Rack-moun ting 21 If the Switch is installed in a 19-inch rack or closed assembly its local air temperature may be gre ater than room ambient tempe rature. ■ The air is as free fr om dust as possible. ■ The switch is situated away from sources of conductive (electrical) dust, for example, laser printers.
22 C HAPTER 2: I NSTALLING THE S WITCH Figure 5 Fitting a bracket for rack-mounting 3 Insert the two screws and tighten with a suitable screwdriver . Y ou must use the screws supplied with the mounting brackets. Damage caused to the unit by using incorrect screws invalidates your warranty .
Placing Units On Top of Each Other 23 Placing Units On T op of Each Other If the Switch units ar e fr ee-standing, up to eight units can be placed one on top of the other . If you are mixing a variety of SuperStack ® 3 Switch and Hub units, the smaller units must be positioned at the top.
24 C HAPTER 2: I NSTALLING THE S WITCH Stack renumbering occurs when another Switch 4200 Family unit is added to the bottom of an established stack except when the stack is already 4 units high. In this instance the ‘down’ port on the bottom unit of the existing stack will be disabled and its LED will flash green.
