Replacing an SDRAM DIMM in a 30xx system

To replace an SDRAM DIMM in the system, you must perform the following tasks in order.

About this task

You can use this procedure with all versions of Data ONTAP supported by your system. In this procedure, a Cluster-Mode

system refers to a system running Data ONTAP 8.0 Cluster-Mode or Data ONTAP GX. A 7-Mode system refers to a system

running Data ONTAP 8.0 7-Mode or releases prior to Data ONTAP 8.0.

This procedure refers toHA pairs, which in releases prior to Data ONTAP 8.0 were called active/active confgurations and in

Data ONTAP GX were called SFO pairs.

All other components in the system must be functioning properly; if not, contact technical support.

Shutting down a node in a high-availability configurationTo shut down the node you must determine the status of the node and, if necessary, take over the node so the partner continues to

serve data from the node's storage.

Steps

1. Check the status of the target node (the node you want to perform maintenance on) by entering the following command at thesystem console of either node:

Then issue this command...If your system is confgured in...

cf status7-Mode

storage failover showCluster-Mode

2. Take one of the following actions, depending on the result of the cf status or storage failover show command:

Then...If...

Go to the next step in this procedure.Neither node is in takeover mode

The target node is in a state where you can shut it down; go to the next step in this

procedure.

The partner node took over the target node

a. Correct the problem that caused the takeover.

b. Run the cf giveback command (if in a 7-Mode system) or storage

failover giveback (if in a Cluster-Mode system) from the target node console.

c. Go back to the beginning of this procedure.

The target node took over the partner node

3. Take over the target node by entering the following command from the partner nodes console:

Then issue this command...If your system is confgured in...

cf takeover7-Mode

storage failover takeover -bynode nodeCluster-Mode

4. If you are not already grounded, properly ground yourself.

5. Turn off the power supplies and disconnect the power on the target node.

Then...If your system uses...

Unplug the power cords from the power source, and then remove the power cords.AC power

Remove the power at the DC source, and then remove the DC wires, if necessary.DC power

Shutting down the node in a stand-alone systemFor a node that is not confgured with a high-availability (HA) partner, you must perform a clean shutdown (ensuring that all data

has been written to disk) and disconnect the power supplies.

Steps

1. Enter one of the following commands from the system console:

Then issue this command...If your system is confgured as a...

halt7-Mode system

halt localCluster-Mode system

Attention: You must perform a clean system shutdown before replacing system components to avoid losing unwritten data

in the NVRAM. The NVRAM adapter has a red LED that blinks if there is unwritten data in the NVRAM. If this LED isashing red after you enter the halt command, reboot your system and try halting it again.


3. Turn off the power supplies and unplug both power cords from the power source:

Then...If your system uses...

Unplug the power cords from the power source, and then remove the power cords.AC power supplies

Remove the power at the DC source, and remove the DC wires, if necessary.DC power supplies

Opening the system

To access components inside the controller, you must open the system.

Steps


2. Unplug system cables from the motherboard tray, as needed, and keep track of where the cables were connected.

Leave the cables in the cable clips of the cable management tray so that when you reinstall the cable management tray, the

cables are already aligned.

3. Grasp the cable management tray by the side, gently push one side of the tray so that the arm slides across and off the retainingpin, and then lift off the back of the motherboard tray and set it aside.

4. Loosen the thumbscrew on the cam handle.

5. Pull the cam handle downward and slide the motherboard tray out of the system until it catches.

Attention: You do not have to remove the motherboard (as described in the following step) to replace components on the

motherboard tray. However, your system must be on a stable surface where the chassis and motherboard tray are supported

so that your system cannot tip when you pull the motherboard tray away from the chassis.

6. If you want to remove the motherboard tray, release the motherboard tray from the system by gently lifting the retaining latch

under the motherboard tray, sliding the motherboard tray all the way out of the system, and then placing the motherboard tray

on a stable, grounded surface.

If you remove the motherboard tray, make sure that you support the bottom with your free hand.

Removing the SDRAM DIMMs

To remove an SDRAM DIMM, you must locate it on the motherboard and remove it using this procedure.

Side panel

PCI card

a. Turn the motherboard tray on its side, locate the locking wing nut, and then push down and turn the locking wing nut one

quarter turn.

b. Swing the side panel away from the motherboard tray and lift the panel off the motherboard tray.

c. Remove the PCI cards, if necessary, and then lay the motherboard tray on its bottom.

3. Locate the DIMMs.

4. Note the orientation of the DIMM in the socket so that you can insert the replacement DIMM in the proper orientation.

5. Push apart the latches on either side of the DIMM to release the DIMM from its slot, and then lift it out of the slot.

Attention: Carefully hold the DIMM by the edges to avoid pressure on the components on the DIMM circuit board.

Installing the SDRAM DIMMs

To install one or more DIMMs, you must use this procedure.

Steps


2. Locate the slot where you are installing the new DIMM.

3. Remove the replacement DIMM from the antistatic shipping bag, hold the DIMM by the corners, and align it over the slot.

The notch among the pins on the DIMM should line up with the tab in the socket.

4. Insert the DIMM straight into the slot.

The DIMM fts tightly in the slot, but should go in easily. If not, realign the DIMM with the slot and reinsert it.

Attention: Visually inspect the DIMM to verify that it is evenly aligned and fully inserted into the slot. The edge connector

on the DIMM must make complete contact with the slot.

5. Push carefully, but frmly, on the top edge of the DIMM until the latches snap into place over the notches at the ends of the

DIMM.

6. Repeat the above steps to install additional DIMMs as needed.

7. Reinstall the PCI cards, if necessary, and then close and lock the side panel of the motherboard tray.

Make sure that you align the side panel with the notches in the chassis frame.

Reinstalling the motherboard tray and booting the system

After you replace a component within the motherboard tray, you must reinstall the motherboard tray in the system chassis.

Steps

1. Align the end of the motherboard tray with the opening in the chassis, if necessary, and then gently push the motherboard tray

into the system.

The cam handle begins to engage when the motherboard tray is properly seated all the way inside the system.

2. Firmly push the cam handle to fnish seating the motherboard tray in the system.

3. Tighten the thumbscrews on the cam handle.

4. Reinstall the cable management tray and recable the system, as needed.

When recabling, remember to reinstall the media converters if you are using fber cables.

5. Reconnect the power cables to the power supplies and to the power sources, and then turn on the power.

6. Reboot the system and press Ctrl-C to stop the boot process.7. Enter the following command at the boot loader prompt:

boot_diags

Running diagnostics on the DIMM

After installing a new DIMM, you should run diagnostics.

Steps

1. Enter the following command at the main diagnostics prompt to enter the memory menu:

mem

2. Confrm that the total memory output is consistent with expectations.

3. Run the Comprehensive memory tests: option 1.

4. After you complete the tests, exit diagnostics.

5. Return the system to normal operation:

Then issue this command...If your system is...

Run the cf giveback command (if in 7-mode) or storage failover giveback

(if in cluster-mode) from the partner node console.
