5.2.4 DIMM Module Replacement
If a DIMM module fails or a DIMM module with a higher memory capacity is required,
the onboard DIMM module must be replaced.
 DIMM module replacement: When replacing DIMM module, make sure that the
subsystem is correctly powered down and disconnect all the cables connected to the
controller prior to removing the controller module.
 Procedures on replacing the DIMM module: For complete illustrated instructions
on how to replace a DIMM module, refer to Chapter 2, Section 2.6.
5.2.5 Replacing the Controller Module
If the controller module has failed, it must be replaced. To replace a failed controller
module:
Step 1. If the subsystem has not been powered down, power down the
subsystem following the procedure listed in Chapter 4.
Step 2. Remove the BBU module (if it was installed, see Section 5.3.1), the
controller module, and then the DIMM module from the Falcon
subsystem . (See Section 5.2.4)
Step 3. Install the DIMM module and the BBU module onto the new
controller module.
Step 4. Install the new controller module into the subsystem. (See Section
2.7)
Step 5. Re-attach all the cables that were removed. These include the SCSI
cables that connect to the host or the expansion enclosures, the
Ethernet cable that was previously attached to the LAN port, and any
cables that were attached to the RS-232C audio jacks.
Step 6. Power up the system following the correct power up sequence that
will stipulated later.
