Modern Hardware for a New Take on a Classic-ISR 900 Series

The new ISR 900 Series builds on that solid foundation with rock-solid 21st century hardware. 

The Cisco 900 Series is a silent, fan-less chassis designed to fit into any office. With that comes the interfaces you need today including LTE (available soon), ADSL/VDSL, Gigabit Ethernet WAN and switching. Modern components bring Cisco IOS performance on par with current branch routers including high performance encrypted VPN and firewall. Thousands of features you expect from a Cisco Branch Router, including some the 2500 never dreamed of, are built in such as MPLS, IPSLA, AVC, PfR and more with performance that’s more than 100 times what the 2500 could dream of.

Learn More: The New Cisco’s SOHO Routers-ISR 900

There’s also one more throwback to classic small branch routers you might notice in the new Cisco 900 Series ISR and that’s the internal power supply. The Cisco 921 & 931 ISRs do away with the external power supply “brick” common to branch office devices and brings the power supply inside the router which can really clean up a cluttered branch environment. Getting the power supply inside a passively cooled chassis with a wide temperature range is a big engineering deal. 

The Cisco 900 Series is a modern classic. It complements other members of the ISR portfolio, such as the ISR 1000 Series and ISR 4000 Series, while providing an easy migration path for Cisco 800 Series users. It isn’t the fastest or flashiest member of the ISR family. What it is is a solid, reliable performer with the features you need to sort out the most complex of network nightmares.
