SET POWER MODE
2-201
SET POWER MODE
Use the SET POWER MODE command to choose between normal and
fault-tolerant power supply operation using the CoreBuilder 5000 hub intelligent
power management system.
For example:
■
Each power supply provides approximately 200 watts at +5 Volts
■
You have three power supplies available (approximately 600 watts)
In this scenario, non-fault tolerant mode allows you to use approximately 600
watts. Fault-tolerant mode allows you to use approximately 400 watts, reserving
approximately 200 watts to use in the event of a failure.
Regardless of the power mode setting, the power load being used is shared
across all installed power supplies.
Refer to documentation for your power supply to determine the power supply’s
maximum power output.
Format
Example
The following command attempts to set the CoreBuilder 5000 hub power mode
to fault tolerant:
CB5000> set power mode fault_tolerant
Power will switch to FAULT-TOLERANT mode when sufficient power is
available.
The command fails because the installed power is insufficient to support
fault-tolerant mode. Fault-tolerant mode automatically enables when sufficient
power becomes available (when you add another power supply).
Related Command
SHOW POWER
fault_tolerant
Power Management calculations hold a power supply’s worth of
power in reserve, so that there is still enough power available if a
power supply fails. To use fault-tolerant mode, you must have one
more power supply than is required to power all modules in the hub.
non_fault_tolerant
Power Management calculations use the entire capacity of all installed
power supplies when calculating available power. To use normal
mode, you must have enough power supplies to power all modules in
the hub.
