Silicom Managed Bypass Switch is designed for 10 / 1 Gigabit Ethernet networks. The Silicom managed Bypass switch is targeted to maintain network connectivity when the in-line system fails. The Managed Bypass switch is based on reliable a passive switch, console management port and on board watch dog timer controller.
Silicom Managed Bypass switch supports two modes of operations: Normal and Bypass. In Normal modes, the Bypass switch diverts the network traffic to attached in-line network system. In Bypass mode, the inline traffic is diverted to the network link and no longer routed to the in-line device. The Managed Bypass Switch can be programmed to Bypass its Ethernet ports on event of power fail, Link fail or user request.
The Silicom Managed Bypass switch includes an on board Watchdog timer controller (WDT) and a passive switch. The on board WDT controller can receive heartbeat “alive” packet via its serial communication console, USB, or its Ethernet port (selected models).
The Silicom Managed Bypass switch can be shipped as a stand alone unit (BSS) or as a rackmount 1U host system (BS1U). The rackmount 1U host system support up to four Bypass modules. Each Bypass module supports a Bypass segment. The Bypass modules in the 1U host system can be chained in order to enable multi-Bypass segment to support systems with limited management accessibility.
Stand Alone unit
TThe Silicom Managed Bypass switch a stand-alone flavor includes four 10 /1 Gigabit Ethernet data ports. Console management include Serial ( RJ11), USB and Ethernet port (selected models). The stand-alone flavor includes an external +12V power supply.

1U Rackmount host system
The 1U host system that supports up to four Bypass Switch modules. The Bypass switch host includes two redundant internal dual 110 – 220 V AC power supplies.
The Silicom Managed Bypass switch host supports two types of Bypass switch modules, a controller (-C) and a slave (-S). A controller Bypass switch (-C) module includes data ports and management ports. A slave module includes data ports only. A controller Bypass module ( -C) and a slave Bypass module can be chained 1U host system. The chain of modules was designed in order support systems with limited management accessibility that requires multi-Bypass segment configurations.
