This crosslink is disabled by default. This crosslink must be enabled for use.
Redundant paths to server bays
In a dual switch configuration, redundant Ethernet signals from each blade server are routed through the
enclosure backplane to separate switches within the enclosure. This configuration provides redundant
paths to each server bay.
Redundant Ethernet signals from each blade server are routed through the enclosure backplane to
separate switches within the enclosure. However, specific switch port to server mapping varies depending
on which type of server blade is installed.
On a heavily used system, using a single uplink port for 32 Ethernet signals causes a traffic bottleneck.
For optimum performance, HP recommends using at least one uplink port per switch.
