FAQs

Q: When should I choose the 128G RSP over the 400G variant?
A: Select the 128G RSP for lower-throughput aggregation or edge deployments where 128 Gbps of system capacity is sufficient.

Q: Does this RSP support redundant operation?
A: Yes. Two compatible RSPs can be installed for 1+1 redundancy and hitless switchover in supported configurations.

Q: Are timing features included?
A: Yes. SyncE and IEEE 1588v2 are supported to enable precise network synchronization.

Q: Is additional licensing required for advanced features?
A: Some features may require appropriate software licenses; verify your software image and licensing options.
