Table 5. Hot-swap I/O module types by location for redundancy (continued) Bays I/O-module function Permissible I/O module 3 and 4 Network connections 3 and 4 (for all I/O expansion options on blade servers in the BladeCenter T unit) One of the following combinations. v Two Ethernet switch modules v Two Fibre Channel switch modules v Two pass-thru modules Important: v The modules used must support the network interface that is used on the blade server I/O expansion options. v The I/O modules in bays 3 and 4 must be the same type. Notes: 1. The enumeration of the Ethernet controllers in a blade server is operating-system dependent. You can verify the Ethernet controller designations that a blade server uses through your operating-system settings. 2. The routing of an Ethernet controller to a particular I/O-module bay depends on the type of blade server. You can verify which Ethernet controller is routed to which I/O-module bay by using the following test: a. Install only one Ethernet switch module or pass-thru module, in I/O-module bay 1. b. Make sure that the ports on the switch module or pass-thru module are enabled (I/O Module Tasks " Management " Advanced Management in the management module Web-based user interface). c. Enable only one of the Ethernet controllers on the blade server. Note the designation that the blade server operating system has for the controller. d. Ping an external computer on the network that is connected to the switch module or pass-thru module. If you can ping the external computer, the Ethernet controller that you enabled is associated with the I/O module in I/O-module bay 1. The other Ethernet controller in the blade server is associated with the I/O module in I/O-module bay 2. 3. If you have installed an I/O expansion option on a blade server, communications from the option are routed to I/O-module bays 3 and 4. You can verify which controller on the option is routed to which I/O-module bay by performing the test in note 2, using a controller on the I/O expansion option and a compatible switch module or pass-thru module in I/O-module bay 3 or 4. Use the instructions in this section to remove or install an I/O module at the rear of the BladeCenter T unit. Chapter 4. Setting up the BladeCenter T hardware 61
