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.
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
• Power supply modules (two—One for operations and one for redundancy [1+1]) with the following
choices:
• 650-W port-side exhaust AC power supply with blue coloring (NXA-PAC-650W-PE)
• 650-W port-side intake AC power supply with burgundy coloring (NXA-PAC-650W-PI)
• 1200-W HVAC/HVDC power supply with dual-direction airflow white coloring (N9K-PUV-1200W)
• 930-W port-side exhaust DC power supply with blue coloring (NXA-PDC-930W-PE)
• 930-W port-side intake DC power supply with burgundy coloring (NXA-PDC-930W-PI)
All fan modules and power supplies must use the same airflow direction.
Note
This switch may present access issues if installed between switches with greater
chassis depth. Please consider this before installation.

Deployment Scheme for SFP-10G-T-X Transceivers
The following figure shows the maximum configuration density of SFP-10G-T-X SFP+ transceivers for this
switch.
Active Port deploying the SFP+ 10GBASE-T transceiver, with max power consumption up to
2.5W.
Once configured with “media-type 10g-tx” in NX-OS or “Link Level Policy -> Physical Media
Type -> SFP 10G TX” in ACI, these ports can deploy SFP-10G-T-X. Without such
configuration, they behave like normal ports.
