Storage expansion enclosure settings

This section provides information about storage expansion enclosure settings. For
additional detail, refer to the Installation, User's, and Maintenance Guide for your
storage expansion enclosure.

Fibre channel loop and ID settings

When you install an E-DDM in the storage expansion enclosure, the E-DDM tray
plugs into a printed circuit board called the midplane. The midplane sets the fibre
channel loop ID automatically, based on the enclosure ID switch setting and the
physical location (bay) of the E-DDM.

DS4000 storage expansion enclosure ID settings

Some DS4000 storage expansion enclosures, such as the EXP710 and EXP100,
have an enclosure ID switch that is used to identify the DS4000 storage expansion
enclosure on a fibre channel loop. The enclosure ID switch is located on the back
of the unit. Other DS4000 storage expansion enclosures, such as the EXP810, do
not have an enclosure ID switch because the controller automatically sets the
enclosure ID number.
