Figure 6   Fitting a bracket for rack-mounting
You must use the screws supplied with the securing brackets. Damage 
caused to the unit by using incorrect screws invalidates your warranty.
Repeat steps 2 and 3 for the other side of the Switch.
Insert the Switch into the 19-inch rack and secure with suitable screws 
(not provided). Ensure that ventilation holes are not obstructed.
Connect network cabling.
Placing Units On 
Top of Each Other
If the Switch units are free-standing, up to four units can be placed one 
on top of the other. If you are mixing a variety of Switch and Hub units, 
the smaller units must be positioned at the top.
If you are placing Switch units one on top of the other, you must use the 
self-adhesive rubber pads supplied. Apply the pads to the underside of 
each Switch, sticking one in the marked area at each corner. Place the 
Switch units on top of each other.
