Silicom 100G Intelligent QSFP28 Bypass switch (IS100) is Silicom forth generation of an active external Bypass switch that protects network integrity from network failures and network maintenance. The Silicom intelligent Bypass switch (IS100) is a self-generating heartbeat and controls the network switch mode of operation.

The Silicom IS100G1U is a 1U host system which supports up to two modules. A module supports one Bypass segment per module.

The Silicom IS100 supports 100 Gigabit Ethernet Multimode Fiber (100GBase-SR4) ,(100G Base-SR10 ) and 100 Gigabit Single mode fiber (100GBase-LR4) network standards. Each 100G Bypass module includes two MPO / LC ports for network ports, and two QSFP28 ports for the attached in-line network system.

The Silicom Intelligent Bypass switch (IS100) supports four modes of operations: Inline, Bypass, Tap and Linkdrop. In Inline mode, the IS100 diverts inline network traffic to attached in-line network system. In Bypass mode, the IS100 does not divert the traffic to the attached in-line network system and diverts it to other network link. In Tap mode, incoming traffic in port NET0 is mirrored to port MON0 and incoming traffic in port NET1 is mirrored to port MON1.In Linkdrop mode the IS100 disables the links on the network ports (NET0, NET1). The IS100 simulates switch / router cable disconnection.

The IS100 generates the heartbeat packets and transmits the heartbeat packet to the in-line Monitor / Network appliance port, the Monitor Network appliance receives the heartbeat packets and transmits is to its other port (bridges the heartbeat packet). The IS100 detects back the heartbeat packet and maintains the Inline mode.

The IS100 sets to Bypass, Tap or Linkdrop when it does not receive back the heartbeat packet from the Network / Monitor appliance. When the Network / Monitor appliance recovers, it transmits back the heartbeat packet and the Intelligent switch sets to Inline. The IS100 bypasses its Ethernet Monitor ports on event of power failure, Link failure, in-line software application system hang or user request.

The IS100 includes Double Bypass Safe architecture. The Silicom Double Bypass safe architecture is based on two Bypass routing circuitry: An Active Bypass circuitry and Passive Bypass circuitry. If the internal active bypass routing circuitry fails, the passive Bypass routing circuitry is activated.
The IS100 can be configured using:
• Simple CLI configuration management via a serial communication console port, Ethernet port using Telnet or SSH.
• Web interface management interface.
• SNMP.

The Silicom IS100 Bypass switch includes centralized management to all Bypass segments in the box.
The IS100G includes two redundant 90 – 240 V AC power supply or two redundant -48 DC power supply.
