disconnect all cables from the switch before continuing. remove all self adhesive pads from the underside of the switch if they have been fitted.
to rack-mount your switch:
1 place the switch the right way up on a hard flat surface, with the front facing towards you.
2 locate a mounting bracket over the mounting holes on one side of the switch, as shown in figure 4.
3 insert the two screws and tighten with a suitable screwdriver.
you must use the screws supplied with the mounting brackets. damage caused to the unit by using incorrect screws invalidates your warranty.
4 repeat steps 2 and 3 for the other side of the switch.
5 insert the switch into the 19-inch rack and secure with suitable screws (not provided). ensure that ventilation holes are not obstructed.
6 connect network cabling.
7 finally place a unit information label on the unit in an easily accessible position. the unit information label shows the following:
the 3com product name of the switch
the 3com 3c number of the switch
the unique mac address (ethernet address) of the switch
the serial number of the switch
you may need this information for fault reporting purposes.
