Verifying Component Operation - Seagate RealStor 5005 Series Hardware Installation

NOTE: When performing the following procedure, refer to
installation, the IOM will travel in the opposite direction relative to the arrow shown.
1. Examine the IOM for damage, and closely inspect the interface connector. Do not install if the pins are bent.
2. Grasp the IOM using both hands, and with the latch in the open position, orient the module and align it for insertion
into the target IOM slot.
3. Ensuring that the IOM is level, slide it into the enclosure as far as it will go.
A controller module that is only partially seated will prevent optimal performance of the controller enclosure. Verify
that the controller module is fully seated before continuing.
4. Set the module in position by manually closing the latch.
You should hear a click as the latch handle engages and secures the IOM to its connector on the back of the
midplane.
5. Reconnect the cables.
NOTE: In a dual-controller system in which PFU is enabled, when you update the firmware on one controller, the
system automatically updates the partner controller.

Verifying component operation

Controller module
After replacing the controller module, verify that the CRU OK LED (rear panel) illuminates green, indicating that the
controller has completed initializing, and is online/operating normally. It may take two to five minutes for the replacement
controller to become ready. If you are replacing either controller module, and PFU is enabled, you may need to wait 30
minutes to ensure that the two controllers—with their respective ownership of the disk groups—have enough time to
fully stabilize.
IMPORTANT: Use the SMC or CLI to perform a restart only if necessary. See the "Restarting controllers "topic in the
Storage Management Guide for more information.
Expansion module
If the storage system is configured with expansion enclosures, the replacement expansion module may take up to one
minute to initialize after the cables are connected.
