Two MSEBs Needed for Each Server

Each server that will join a ServerNet cluster must have at least two modular ServerNet

expansion boards (MSEBs). These MSEBs must be installed in slots 51 and 52 of the

group 01 enclosure. (Other enclosures do not need MSEBs.)

Check the CRUs installed in group 01, slots 51 and 52 to determine if they are SEBs or

MSEBs. Figure 2-2 shows the location of these slots.

Note. If you have a two-processor system (for example, a NonStop S700) with ServerNet

adapters installed in group 01, slots 51 and 52, you must move the adapters so that MSEBs

can be installed in these slots. You might have to purchase an additional system enclosure in

which to install the moved adapters. For instructions on moving the ServerNet adapters, refer

to the manual for each adapter.
