Blade Server Ethernet Controller Enumeration - IBM QS21 - BladeCenter - 0792 Service Manual

Blade server Ethernet controller enumeration

The enumeration of the Ethernet controller or controller ports in a blade server is
operating system dependent. You can verify the Ethernet controller or controller port
designations that a blade server uses through your operating system settings.
The routing of an Ethernet controller or controller port to a particular BladeCenter
unit I/O bay depends on the type of Ethernet expansion card that is installed. You
can verify which Ethernet-controller port in this blade server is routed to which I/O
bay by using the following test:
1. Install only one Ethernet switch module or pass-thru module, in I/O bay 1.
2. Make sure that the ports on the switch module or pass-thru module are enabled
3. Enable only one of the Ethernet-controller ports on the blade server. Note the
4. Ping an external computer on the network connected to the Ethernet switch
Communications from optional I/O expansion cards are routed to I/O bays 3 and 4.
If you have installed an I/O expansion card on the blade server you can verify
which controller port on an expansion card is routed to which I/O bay by performing
the same test, using a controller on the expansion card and a compatible switch
module or pass-thru module in I/O bay 3 or 4.

module. If you can ping the external computer, the Ethernet-controller port that
you enabled is associated with the switch module in I/O bay 1. The other
Ethernet-controller port in the blade server is associated with the switch module
in I/O bay 2.
