EMC VNXe3100 User manual

This document describes how to replace a faulted input/output (I/O) module in a
VNXe3100 or VNXe3150 disk processor enclosure (DPE). For information on upgrading the
existing I/O modules in a VNXe3100 or VNXe3150 DPE with a different type of I/O module,
refer to the document for upgrading I/O modules in a VNXe3100 or VNXe3150 system.
Before you start
Before you begin the procedure, 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.

Tasks to replace an I/O module
Task 1: Preparing the storage processor (SP) for service
IMPORTANT
To protect your VNXe system form accidental data loss while you replace an I/O module in
an SP, you must prepare the SP for service before you replace the I/O module. You prepare
an SP for service by putting it in Service mode.
1. Open Unisphere™ and select Settings, then Service System.
2. Log in with your service password.
3. In the System Components column, select the storage processor (SP A or SP B)
associated with the faulted component.
4. Under Service Actions, select Enter Service Mode, then Execute service action.
5. In the Service Confirmation dialog box click OK.
Putting an SP into Service mode takes about 10 minutes to complete. The storage
processor fault LED will flash alternating amber and blue while the SP remains in
Service mode and is receiving active power.
6. Wait until the SP fault LED is flashing alternating amber and blue before continuing to
the next task.

Task 2: Remove the SP assembly
The I/O module resides on the SP printed circuit board (motherboard). To replace a
module, you must remove the SP assembly from the chassis, and then remove its cover to
gain access to processor board components.
Follow these steps to remove the SP assembly:

DO NOT REMOVE an SP while the “Unsafe to remove SP” LED is on. The light
indicates that you may interrupt a vital system or data-caching process.
If your system has a single SP, DO NOT REMOVE the storage processor if the “Unsafe to
remove” LED for the cache protection module is on.
1. Disconnect the network and all other cables from the back of the assembly that will
include the new I/O module.
Do not remove any cables from the other SP assembly.
Mark the cables with the port numbers from which you removed them.

The SP assembly comes completely out of the chassis. In addition to holding the
latches, be prepared to support the assembly to avoid dropping it.
2. Locate the left and right latches.
3. Pinch the orange tabs and pull the latches to the sides to eject the SP assembly from
the chassis.
4. Pull the SP assembly straight out of the chassis and place it on a static-free surface.

Task 4: Remove the faulted I/O module
1. Lift the blue latch carefully until it ejects the I/O module from the connector.
2. Lift the module out and away from the canister and place it on a static free surface.

Task 5: Install the replacement I/O module
Before you start
Unpack the replacement I/O module and then place it on a flat, static free work area.
Retain the packaging to return the faulted I/O module.
Procedure
1. Angle the I/O module slightly so it fits into the canister and align it with the blue
alignment pins.

Do not attempt to seat the I/O module into the CPU connector while you are holding
the I/O module at an angle. Doing so will damage the connections. The I/O module
should be flat before you attempt to seat the connector.
2. With the module aligned and parallel to the CPU board, press the latch down to fully
seat the module in the connector.
3. Push down on the force point indicated on the I/O module to ensure that the module
is completely seated on the processor board.

Task 6: Replace the SP top cover
1. Align the cover tabs with the notches in the canister.
2. Slide it forward 1/4 inch until the tab secures the cover.
Task 7: Install the SP assembly
1. Pull out the latches on each side of the SP assembly and make sure they stay in the
open position.
2. Align the SP assembly with the chassis opening and push it straight into the chassis.
The latches begin to close when they contact the chassis edges.
3. Close the right and left latches to fully seat the SP assembly in the chassis.
An audible click indicates that the latches are secure.
4. Reconnect the cables to the back of the SP assembly being sure to connect all cables
to the same ports from which you removed them on the faulted SP assembly.
The SP begins powering up immediately after connection to an active AC power
source.

Tasks to replace an I/O module
Task 8: Reboot the storage processor
Once you have replace the faulted I/O module and returned the SP 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 serviced SP (SP A or SP B).
4. Under Service Actions, select Reboot, then Execute service action.
It may take up to 12 minutes for the system to complete its reboot to return to Normal
mode and restart the servers.
5. Refresh your browser, or follow the on-screen instructions, to bring the software out of
Service mode and restore full-function Unisphere.
Task 9: Verify the operation of the replacement I/O module
Verify that the replacement I/O module is recognized by your system, and operating
correctly:
1. In Unisphere™, select System, then System Health.
2. Select the SP in the Component list or the graphical view:
• In the Component list, the new module should be marked with a status OK icon:
• In the graphical view, the module should be highlighted green.
If the system health monitor shows the module as faulted, contact your service
provider.
Task 10: Return the faulted I/O module
1. Package the faulted I/O module in the shipping box that contained the replacement
I/O module, 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 faulted parts.
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 parts.
