● When you replace a compute sled, with a service tag, with a compute sled of another service tag, and the storage sleds are
mapped to the compute node slot, the power on the particular compute sled is turned off. An option to unblock power is
displayed on the Devices > Compute > Overview page for the compute sled.
● When you remove a compute sled, containing an HBA 330 controller with shared mappings, and replace it with a compute
sled containing a PERC controller, the sled is checked to ensure that no shared mappings exist. If shared mappings exist, a
message is displayed on the Devices > Compute > Overview page for the compute sled, prompting you to clear the
mapping. The compute sled is turned off.
● When you remove a compute sled containing a PERC controller with mappings, and replace it with a new compute sled
having an HBA 330 controller with a different service tag, a message is displayed on the Devices > Compute > Overview
page for the compute sled, prompting you to clear or accept the mapping. However, the compute sled is turned on in this
scenario.
The following flowchart and table illustrate the behavior of OME-Modular and the LCD panel on the chassis when the compute
sled is replaced:

Case 1 Enables users to clear all mappings to
the compute sled.
Enables users to clear all mappings to
the compute sled.
Case 2 Enables users to clear or retain all
mappings to the compute sled.
Enables users to clear or retain all
mappings to the compute sled.
Viewing compute hardware
You can view the details of the hardware components that are installed in the compute sled, on the compute Hardware page.
The hardware components include processor, storage controller, and FRU.
The deployment and configuration jobs on the compute sled are performed only for the first time, if the profile and sled device
ID are unchanged. If the sled is removed and reinserted, the deployment and configuration job is not performed. This condition is
applicable to the Edit Profile task too.
NOTE:
If the storage controller cards are absent in iDRAC, the storage enclosure details are not displayed on the Compute
> View Details > Hardware > Storage Enclosure page.
