WARNING: The Switch 4005 chassis and its components (such as fan trays) must
be installed, maintained, or replaced only by trained service personnel. This guide
assumes that the network administrator has a working knowledge of local area
network (LAN) operations. Furthermore, this guide assumes that the network
administrator has obtained appropriate technical training and experience to
perform tasks in service access areas of network equipment, to be aware of
electrical hazards that exist in performing these tasks, and to take steps that
minimize the danger to themselves or other persons. If you have questions on
installation tasks, contact your network supplier or 3Com technical support. See
Appendix A for contact information.
