Mounting the Switch in a Standard 19" Rack
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.
Figure 2 - 3. Installing Switch in a rack
Power on AC Power
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.
After the Switch is powered on, the LED indicators will momentarily blink. This blinking of the LED indicators represents a reset
of the system.
Power Failure
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.
