7. Connect the Switch to a Power Source
1. Plug the included power cord into the switch’s power connector and into
a nearby properly grounded AC power source.
If a redundant power source is available, it is desirable to power one
switch power supply from the regular AC source, and the other power
supply from the independent AC source. This will provide redundancy in
AC power to the switch, as long as the switch PoE power usage falls within
the capability of one power supply. If both power supplies are plugged
into a common AC source, there is still power supply redundancy, that is,
protection against power supply failure, but if the AC source fails, the
switch will lose all power.
2. Re-check the LEDs during self test. See “LED Behavior” on page 2-16 .
