Verify that the new part is recognized by your system, and operating correctly.
Steps
1. In Unisphere, select System View.
2. On the Summary page, confirm that the system status is OK.
3. Select the Enclosures page.
4. Verify that the part appears with the OK status in the enclosure view. You may need to refresh Unisphere by clicking on the

If the system health monitor shows the part as faulted, contact your service provider.

Add a 4-port card

Take the following actions to install a new 4-port card into the system.

Preparing the SP assembly for service

About this task
Reset and hold is a special state during which power is maintained to the SP assembly so that I/O modules, embedded modules,
and 4-port cards can be safely removed. This state has fewer management capabilities than Service Mode, but allows for easier
I/O module, embedded module and 4-port card replacement.
NOTE: Both SP assemblies must NOT be in reset and hold simultaneously. The system should be up for at least 40 minutes
since its last reboot before being placed into reset and hold.
NOTE: Do not add or reseat NVMe Flash drives when the system is in the reset and hold state.
Steps
1. Open Unisphere and select Service, then Service Tasks.
2. Under the name of the SP assembly where you will install the new I/O module, embedded module or 4-port card, select
Reset and Hold and then click Execute.
3. When prompted, type the service password to put the SP assembly into reset and hold.
4. Optional: Either refresh the browser or follow the onscreen instructions to restore full-functionality to Unisphere.
When placing the primary storage processor into hold in reset, Unisphere becomes momentarily unresponsive as the
management services transfer over to the other SP. After about 10 minutes, the SP assembly's status will change to
Degraded, and indicate that the SP assembly has been placed in held in reset. The SP assembly's status can be confirmed by
checking the log entries in Unisphere under Events > Alerts.
5. Wait until the SP assembly fault LED and power indicator LED are lit solid amber and green, respectively, and the peer SP
assembly's Unsafe to Remove LED is lit before moving to the next task.
