Replacing an Enclosure
The enclosure consists of an enclosure’s metal housing and the midplane that
connects controller/expansion modules, drive modules, and power-and-cooling
modules. This FRU replaces an enclosure that has been damaged or whose midplane
has been damaged. Often times a damaged midplane will appear as though a
controller module has failed. If you replace a controller module and it does not
remedy the original fault, replace the enclosure.
To make a fully functional enclosure, you must insert the following parts from the
replaced enclosure:
■
Drive modules and air management modules
■
Two power-and-cooling modules
■
One or two controller modules (for a controller enclosure)
■
One or two expansion modules (for a drive enclosure)
To install the individual modules, use the replacement instructions provided in this
guide. To configure the enclosure, see the
getting started guide . The IP address for
the controllers is maintained on the midplane. When you replace the enclosure, you
need to reset the IP address as described in the
getting started guide .
Caution – If connected data hosts are not inactive during this replacement
procedure, data loss could occur.
