Routing, Switching and VOIP,

Based on CISCO 5915 Embedded Service Router (ESR)

Ruggedization is a key feature with a lightweight, milled aluminum enclosure and dustcaps for all ports.


The VoyagerESR is the core routing and switching module in the Voyager networking system. It has more capability in a smaller form factor than any other networking module on the market. It contains a Cisco 5915 ESR with a Klas-designed switch for increased capability and function. The VoyagerESR has a milled aluminum enclosure, is fully rugged with no internal cabling, moving parts, or fans, and can even be placed in an IP67, MIL-STD 1275D-compliant enclosure. VoyagerESR has been environmentally tested according to MIL-STD-810G and passed its multiple methods.

VoyagerESR’s feature set includes:

  • Fanless design with dustcaps for increased ingress protection and improved reliability
  • 12x Fast Ethernet switch (4 with PoE)
  • 2x Fast Ethernet routed ports
  • 2x FXS ports
  • Optional Voyager Ignition Key (VIK) removable storage to support eToken-like reconfiguration
  • Cellular/Wi-Fi/Harris radio tethering
  • Optional cellular core network
  • Integrated UPS/2+ hour battery backup, DC out for a range of HAIPE devices (with Voyager 1 battery)
  • The battery-backed NTP server accessible to Cisco 5915 ESR


VoyagerESR has 38% the volume, 57% the weight and approximately 25% the power of its nearest SWaP competitor (when comparing just the routing, switching and power features). See our video on how the competition stacks up.
