CHAPTER 3 | Installing the Switch
Connecting to a Power Sourc e
should manually replace the failed link or unit as soon as possible. If you are
using a wrap-around stack t o pol o gy,
a
single
point of failure in the stack will not
cause the stack
to
fail.
It would take two or more points of failure to break the
stack apart.
If the Master unit fails or is powered off, the backup unit will take control of the
stack without any loss of configuration settings. The S lave unit with the lowest
MAC address
is
selected
as the backup unit.
To connect a switch to a power source:
1. Insert the power cable plug directly into the AC socket located at the back of
the switch.
Figure 19: Power Socket
2. Plug the other end of the cable into a grounded, 3-pin, AC power source.
NOTE: For International use, you may need to change the AC line
cord. You must use a line cord set that has been approved for the
socket type in your country.
3. Check the front-panel LEDs as the device is powered on to be sure t he PWR
LED is lit. If not, check that the power cable is correctly plugged in.
