FAQs

Q: Which chassis are compatible with this RSP?
A: It is designed for use in NCS 4200 family chassis, including 6-slot and 16-slot models, subject to specific hardware/software compatibility.

Q: Can I deploy two RSPs for redundancy?
A: Yes. Installing two compatible RSPs enables 1+1 control-plane redundancy for hitless switchover in supported configurations.

Q: What is the difference between the 400G and 128G RSP variants?
A: The 400G variant provides higher system switching capacity and scale compared to the 128G model; both share similar software feature sets, subject to licensing.

Q: Are software features license-activated?
A: Yes. Certain advanced features may require appropriate software licenses; consult your software image and licensing guide.
