module that contain a 10-Gb Ethernet high-bandwidth uplink. The 10-Gb LAN interconnect modules 
may also contain Gigabit Ethernet ports, if space permits. 
With these future planned options for the GbE2 Interconnect Switch, an administrator will be able to 
independently select the switching layer as well as the uplink bandwidth, all within a single switch. 
Both options can be installed by users in the field without powering down the server blades or the 
server blade enclosure. Availability of these options will be announced in the near future.

Crosslink ports 
The two GbE2 Interconnect Switches are connected through a pair of redundant, 10/100/1000 
Mb/s Gigabit Ethernet crosslink connections that are bundled in a 2000 Mb/s Cisco EtherChannel 
compatible multi-port trunk. The signals are routed as Ethernet from switch to switch via individual 
CAT5e specified signal traces on the passive backplane assembly of the server blade enclosure. The 
crosslinks permit communication between the switches, if desired. They also provide the ability to: 
 
Manage both switches, perform PXE server boots, and access all iLO interfaces using any number 
of external switch ports. Therefore, a single switch uplink can be used to perform all Ethernet 
management tasks. 
 
Configure the p-Class system for advanced ProLiant Network Adapter Teaming including switch 
fault tolerance. See the section “ProLiant Network Adapter Teaming” for additional information. 
 
Communicate with any server network adapter from any switch uplink port. As a result, any single 
uplink port may be used to communicate to all 32 NICs. This permits the 32-to-1 cable reduction 
and provides additional system redundancy. If uplinks on one switch or the connection to a switch 
were to fail, all NICs still can be accessed via the other switch. 
Maximizing network cable reduction 
For maximum (97 percent) cable reduction, the 32 Ethernet signals within the server blade enclosure 
can be concentrated into any one external Ethernet port. This results in a total of six Ethernet 
connections for a fully configured 42U rack of six server blade enclosures containing 192 network 
adapters.
