ProLiant BL p-Class Interconnect Overview - White Paper

Each interconnect kit includes two interconnects for one server blade enclosure. Each interconnect
itself consists of two hot-pluggable components, a front loading interconnect blade and a rear
mounted interconnect module that contains the network connectors. This modular design provides two
key benefits:
• The interconnect blade can be quickly and easily removed and replaced from the front of the rack
without the need for re-cabling.
• Interconnect switch can support copper or fiber Ethernet network uplinks by using different
interconnect modules. This design also allows the uplinks to be easily upgraded to future
technology.
RJ-45 Patch Panel and RJ-45 Patch Panel 2 Kits
The RJ-45 Patch Panel and RJ-45 Patch Panel 2 Kits each contain two patch panel interconnect blades
that allow Ethernet LAN signals to pass through to third-party LAN devices, thus giving customers
flexibility in choosing their own network switch, hub, or router. Both the RJ-45 Patch Panel and RJ-45
Patch Panel 2 Kits bring all 32 Ethernet signals out as separate RJ-45 connections through two rear-
mounted LAN interconnect modules per patch panel device. Both kits support the BL20p and BL20p
G2 server blades (shown in Figure 5), the BL40p server blade, or a combination of these servers.
In addition to Ethernet signal pass-though, the RJ-45 Patch Panel 2 Kit provides 16 Fibre Channel front
panel ports to support signal pass-through for up to eight ProLiant BL20p G2 servers with two Fibre
Channel ports each

. The ProLiant BL40p server blade does not require Fibre Channel signals to be
routed to the interconnect bays.
