Replacing a VNXe3300 Memory Module
Before you start
Before you begin the replacement procedure, make sure you have correctly identified the faulted part,
and that a replacement memory module (DIMM) is available. Refer to your EMC VNXe™ online help
Servicing your system >Adding or replacing faulted hardware components > Replace a faulted
hardware component) for instructions on how to identify failures, order new parts, and handle
hardware components. Also, prepare your disk processor enclosure (DPE) for service as described
below.
Preparing your disk processor enclosure for service
IMPORTANT
To protect your VNXe system from accidental data loss while you remove and replace DPE
components, open Unisphere™ and select Settings, then Service System.
• Log in with your service password.
•IntheSystem Components column, select the storage processor (A or B) associated with the
faulted component.
•UnderService Actions, select Enter Service Mode, then Execute service action.
The storage processor fault LED will flash alternating amber and blue while the SP remains in
Service Mode and is receiving active power.

Replacing a VNXe3300 Memory Module2
Task 1: Remove the storage processor (SP) assembly
The memory modules reside on the storage processor printed circuit board (motherboard), under the
power supply. To replace a memory module, you must remove the SP assembly from the chassis, and
then remove its power supply to gain access to processor board components.
Follow these steps to remove the storage processor assembly.
CAUTION
DO NOT REMOVE a storage processor while the “Unsafe to remove SP” LED is on.
The light indicates that you may interrupt a vital system or data-caching process.
1. Disconnect the network, power, and all other cables from the back of the assembly that includes the
faulted module. Do not remove any cables from the other storage processor assembly.
Mark the cables with the port numbers from which you removed them.
2. Locate the two orange release levers on the bottom rear of the storage processor.
3. On each lever, squeeze the latch knobs together to release the latches and then pull the latches
outward.
4. Pull out the latches until they are fully extended and the storage processor assembly is released from
its enclosure.
5. Use the latches to partially slide the assembly from its enclosure. When the storage processor is about
half-way out of its enclosure, use both hands to support the assembly and draw it fully out of the
enclosure.
6. Place the storage processor assembly on a clean, flat, static-free work area.

Task 2: Remove the power supply 3
Remove the power supply assembly from the storage processor with the faulted memory module.
Remove the power supply from the enclosure:
1. Squeeze the black and orange trigger on the back of the power supply.
2. Pull the latch towards you until it is fully extended and the power supply is released from its enclosure.
3. Slide the power supply from the storage processor assembly.

Task 2: Remove the power supply

Replacing a VNXe3300 Memory Module4
Remove the memory module from the storage processor, and install the replacement:
1. Unpack the replacement memory module and then place it on the same clean, flat, static-free work
area.
Note: Retain the packaging to return the faulted module.
2. Rotate the latches outward to release the module, then carefully pull it straight up from its socket.
3. Place the faulted module on the work area.
4. Push the replacement module straight down into the processor to firmly insert it in the socket.
5. The latches will snap to the closed position when the module is fully seated in its socket.

Replacing a VNXe3300 Memory Module6
1. Slide the power supply into the enclosure until the latch engages and begins to close.
2. Push the black knob in until the latch catches and the supply is seated and secure within the storage
processor enclosure. An audible click indicates that the latch is in place.
Note: The latch assembly includes a yellow warning marker. If the marker is visible, the latch is not fully
closed.

Task 4: Replace the power supply

Task 5: Install the storage processor assembly 7
1. Slide the storage processor assembly back into the chassis until it engages in the enclosure and the
latches start to close.
2. Push the latch knobs into the assembly to seat and secure it within the chassis. An audible click
indicates that the latches are in place.
Note: The latch assemblies include a yellow warning marker. If the marker is visible, the latch is not
fully closed.
3. Reconnect the cables to the back of the storage processor:
◆Connect all cables to the same ports from which you removed them on the faulted SP assembly.
◆Make sure you secure the power cord with the retention bails at each connector. The bails prevent
the power cord from pulling out of the connections.
The SP begins powering up immediately after connection to an active AC power source.

Task 5: Install the storage processor assembly

Task 6: Reboot the storage processor 8
Once you have replaced the faulted module and returned the storage processor assembly to the
chassis, reboot the recently serviced SP to ensure that it leaves Service Mode:
1. From Unisphere, select Settings, then Service System.
2. Log in with your service password.
3. In the System Components column, select the replaced storage processor (A or B).
4. Under Service Actions, select Reboot, then Execute service action.
Note: It may take several minutes for the system to complete its reboot and return to Normal Mode.
5. Refresh your browser, or follow the on-screen instructions, to bring the software out of Service Mode
and restore full-function Unisphere.
Verify that the new memory module is recognized by your system, and operating correctly.
1. In Unisphere, click View System Health.
2. Select the storage processor in the Component list or the graphical view.
• In the Component list, the memory module should be marked with a status OK icon:
• In the graphical view, the SP is highlighted green.
Note: If the system health monitor shows the replacement module as faulted, contact your service
provider.
Task 6: Reboot the storage processor
Task 7: Verify the operation of the new module

Task 8: Return the faulted memory module 9
Return the faulted memory module to your service provider.
1. Package the faulted part in the shipping box that contained the replacement, and seal the box.
2. From Unisphere, click Support > Need more Help? > Customer replaceable parts > Return a
customer replaceable part to enter the EMC Online Support website. The site includes detailed
instructions on how to return the faulted part.
Note: If your screen does not show the Return a customer replaceable part option, contact your
service provider for instructions on what to do next.
3. Follow the on-screen instructions. The website includes a printable return label and box pickup
information.
4. Attach the shipping label, and contact the appropriate person to pick up the faulted part.
