Establishing Power Fault-Tolerance
Operate the switch in power fault-tolerant mode to ensure that at least one supply's worth of power is
available to replace power lost when and if a single power supply fails.
To set the switch to power fault-tolerant mode or power non-fault-tolerant mode enter the SET POWER
MODE command at the terminal prompt.
When you attempt to set the switch to power fault-tolerant mode, the active controller module determines if
there is sufficient unallocated power budget available to place one power supply's worth of power in
reserve.
If there is sufficient unallocated power budget, the switch sets to power fault-tolerant mode.
If there is insufficient unallocated power budget, the switch remains in power non-fault-tolerant mode.
CAUTION:
The 8265 may reset unpredictably when in power fault-tolerant mode if there is insufficient power
in reserve when a power supply failure occurs.
Displaying Current Power Mode
To display which of two power modes is currently in effect (power fault-tolerant mode or power
non-fault-tolerant mode), use the following command syntax:
SHOW POWER MODE
When you enter SHOW POWER MODE command while the 8265 is running in power non-fault-tolerant
mode, the following information is displayed:
