Overview
Note Each fan module has two rotors. The switch can function normally if one rotor
inside the any one fan module fails. In case of more than one rotor failure, the
switch will issue a warning and power down in 2 minute.
Note
This switch runs with +1 redundancy mode, so that if one fan fails, the switch
can sustain operation. But if a 2nd fan fails, this switch is not designed to sustain
operation. Hence before waiting for major threshold temperature to be hit, the
switch will power down due to Powered-down due to fan policy trigger.
• Power supply modules (two—One for operations and one for redundancy [1+1]) with the following
choices:
• 715-W port-side intake DC power supply with blue coloring (NXA-PDC-715W-PI)
• 1100-W port-side exhaust AC power supply with blue coloring (NXA-PAC-1100W-PE)
• 1100-W port-side intake AC power supply with burgundy coloring (NXA-PAC-1100W-PI)
• 1900-W port-side intake AC power supply with burgundy coloring (NXA-PAC-1900W-PI)
Note The NXA-PDC-715W-PI power supply is only supported from Release 6.0.4 and
later.
Additional limitations when using the NXA-PDC-715W-PI power supply include
the following:
Note
All fan modules and power supplies must use the same airflow direction.
Note
The details of the 1900-W power supply (NXA-PAC-1900W-PI) will not display
in the CLI show commands, until a working power source is connected to the
power supply.
