support.dell.com Configuring Your ESEM or SEMM for Cluster Operation 4-3
To configure the ESEMs or SEMMs from a cluster operation to a noncluster opera-
tion, perform the following steps on each module:
1. Remove the ESEM or SEMM.
2. Locate the two-pin jumper labeled "FORCED JOINED JP8" on the ESEM or
SEMM (see Figure 4-1).
NOTE: Only the FORCE JOINED JP8 jumper has a jumper plug installed. The
Dell-installed defaults for jumpers JP1, JP2, JP6, and JP7 are NO jumper plugs
(empty).
3. Move the jumper plug to connect only one pin of the FORCED JOINED JP8
jumper (see Figure 4-1).
4. Install the ESEM or SEMM in the PowerVault 2xxS storage system.
