Does the PacketShaper fiber-optic interface support the bypass function during power outage?
Last Updated May 13, 2017
Some Packetshaper models support the bypass function during power outage and some need an external fiber bypass switch.
For Fiber Optic Interfaces
The fiber-optic gigabit LEM used in all PS models except PS 12000 needs an external Fiber Bypass Switch to bypass traffic during the power down condition. However, if you have a PS 12000 with Fiber NICs, you do not need an external bypass switch; it has a built-in bypass capability. It is controlled by the bypss relay setting of 'close' or 'open.'
For Copper Interfaces
PacketShaper copper NICs supports bypass of the traffic during the power-down condition. Depending on the PS model, you either have to have the bypass jumpers closed or set the bypass relay to 'close.' (These are the default settings and allow uninterrupted traffic through the PS when power goes down; you do not need an external bypass switch.) When the power goes down, PS becomes a crossover cable connecting the switch and the router of the two connected devices.
