Low SWaP, Layer 3 Ethernet switch + PoE + removable configuration storage
Listed on the NIAP CSfC Product Compliant List

The Voyager Embedded Switch m-Series (VoyagerESm) contains the same Layer 3 switch designed by Klas Telecom but has fewer ports for reduced SWaP operations. It contains 4 Fast Ethernet ports, all of which are PoE enabled, a Gigabit Ethernet switch port, 2 USB 2.0 ports, console management port and a removable configuration storage for increased security, persona portability and simplified sparing.

The VoyagerESm supports critical Cisco VoIP switching features such as VLAN trunking and Cisco Discovery Protocol (CDP).

Ruggedization is a key feature of the VoyagerESm with a lightweight, fanless design and an extruded aluminum enclosure with dust caps for all ports.

A CSfC Solution

The VoyagerESm is listed on the NIAP Product Compliant List (PCL) making it a viable CSfC solution for government customers.

Klas’s VoyagerESm is a core component of the Voyager Executive

Communications Kit (VoyagerECK), a discreet and portable VoSIP and multi-enclave data communications package that connects executives on the move with the secure resources they need. The VoyagerESm passing common criteria allows the VoyagerECK to be used as a CSfC solution.
