POWER SUPPLY AND SOURCE RECOVERY MODE
In this mode, two power supply cards are installed and are
connected to two individual power sources. The MX2810 handles
any combination of power source or power supply failure.
Much like the backup design for the controller cards, the MX2810 is
able to internally re-route the power source if a power supply card
and the opposite power source fail. For example, in the illustration
given in Figure 8-3, failed POWER
