Ethernet Server
Bypass Adapter X520/X540 Family
Family supports three operational
modes: Normal, Bypass, and Isolate.
In Normal Mode, data travels into the
adapter and is processed by the host
server prior to being transmitted back
to the network. In Bypass Mode, the
LAN controller is disconnected from
the ports and the two external ports
are connected together into a single
pipe whereby packets received from
one port are then transmitted to the
other port, bypassing the host server
failure and maintaining network
connectivity. When needed, isolate
mode is available to ensure link is not
established. Intel® Ethernet Server
Bypass Adapters also include an on-
board programmable watchdog timer,
which gives administrators full control
to manage the mode of the adapter. In
addition, an event log provides the ca-
pability to document operation mode
changes based on different detection
conditions.

Bypass Mode
Dual-Port 10GbE Bypass Adapters enabling maximum network uptime and performance for mission-critical applications
Overview
Intel’s X520 adapters are known for
their high performance, low latency,
reliability, and flexibility. The addition
of the Intel® Ethernet Server Bypass
Adapter X520 and the Intel® Ethernet
Server Bypass Adapter X540 deliv-
ers all of the 10GbE performance in
addition to business continuity in the
event of a network failure. The bypass
capability removes a single point of
failure so that essential business com-
munication can continue while a sys-
tem failure is diagnosed and resolved.
In the event of a power, hardware, or
software failure, bypass will automati-
cally activate, allowing network traffic
to continue.
