10Gb Ethernet Pass-Thru Module for IBM BladeCenter
IBM Redbooks Product Guide
The 10Gb Ethernet Pass-Thru Module for IBM BladeCenter is ideal for clients looking to enable
end-to-end non-blocking 10Gb setup within the chassis. This device supports both Ethernet and
Converged Enhanced Ethernet (CEE ) packets, which allows clients to connect a BladeCenter Chassis to
an FCoE-capable top-of-rack switch.
The 14 10Gb Uplink ports are based on optical SFP+ technology to offer the highest performance while
maintaining industry standard connectivity. This offering will also work with BladeCenter Open Fabric
Manager, providing all the benefits of I/O Virtualization at 10Gb speeds.
Figure 1 shows the pass-thru module.

Did you know?
Clients can use this module along with the 2-port 10Gb Converged Network Adapter (CNA) and connect
to a converged top-of-rack switch such as the IBM Converged Switch B32. This setup allows clients to
reduce hardware, as well as power and cooling costs, while boosting performance by operating at 10Gb
bandwidth.

Popular configurations
The 10Gb Ethernet Pass-Thru Module can be used in the following configuration.
Two-port configuration with FCoCEE support
Figure 2 shows the use of 10Gb Ethernet Pass-Thru Modules to route two Ethernet ports from QLogic
2-port 10Gb Converged Network Adapter (CFFh) installed into each server. Two 10Gb Ethernet
Pass-Thru Modules are installed in bay 7 and bay 9 of the BladeCenter H chassis. All connections
between the controller, card, and the switch modules are internal to the chassis. No internal cabling is
needed. External (Top Of Rack) switches that support FCoCEE and cabling are required for the pass-thru
module to operate.

Connectors and LEDs
The following figure shows the front panel of the 10Gb Ethernet Pass-Thru Module and the numbering of
the ports when installed in a BladeCenter H chassis. When the module is installed in a BladeCenter H
chassis, the ports and LEDs are numbered from right to left, as shown in the figure.
Figure 3. Front panel of the 10Gb Ethernet Pass-Thru Module for BladeCenter H chassis
The following figure shows the numbering of the ports when installed in a BladeCenter HT chassis. When
the module is installed in a BladeCenter HT unit, the ports and LEDs are numbered from left to right, as
shown in the figure.
Figure 4. Front panel of the 10Gb Ethernet Pass-Thru Module for BladeCenter HT chassis
The front panel contains the following components:

LEDs display the status of the pass-thru module and the network:

OK (indicating that the switch module has passed the power-on self-test (POST) with no critical
faults and is operational)

Pass-thru module error (indicating that the switch module has failed the POST or detected an
operational fault).

14 SFP+ port connectors to attach SFP+ modules.

Each external SFP+ port on the pass-thru module contains an link status LED - the port number
associated with each LED is indicated in Figures 4 and 5.
