Replacing SDRAM DIMMs on the motherboard

About replacing SDRAM DIMMs

This section provides the supported memory configurations for your filer and the procedures for replacing the SDRAM DIMMs on the motherboard. Replacing the SDRAM DIMMs on the motherboard consists of the following procedures:

Supported memory configuration

The supported memory configuration for the F85 is 3.3V, unbuffered, 2 x 128 MB SDRAM DIMMs. The DIMMs must be in slots A and B.

Note
Only two of the four available slots for DIMMs are populated.

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.

Removing an SDRAM DIMM

To remove an SDRAM DIMM, complete the following steps.

Step	Action
1	Open the filer cover on the right side of the F85 by following Steps 1 through 11 of the procedure described in Opening the F85.
2	Remove the cooling shroud by following Steps 2 and 3 of the procedure described in Removing the cooling shroud.
3	Locate the DIMM that you want to remove.
4	Push apart the latches on either side of the DIMM to release the DIMM from its slot, as shown.
5	Pull the DIMM out of the slot.
6	Set the DIMM aside in an antistatic bag.

Installing an SDRAM DIMM

To install an SDRAM DIMM, complete the following steps.

Step	Action
1	Locate the DIMM slot for the DIMM you are installing. Note If you removed the DIMM from slot A, you must place the replacement DIMM in slot A. If you removed the DIMM from slot B, you must place the replacement DIMM in slot B.
2	Hold the DIMM by its top corners to avoid damaging the components.
3	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.
4	Push carefully, but firmly on the top edge of the DIMM until the latches snap into place.
5	Reinstall the cooling shroud. Follow the procedure in Reinstalling the cooling shroud.
