Unpacking a Power
Supply
The Switch 4005 can hold two power supplies. Only one power supply is
required for operation. If installed, a second power supply provides
complete redundancy if the other power supply fails.
If the power source to the Switch 4005 fails, the power supplies in the
switch do not function as battery backups.
All Switch 4005 chassis ship from the manufacturing center with one
power supply preinstalled. However, you can purchase a second power
supply separately and install it at your site.
This section contains instructions and cautions to be aware of when
unpacking an individual power supply (Model Number 3C16822).
1 Before you continue to unpack the shipping box, carefully examine it for
signs of damage.
If the shipping box shows any signs of damage, replace any items that
you have already removed, reseal the shipping box, and contact your
network supplier (the company from which you purchased the product)
immediately.
If you cannot contact your supplier, contact 3Com Customer Service:
■ If you are located in the United States or Canada, call
1-800-NET-3COM (1-800-638-3266) and select the numeric option to
reach customer service and the product repair departments.
■ If you are located in another country, find the appropriate telephone
number from the 3Com Web site:

2 Remove the protective wrap and inspect the power supply for damage. If
damage exists, follow the instructions in step 1.
3 Replace the protective wrap and return the power supply to its shipping
box until you are ready to install it.
4 Read the Switch 4005 Installation and Maintenance Guide for important
safety information and instructions for removing and installing power
supplies.
A printed copy of this guide is included in all chassis shipping boxes.
