Replacing The Controller Module - Rorke Data Galaxy 16i User Manual

3. Re-insert the new DIMM module. If you are using a
redundant controller module the new DIMM module MUST
HAVE the same capacity and operate at the same speed as
the DIMM module that is already installed on the operating
controller board.
4. Once the new DIMM module has been installed, replace the
optional BBU module (see Section 5.2.2) and the controller
module (see section 2.7).

5.2.4 Replacing the Controller Module

If the controller module itself has failed, it must be replaced. To
replace a failed controller module:
1. Remove the controller module from the Galaxy 16i
subsystem (see Section 5.2.1), the BBU module (see Section
5.2.2) (if it was installed) and the DIMM module (see Section
5.2.3).
2. After these three items have been removed, install the DIMM
module and the optional BBU module onto the new
controller module.
6. Once the DIMM module and the optional BBU module have
been installed on the new controller module, install the new
controller module into the Galaxy 16i subsystem (see
Section 2.7).
7. Re-attach all the cables that were removed. These include
the cables that are used to connect to the host, FC cables that
must be connected to the expansion port (redundant models
only), any ethernet cable that was previously attached to the
LAN port and any cables that were attached to the RS-232C
audio jacks.
8. If you are using a single controller module power up the
system.
