Installing a controller module or expansion module

TIP: You can install a controller module into an enclosure that is powered on, provided you wait 60
seconds after removing the old controller module. Check controller and midplane power connectors before
inserting the new controller module into the enclosure.
See CAUTION bullets regarding "electrostatic discharge" and "anti-static protection" on
1. Loosen the thumbscrews; press the latches downward (see
2. Slide the controller module into the enclosure as far as it will go (1).
A controller module that is only partially-seated will prevent optimal performance of the controller
enclosure. Verify that the controller module is fully-seated before continuing.
3. Press the latches upward to engage the controller module (2); turn the thumbscrews clockwise until
finger-tight.
4. Reconnect the cables.
NOTE: See the web-posted 3000 Series Setup Guide for cabling information.
IMPORTANT: In a dual-controller system in which partner firmware update is enabled, when you update
firmware on one controller, the system automatically updates the partner controller.

Verifying component operation

After replacing the controller module, verify that the FRU OK LED (rear panel) illuminates green, indicating
that the controller has completed initializing, and is online/operating normally. It may take two to five
minutes for the replacement controller to become ready. If you are replacing either controller module, and
partner firmware update is enabled, you may need to wait 30 minutes to ensure that the two controllers —
with their respective ownership of the vdisks — have enough time to fully stabilize.
Use RAIDar or the CLI to perform a restart only if necessary.

Using RAIDar

1. Sign-in to RAIDar using default user manage and password !manage.
If the default user or password — or both — have been changed for security reasons, enter the secure
login credentials instead of the system defaults shown above.
