Mounting the Switch in a Standard 19" Rack
Figure 2- 3. Installing the Switch in a rack
Power On (AC Power)
1. Plug one end of the AC power cord into the power connector of the Switch and the other end into the local
power source outlet.
2. After powering on the Switch, the LED indicators will momentarily blink green. This blinking of the LED
indicators represents a reset of the system.
Power Failure (AC Power)
For AC power supply units, as a precaution, in the event of a power failure, unplug the Switch. When power has
resumed, plug the Switch back in.
CAUTION:
Installing systems in a rack without the front and side stabilizers installed could cause the
rack to tip over, potentially resulting in bodily injury under certain circumstances. Therefore, always
install the stabilizers before installing components in the rack. After installing components in a rack, do
not pull more than one component out of the rack on its slide assemblies at one time. The weight of
more than one extended component could cause the rack to tip over and may result in injury.
