Power Supply Recovery Mode; Figure 8-2. Power Supply Failure Recovery Mode - ADTRAN MX2800 User Manual

POWER SUPPLY RECOVERY MODE

In Power Supply Recovery Mode, two power supply cards are
installed and connected to a single power source (see Figure 8-2).
In this mode, the MX2800 can continue operation in the event of a
power supply failure, without interrupting service. The power
supplies are load sharing, so either power supply can provide
power for the entire unit.
When the unit is configured with dual internal AC power supplies, then
this is the only power protection mode available.
