Bypass Units
The AC-2500 series operates with an external Bypass Unit. The Bypass Unit is a
mission-critical subsystem designed to ensure network connectivity at all times. The
Bypass mechanism provides "connectivity insurance" in the event of a NetEnforcer
subsystems failure.
The NetEnforcer is supplied with an appropriate Bypass Unit. The AC-2520 Fiber
operates with a Double Fiber Bypass and the AC-2520 Copper operates with a Double
Copper Bypass. The AC-2540 operates with a Multi-port Fiber Bypass.
CAUTION
A
NetEnforcer AC-2500 unit must be connected to the appropriate
Bypass Unit. This is to ensure continuous service in the event of
failure.
A separate NetEnforcer Bypass package is included with your AC-2500 series
shipment.

The Double Copper Bypass Unit includes RJ-45 connectors for Ethernet cables and
D-type 9-pin connectors for primary and redundant unit to backup connection.
