FAQs

Q: Can the RJ45 and SFP be used at the same time?
A: No. It is a dual-mode combo port—only one interface (RJ45 or SFP) can be active at a time.

Q: Are SFP transceivers included?
A: No. SFP optics are sold separately.

Q: Which routers support this module?
A: It is designed for ISR 4000 Series routers (e.g., 4321, 4331, 4351, 4431, 4451). Verify slot and IOS XE support for your specific model.

Q: Does the port provide PoE or Layer 2 switching?
A: No. It is a routed WAN interface and does not supply PoE or act as a switch.
