Secure Serial Console Servers


Remotely manage servers and network devices ensuring maximum network uptime

Network uptime is critical for most global corporations today for sales, operations, production, and communication activities.  Outages can be extremely costly.  While software management tools can be used for performance monitoring and some remote troubleshooting, they only work when the network is up. For a more reliable solution, large corporations turn to out-of-band management with console servers. Network engineers can use OOB with console servers to reconfigure, reboot and reimage remotely across the internet or WANs even if the primary data network is down.

Console servers are a good solution for large distributed enterprises with multiple branches— such as banks, insurance companies, hospitals, utilities, retail and school systems— that may not have IT staff on-site. Network administrators can choose from a wide range of port densities to suit the application. For example, one console server may have as many as 48 serial ports for remote management of assets in data centers. Other console servers may have just four ports and are suited for connecting LAN switches and routers in data closets.

Cisco ISR 2900 Series Routers EOL Replacement

If your customers have a need for a high-density terminal server and they have always relied on the Cisco 2900 or any ISR router, ask them to look at the Black Box LES1600 and LES1700 series console servers. These devices are embedded with innovative OOB technology and are purpose-built to provide terminal/console server access. They can easily be substituted into new or existing data centers and come in various port densities ranging from 4 to 48. The Black Box console servers are designed specifically to work with Cisco equipment.

Cisco recommends the ISR 4000 series as an alternative to the ISR 2911 combined with NIM modules. With our LES1700 solution, you can connect up to 48 devices with an embedded PSTN modem and/or cellular. The new ISR 4000 can only connect up to 32 devices in the same 1 RU configuration.
