1.2.6 BladeCenter 4-Port Ethernet Switch Module
The Ethernet Switch Module (Figure 1-10 on page 13) has several purposes; in addition to
providing network connectivity for the IBM Eserver BladeCenter and blades, it also provide
interconnectivity between the blades and management modules. The Ethernet switch module
does not come standard with the IBM Eserver BladeCenter; it is available for purchase as
an option but it is required in most cases and should be installed in switch bay 1. This module
is a fully functional Ethernet switch which has four 1000 Mbps ports externally, two internal
10/100 Mbps links to the management modules and fourteen 1000 Mbps links to the blades,
which are also internal. Two of these switch modules can be added for redundancy. The
switch module is configured via the Management Module.
