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 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.
a. Remove all cables from the NEM.
