Installing An Fcm; Replacing An Iom; Removing An Iom - Lenovo ThinkSystem DS Series Hardware Installation And Maintenance Manual

IMPORTANT: The FCM slot must not be empty for more than 2 minutes while the enclosure is powered.

Installing an FCM

1. You can hotswap the replacement of a single FCM; however, if replacing multiple FCMs, the enclosure must be
powered off via an orderly shutdown using the management interfaces.
2. Orient the FCM for insertion into the target slot on the enclosure rear panel, as shown in
3. Slide the FCM into the slot until the latch clicks home.
The enclosure should automatically detect and make use of the new module.
4. Wait for the Module OK LED on the newly inserted FCM to illuminate green. See also
If the Module OK LED does not illuminate, verify that the FCM is properly inserted and seated in the slot.

If properly seated, the module may be defective. Check the SMC and the event logs for more information.

Using the management interfaces (the SMC or CLI), determine if the health of the new FCM is OK. Verify

that the Module OK LED is green, and that the Ops panel states show no amber module faults.

Replacing an IOM

DS Series and DS EXP/D3284 supports a common set of controller modules in 2U RBODs, and a common
expansion module in 2U and 5U enclosures configured as EBODs. Be mindful of the intricacies associated with
enclosure IOMs before engaging in replacement. Key considerations pertaining to replacement of a controller
module are described on the following pages.
• Important and ensuing discussion on
• "Before you begin" (page 127)
• "Configuring partner firmware update" (page 128)
•
"Verifying component failure" (page 128)
•
"Stopping I/O" (page 128)
•
"Shutting down a controller module" (page 129)
NOTE: Given that the 5U84 is configured exclusively as an EBOD, the replacement procedure is specific to an
expansion canister. See also the topic about updating expansion module firmware within the Storage Manager
Guide.

Removing an IOM

IMPORTANT: Considerations for removing expansion modules:
• Do not remove a faulty module unless its replacement is on-hand. All modules must be in place when the
system is in operation.
• In a dual-IOM environment—if replacing both expansion modules—power off the expansion enclosure before
replacing the two IOMs. Power on the EBOD after replacing both canisters. See
(page 92).
