The replacement procedure should be completed within an absolute maximum of 3 minutes.

Enclosure management

IOMs/EBOD expander modules actively manage the enclosure. Each module has a SAS expander with its
own storage enclosure processor (SEP) that provides a SES target for a host to interface through the ANSI
SES Standard. If one of these modules fails, the other module will continue to operate.
Refer to a module's specification or the SES Interface specification for definitions of the module's
functions and its SES control.
The storage system also provides a command-line Interface (CLI).

Command-line interface

The command line interface can be accessed in the following ways:
• Serial port connection
• Ethernet Telnet connection
• Ethernet WBCLI utility
• SESCLI utility
