FAQs

Q: Does the LAN switch provide PoE?
A: No. The 8x Gigabit LAN ports are non‑PoE.

Q: Which SFP modules are supported for the WAN port?
A: Standard 1G SFPs such as SX, LX, and 1000BASE‑T copper are typically supported. Check the platform SFP compatibility list for specific part numbers.

Q: Is SD‑WAN supported on this model?
A: This ISR runs classic Cisco IOS and does not support Cisco SD‑WAN. It supports traditional VPN (e.g., DMVPN, IPSec) depending on licenses.

Q: Is the wireless access point dual‑band?
A: It includes 802.11n Wi‑Fi. Band support is model/region dependent; consult the specific regulatory domain documentation.

Q: Can it be rack‑mounted?
A: It is a desktop unit. Use a shelf or third‑party rack bracket if rack installation is required.
