CS Uni2

The COMSEC Uni-Shelf (CS Uni2) iGov Variant is a unique shelving solution that rigidly mounts various Type 1 COMSEC devices and IAS IP networking appliances within a standard 2U IT rack space.

The CS Uni2 is easy to use and affordable, allowing complete flexibility when configuring rack space. Its flexible design supports the retention of several different vendors’ COMSEC products, IP networking appliances and the mixing and matching of various vendors’ products. This allows organizations to simply inventory a single shelf and use it for several products/applications.

All necessary hardware (bolts & washers) required to retain the list of supported devices is included.

A CS Uni2 Strapping Kit is also available (sold separately). It is used to retain first generation KG- 250s, KIV-7Ms, or KIV-19Ms (which all lack hard mounting points).

CS FO175

KG-175 Failover Adapter

The CS FO175 has been designed and developed specifically to meet the needs of users who require a high reliability power supply solution for the KG-175 family of HAIPE devices. Customers who implement the CS FO175 will have peace of mind knowing that their KG-175 A, B, D or G HAIPE device will remain powered and online in the event of a power supply failure. The CS FO175 uses two power supplies in a failover arrangement so if one of the two power supplies fails, the KG-175 device will remain powered by the second power supply. It does this instantaneously and automatically with no user interaction. The CS FO175 utilizes either the KG-175 OEM power supply or the highly reliable power supplies that we produce specifically for the KG-175 family and works with either the KG-175A, B, D, and G HAIPE devices.
