PBSSF-S-R Bypass Switch Stand Alone

10 /1 Gigabit (SM) Fiber Bypass Switch Stand Alone Unit

Silicom PBSSF-S-R is external Bypass switches for 10 /1 fiber Gigabit Ethernet networks. The Silicom Bypass switch protects from network failures and Network maintenance by ensuring network integrity during power loss.

Silicom Bypass switch includes Network ports, Monitor ports and control port. The Network ports are used to connect to Switch / Router Network connections.

The Monitor ports are used for an in-line networking device. The control port is used to control the mode of the Bypass switch. On power on, the mode of the Bypass switch is set to Normal, on power lose, the mode of the Bypass switch is set to Bypass.

Functional Description

In Normal mode, the Bypass switch diverts the data from the Network ports data to the Monitor ports.

BSSF-P1

In Bypass mode, the Network data traffic routed directly to the other Network portand the Monitor data traffic routed directly to the other Monitor port
