Replace a 2U enclosure input/output module
Each input/output module (IOM) receives the flow of data managed by the host system. Each IOM provides a very specialized,
solutions-specific interaction that depends on your system configuration and software implementation, including SAS zoning,
failover and failback procedures, and multipath procedures.
An important feature of the 2U enclosure design is redundancy. The 2U enclosure will maintain continuous operation during
the replacement of a single IOM, as long as it is within the time limit of 5 minutes, since removal of an IOM significantly reduces
airflow in the 2U enclosure.
CAUTION If you remove any FRU while the expansion enclosure is powered up, you must replace it with a tested good
spare within the allotted time for that FRU. If you do not replace the FRU within the identified time limit, you void the product
warranty and the expansion enclosure might overheat, causing equipment failure and possible data loss.
CAUTION Do not remove covers from any FRU. There is a danger of electric shock inside. Return the FRU to your
supplier for repair.
The IOM has a number of ports, each with independent status LEDs. Those items in the state column with an asterisk (*)
indicate a fault condition.
