Two MSEBs Needed for Each Server
Before an MSEB can replace an SEB, the MSEB must be populated with plug-in cards
(PICs) to accept the ServerNet cables previously attached to the SEB. For example, if
four ECL ServerNet cables are attached to a SEB, the MSEB that replaces it must
contain four ECL PICs in the ports to which the cables connect. Figure 2-5 compares
the supported SEB and MSEB connectors.
ServerNet Cables for Attaching MSEBs to Other System
Enclosures
Replacing SEBs with MSEBs also requires you to replace the ServerNet cables
connecting the SEBs to other system enclosures. The number and type of cables you
need depend on the number and type of PICs installed in the MSEBs. The following
table shows the ServerNet cables required for the supported PIC connectors:
Appendix A, Part Numbers, lists the available ServerNet cables.
