Notes on Changing AC Power to DC Power
Infoblox offers the ability to change an AC-equipped Infoblox 4000 Series appliance to use DC power supply units (PSUs) by ordering
field-replaceable unit DC PSUs (listed in
). Should you choose to swap out an appliance's AC power supplies to use DC power supplies,
Table 10
follow these key points:
You cannot convert an AC-equipped Infoblox 4000 Series appliance to NEBS compliance by swapping out AC power supplies for DC
power supplies. You are simply changing the power factor of the appliance.
Ensure that you have proper ground connections that connect to the ground lug screws on each DC PSU. These lug screws will be
marked with a standard electrical ground symbol on each DC PSU, as labeled in
.
Figure 16
Your Infoblox 4000 Series appliance provides a ground lug, with two star washers and a ground lug screw, in the accessory kit bundled
with your appliance. (This accessory is not used for AC power.) Ensure that this ground lug is properly installed with a grounding cable to
chassis ground. For information, see

Ground Lug Installation (DC Systems Only)
Important – Retain your original AC power supplies for possible future RMAs
When you remove the AC power supplies for new DC power supplies, ensure that you keep the original AC power supplies in a safe plac
e for use in RMA situations.
For appliance RMAs, you must replace the DC power supplies in the appliance with its original AC power supplies
RMA shipment
before
back to Infoblox.
Keep your DC power supplies in your facility until you receive your replacement appliance.
Internal System Fan Replacement
System fans are field-replaceable units. Should a CPU fan assembly fail, an alarm will be raised by the system. Infoblox 4000 Series appliances
require no tools for fan replacement.
Note: The Infoblox 4000 Series appliance reports all system fans, numbered 1 through 6, as individual units, and each fan may be individually
replaced as needed. Each fan is numerically labeled inside the chassis.
System fans are hot-swappable; they can be replaced while the system is on. Infoblox recommends that the system be switched off before
replacing a fan unit. To replace a fan assembly, do the following:
Perform a full system shutdown.
Unplug all power cables from the system.
Note: Steps #1 and #2 are optional.
3. Extend or remove the Infoblox appliance from the rack.
