FAQs

Q: Is this PSU hot-swappable?
A: No. Power down the router before replacing the supply.

Q: Does this add PoE to my router?
A: No. PoE requires the appropriate PoE hardware option for your router model; this PSU alone does not provide PoE.

Q: How can I confirm compatibility?
A: Verify your router model is 2921 or 2951 and match the power supply form factor to the original unit.

Q: Do I need any licenses after replacing the PSU?
A: No licenses are required for a power supply replacement.

Q: Is a power cord included?
A: This is the internal PSU module; reuse your existing chassis power cord.
