Replacing the SDRAM DIMM on the CPU module

About replacing SDRAM DIMMs

The SDRAM DIMM is on the CPU module motherboard. You must remove the CPU module from the chassis before replacing the DIMM.

Required memory configuration

The FAS270/270c supports 1 x 1 GB, 2.5V 184P DDR SDRAM DIMM. The DIMM slot is inside the CPU module.

Caution
All DIMMs must be listed on the Network Appliance Approved Parts List. Contact Network Appliance Sales to obtain this list. Unapproved DIMMs have not been tested for reliability and might cause system downtime.

Replacing the SDRAM DIMM

To remove the SDRAM DIMM, complete the following steps.

Step	Action
1	Perform a clean system shutdown before removing the DIMM. Caution Removing the DIMM without first performing a clean system shutdown can result in data loss.
2	Remove the CPU module containing the DIMM to be replaced. Follow the procedure in Removing the CPU module.
3	Put on the antistatic wrist strap and grounding leash.
4	Unplug the battery pack from the motherboard before removing the DIMM. For the location of the battery pack and cable connection, see the illustration in Step 4 of Replacing the battery.
5	Push apart the latches on either side of the DIMM to release the DIMM from its slot, as shown.
6	Pull the DIMM out of the slot.
7	Set the old DIMM aside in an antistatic bag.
8	Pick up the new DIMM by its top corners to avoid damaging the components.
9	Insert the DIMM straight into the slot. The DIMM fits tightly in the slot, but should go in easily. If not, realign the DIMM with the slot and try again. Caution Visually inspect the DIMM to verify that it is evenly aligned and fully inserted into the slot; otherwise, the edge connector on the DIMM does not make complete contact with the slot.
10	Push carefully but firmly on the top edge of the DIMM until the latches snap into place.
11	Plug the battery cable back into the motherboard.
12	Reinstall the CPU module. See Procedures for installing the CPU module.
13	After turning on your system, run diagnostics on the SDRAM DIMM. See the Diagnostics Guide for more information.
