Power Supply

Aug 09, 2017

SD-WAN appliances are configured with a single power supply. For a SD-WAN 3000 WANOP appliance, you can order a second power supply. 

SD-WAN 4000/5000 WANOP and 5100 SE appliances are configured with dual power supplies but can operate with only one power supply. The second power supply serves as a backup.

For a SD-WAN Standard Edition 410 appliance, a single chassis power switch is supplied.  The device has an external power brick instead of an internal power supply if a desktop form factor is chosen.

The appliances are shipped with a standard power cord that plugs into the appliance’s power supply. The other end of the cord has a NEMA 5-15 plug on the other end for connecting to the power outlet on the rack or in the wall.

For power-supply specifications, see Common Hardware Components, which describes the various hardware components, hardware platforms and includes a table summarizing the hardware specifications.

Note: If you suspect that a power-supply fan is not working, see the description of your platform. On some platforms, what appears to be the fan does not turn, and the actual fan turns only when necessary.

Electrical Safety Precautions for Power Supply Replacement

  • Make sure that the appliance has a direct physical connection to earth ground during normal use. When installing or repairing an appliance, always connect the ground circuit first and disconnect it last.
  • Always unplug any appliance before performing repairs or upgrades.
  • Never touch a power supply when the power cord is plugged in. As long as the power cord is plugged in, line voltages are present in the power supply even if the power switch is turned off.

Replacing an AC Power Supply

A NetScaler SD-WAN 2000 appliance can accommodate only one power supply, which is not field replaceable. A NetScaler 3000 appliance has only one power supply, but you can order and install a second power supply.

Note: Shut down the appliance before replacing the power supply.

To install or replace an AC power supply in a SD-WAN 3000 appliance

  1. If replacing an existing power supply, align the semicircular handle, so that it is perpendicular to the power supply, loosen the thumbscrew, press the lever toward the handle and pull out the existing power supply, as shown in the following figure.

    Note: The illustration in the following figures might not represent the actual SD-WAN appliance.

  3. On the back of the appliance, align the power supply with the power supply slot.

  4. Insert the power supply into the slot and press against the semicircular handle until you hear the power supply snap into place.
