14 CHAPTER 1: UNPACKING INSTRUCTIONS
Unpacking a
Fan Tray
The Switch 4005 chassis houses two fan trays. Each fan tray contains two
fans. All four fans are required for normal operation.
All Switch 4005 chassis and starter kits ship from the manufacturing
center with two fan trays preinstalled. You do not have to order or install
a fan tray in a Switch 4005 chassis unless one or both fans in a fan tray
fail.
This section contains instructions and cautions when unpacking an
individual fan tray (order number 3C16823).
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 fan tray supply for damage.
If damage exists, follow the instructions in step 1.
3 Replace the protective wrap and return the fan tray 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 fan trays.
A printed copy of this guide is included in all chassis shipping boxes.
