Security Gateway Modules

The Security Gateway Modules (SGMs) in the Chassis work together as a single, high performance Security Gateway or VSX Gateway. Adding a Security Gateway Module scales the performance of the system. A Security Gateway Module can be added and removed without losing connections. If an SGM is removed or fails, traffic is distributed to the other active SGMs.

These SGM versions are available:

• SGM220 (Not supported in a 4-SSM configuration or the 41000 Security System.)
• SGM220T (for NEBS only - Not supported for the 41000 Security System)
• SGM260 (Supports 4-SSM configuration )

The SGM260 has more powerful CPUs and uses a more advanced technology. It also has a different front panel layout and different LEDs.
