Bypass Module
Bypass module connects two networks. Data between them are transferred by the
device in the normal condition. When a specific incident occurs (like sudden power
failure or system reboot), the two networks are connected directly by the bypass
module, therefore, the device is bypassed. You can install bypass module(s) in
general expansion slots. For more information about Bypass configuration, please
refer to
StoneOS User Manual
.
Hillstone bypass module has the following two types:
Single-mode bypass module: IOM-2SM-BE
Multi-mode bypass module: IOM-2MM-BM
SG-6000-X7180 uses IOM-2SM-BE and IOM-2MM-BM modules.
