6.1 Upgrading the RAID Controller’s Cache Memory
The RAID controller is equipped with one DDR3 SDRAM socket. By default, the RAID
controller comes with at least 1GB of memory that is expandable to a maximum of 4GB. The
expansion memory module can be purchased from your dealer.
Memory Type: DDR3-1866 ECC SDRAM 240pin
Memory Size: Supports 240pin DDR3 of 1GB, 2GB or 4GB
6.1.1 Replacing the Memory Module
1. Shutdown the RAID controller using the “Shutdown Controller” function in
proRAID Manager GUI.
2. After RAID controller is shutdown, power off the switches of the 2 Power Supply
Fan Modules. Then disconnect the power cables.
3. Disconnect any Fibre cable from the controller module, and then remove the
Controller Module from the slot.
4. Remove the memory module from the RAM socket of the RAID controller by
pressing the ejector clips until the memory module pops out of the socket.
5. Align the new memory module into the socket. Make sure the notch is aligned
with the key on the socket itself. With the ejector clips in open position, press
down the memory module into the socket until it sinks into place. The ejector
clips will automatically close to lock the memory module.
6. Reinsert the Controller Module.
7. If the Disk Array has dual (redundant) RAID controllers, repeat Steps 3 to 6 to
replace/upgrade the memory of the other Controller Module.
8. Reconnect the Fibre cable(s) to the Controller Module(s). Reconnect the power
cables and power on the 2 switches of the Power Supply Fan Modules.
9. Turn on the Main Switch of the RAID Subsystem.
