The Infoblox 4005 Series appliances provide for several replaceable units in the system:

- Hard disk drives
- Fan modules
- AC power supplies
- DC power supplies (if applicable)
- SFP/SFP+ Transceivers

All replaceable units must be replaced with parts of the same specifications as described in this section. For parts and replacements, contact your Infoblox field representative or *Infoblox Technical Support*. You can also order some parts as local spares.
