Modular ServerNet Expansion Boards (MSEBs)
Figure 1-9 shows an SEB and an MSEB.
An MSEB connects either to the X fabric or to the Y fabric, but never to both. MSEBs
allow the connection of fiber-optic cables from the server to the cluster switches. At
least two MSEBs must be installed in each node of a ServerNet cluster. The MSEBs
must be installed in the group 01 enclosure in slot 51 (for the X fabric) and slot 52 (for
the Y fabric). MSEBs do not need to be installed in other enclosures.
