Installing the Extended Chassis 3-3
When installing your Extended chassis on a tabletop, make sure there is
adequate space on the right side and back of the unit for ventilation.
Figure 3-2 Installing an Extended Chassis on a Tabletop
Installing in a Rack
Your Extended chassis comes with a rack-mount kit which consists of two
brackets, 14 pan-head screws, and eight locking nuts. This kit allows you to
mount the chassis in a 19-inch, 2- or 4-pole rack. Make sure the kit contains all
of these parts. If a part is missing, contact your network supplier.
You will need a Phillips screwdriver to mount the chassis in the rack. Because of
the weight of the Extended chassis, you will need at least two people to
complete the procedure. The unit will be more secure if installed toward the
bottom of the rack.
Using fewer than four screws on each side of the Extended chassis to secure
the brackets to the rack may result in bracket failure and damage that will
invalidate the warranty.
