Sun Microsystems SG-XPCIE20FC-NEM-Z manual Replacing a NEM, To Install the ID Chip Patch

Replacing a NEM

If a NEM fails or if you choose to change the I/O configuration, you will need to replace it. You can remove and replace a NEM from a powered-on system using a hot-plug operation, as well as from a powered-off system. When you remove a NEM, you must replace the module within two minutes to prevent adjacent modules from overheating.

If you are removing but not replacing the NEM, you also must install a NEM filler panel to meet FCC limits for electromagnetic interference (EMI) and to ensure proper airflow and cooling. If you encounter a problem with the NEM replacement, see the Sun Blade 8000 Series Online Help System for troubleshooting steps.

▼To Install the ID Chip Patch

1.Download patch 120223-22 or 120222-22 from SunSolve: http://sunsolve.sun.com

2.Install the patch onto each of the HBAs in the NEM.

Follow the installation instructions included in the patch Readme file.

▼To Remove a NEM

1.Identify which NEM to replace.

If the yellow Service Action Required LED is lit, this indicates a problem with the NEM and you might choose to replace it. Otherwise, if you want to change the I/O configuration, you can choose any NEM to replace.

2.Prepare the NEM for a hot-plug procedure using either of these methods:

a.Press the Attention button on the NEM to initiate the hot-plug removal.

b.Use the ILOM web interface or the CLI to initiate the hot-plug removal.

If the NEM fails the hot-plug preparation and its Ready-to-Remove LED does not light, see the Sun Blade 8000 Series Online Help System for troubleshooting steps.

3.When the blue Ready-to-Remove LED is lit on the NEM, physically remove the NEM.
