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 STS-1 can continue to operate during a
power supply failure, without interrupting service. The power
supplies are load sharing, so either power supply can provide power
for the entire unit.
Figure 8-2. Power Supply Failure Recovery Mode
When the unit is configured with dual internal AC power supplies,
this is the only power protection mode available.
