Replacing the FBWC module on the P410 and P411 models

CAUTION: The cache module connector does not use the industry-standard DDR3 mini-DIMM pinout. Do not use the controller with cache modules designed for other controller models, because the controller can malfunction and you can lose data. Also, do not transfer this cache module to an unsupported controller model, because you can lose data.

1.Update the controller firmware. See "Updating firmware (on page 45)."

2.Close all applications.

3.Power down the server.

4.Disconnect the power cord from the AC power source.

5.Disconnect the power cord from the server.

6.Remove or open the access panel.

7.If the existing cache module is connected to a capacitor pack, observe the FBWC module LEDs (on page 26):

o If the amber LED is flashing, data is trapped in the cache. Restore system power, and restart this procedure from step 1.

o If the amber LED is not illuminated, remove the controller from the server, and then continue with the next step.

8.Open the ejector latches on each side of the DIMM slot. Normally, the cache module is ejected from the DIMM slot. If the module is not ejected automatically, remove the cache module.

CAUTION: When connecting or disconnecting the capacitor pack cable, the connectors on the cache module and cable are susceptible to damage. Avoid excessive force and use caution to avoid damage to these connectors.
