Gigabit Ethernet security router with VDSL2/ADSL2+ bonding over POTS, SFP slot, and 8-port switch
The Cisco 897VA combines a VDSL2 and ADSL2+ modem, an 8-port Gigabit Ethernet switch, three WAN interfaces and an SFP slot in a single desktop appliance. It is built for small offices or branch sites that need secure broadband connectivity without separate boxes. The integrated firewall and VPN features protect traffic across the WAN links.
When both VDSL2 pairs are bonded the router maintains the negotiated line rate continuously, handling encryption and inspection without the short bursts seen on single-pair links. The Gigabit Ethernet switch ports forward at line speed during extended file transfers or backup windows. The SFP uplink remains stable under long-duration traffic loads.
Confirm the service provider delivers VDSL2 or ADSL2+ over standard copper pairs, because the built-in modem does not support fibre or cable hand-off. Check that the single expansion slot matches any planned module such as a second WAN interface. Ensure the 12.7-inch width and 8.8-inch depth fit the available rack or shelf space.

The router operates on standard mains power with no separate supply voltage listed; typical consumption for this class stays well within a normal office circuit.
It requires a live VDSL2 or ADSL2+ line over copper POTS, or a fibre link via the SFP slot, plus at least one Ethernet cable for the LAN side.
Yes, the Gigabit Ethernet ports auto-negotiate down to 10/100 speeds, so older 100 Mbps gear connects without configuration.
