To install a new fan tray in the Switch 4005 chassis, follow these steps:
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.
Before you begin, have ready a flathead screwdriver.
1 Facing the back of the chassis, grasp the front panel of the fan tray around the
edges.
2 Slide the fan tray into the chassis, using the guides in the chassis slot.

3 Gently push the fan tray inward until the connectors engage.
You will feel a slight resistance as the connectors engage.
CAUTION: If the resistance is too great, the fan tray connector and chassis
connector may not be aligned properly. Do not force the fan tray inward or you
can damage the connectors. If necessary, remove and reinsert the fan tray.
