Power Supply Module (Labeled 1 and 2)

The Mediant 1000 features two extractable power supply units, Power 1 and Power 2 (refer
to Figure 2-2
2-6 on page 31).
If both Power 1 and Power 2 units are used, they share the load between them. This
(optional) load-sharing feature enables failure protection / redundancy. When using this
feature, users are advised to connect each power supply unit to a different AC supply
circuit.
If a user chooses either a hardware configuration option involving only one power supply
unit, or two units but chooses to cable only one, failure protection / redundancy cannot
occur.
