damage by running it through wall, floor, or roof
cavities. In the event of damage to patch cables or damage to

3.6 Implementing Physical Layer
Solutions 3.6.6 Solving common problems –
support resources Online resources represent an invaluable
tool for the network troubleshooter. The Internet has become a
very valuable corporate tool for those seeking answers on
specific technical problems. It also potentially represents a
vast pool of experience-based information. The Cisco systems
web site reached at http://www.cisco.com/ incorporates customer
support, press-release information and a free knowledge base
tool on all things Cisco. This site represents an invaluable
resource for Cisco customers, support staff and for network
administration, troubleshooting and design personnel in
general. It contains troubleshooting, implementation and the
original white papers on all aspects of data networking
technology. Other highly useful resource sites are as follows:
- Microsoft website: http://www.microsoft.com
- Apple website: http://www.apple.com
- Sun website:
http://www.sun.com
- Linux website:
http://www.linux.org
