Figure 5 WX4400 Installation—Center-Mount Equipment Rack
First, attach brackets to chassis.
Then, install chassis into rack.
1 Remove the four bracket screws from each side of the WX switch.
2 Align a bracket over the screw holes:
For a front-mount equipment rack, align the bracket so that the
bracket flange is flush with the WX switch's front panel and extends
away from the switch.
For a center-mount equipment rack, align the bracket so that the
bracket flange is located near the center screw holes.
3 Reinsert the screws to secure the brackets to the WX switch.
4 Repeat for the other bracket.
WARNING: 3Com recommends that you ask someone to assist you with
the remaining steps. If you accidentally drop the WX switch, you can be
injured and the switch can be damaged.
