable units are the 
AC and DC power supplies and storage drives. 

Electrostatic discharge (ESD) damage, which can occur when drives, electronic cards, or components 
are improperly handled, results in complete or intermittent failures. Follow these advisories to prevent 
damage from ESD: 

Always use an ESD wrist or ankle strap and ensure that it makes good skin contact. 

Connect the equipment end of the strap to a bare metal, unpainted chassis surface. 

When removing or installing a component, use any available handles, ejector levers, or captive 
installation screws. These devices prevent accidental removal, provide proper grounding for the 
system, and help to ensure that bus connectors are properly seated.
