5.9 Connecting to Power
The supported power type depends on the Mediant 800 hardware revision:
Mediant 800B: Only AC power
Mediant 800C: AC and DC redundant power. When both power supplies are used (AC
and DC), the device is powered from the AC power source only. The DC source starts
feeding the device only upon an AC power outage.
Notes: For Mediant 800C, the device is always shipped with AC power support. DC
power is also available if the device is ordered with DC support (AC/DC power adaptor
is provided).
5.9.1 Connecting to AC Power
The device receives power from a standard alternating current (AC) electrical outlet. The
connection is made through the supplied AC power cord.
