Replacing a Battery Backup Unit in a DiskProcessor Enclosure

Before you begin

Before you begin this maintenance activity, refer to the component handling instructions.You should also review the entire procedure prior to beginning any maintenance activityon the system.

Handling replaceable units

This section describes the precautions that you must take and the general procedures thatyoumust followwhen removing, installing, and storing any replaceable unit. The proceduresin this section apply to replaceable unit handling during hardware upgrades as well asduring general replacement.

Avoiding electrostatic discharge (ESD) damage

When replacing or installing hardware units, you can inadvertently damage the sensitiveelectronic circuits in the equipment by simply touching them. Electrostatic charge that hasaccumulated on your body discharges through the circuits.

Read and understand the following instructions:

Provide enough room to work on the equipment. Clear the work site of any unnecessary materials or materials that naturally build up

electrostatic charge, such as foampackaging, foam cups, cellophanewrappers, and similaritems.

Do not remove replacement or upgrade units from their antistatic packaging until youare ready to install them.

Gather the ESD kit and all other materials before servicing any units. After servicing begins, avoid moving away from the work site; otherwise, you might

build up an electrostatic charge. Use the ESD kit when handling any units.

Replacing a BBU in a DPE 3

If an emergency arises and the ESD kit is not available, follow the procedures inEmergency procedures (without an ESD kit) on page 4

Use the ESD wristband that is supplied with the server. To use it, attach the clip of the ESD wristband (strap) to any bare (unpainted) metal on

the cabinet or enclosure, and then put the wristband around your wrist with the metalbutton against your skin.

Emergency procedures (without an ESD kit)

In an emergency when an ESD kit is not available, use the following procedures to reducethe possibility of an electrostatic discharge by ensuring that your body and the subassemblyare at the same electrostatic potential.

These procedures are not a substitute for the use of an ESD kit. Follow them only inthe event of an emergency.

Before touching any unit, touch a bare (unpainted) metal surface of the enclosure. Before removing any unit from its antistatic bag, place one hand firmly on a bare metal

surface of the enclosure, and at the same time, pick up the unit while it is still sealed inthe antistatic bag. Once you have done this, do not move around the room or touch otherfurnishings, personnel, or surfaces until you have installed the unit

When you remove a unit from the antistatic bag, avoid touching any electroniccomponents and circuits on it.

If you must move around the room or touch other surfaces before installing a unit, firstplace the unit back in the antistatic bag. When you are ready again to install the unit,repeat these procedures.

Removing, installing, or storing CRUs

Use the following precautions when removing, handling, or storing CRUs:

Do not remove a faulty CRU from the cabinet until you have the replacement available. Handle a CRU only when wearing an ESD wristband (strap).

Attach the clip of the ESD wristband to the ESD bracket or bare metal on a cabinetenclosure.

Wrap the ESD wristband around your wrist with the metal button against your skin.

Handle a CRU gently. A sudden jar, drop, or vibration can permanently damage someCRUs.

Never use excessive force to remove or install a CRU. Take time to read the instructionscarefully.

4 Replacing a BBU in a DPE

Before you begin

For a module that must be installed into a slot in an enclosure, examine the rearconnectors on the module for any damage before attempting its installation.

Store a CRU in the antistatic bag and the specially designed shipping container in whichyou received it. Use the antistatic bag and special shipping container when you need toreturn the CRU.

A sudden jar, drop, or even a moderate vibration can permanently damage somesensitive FRUs.

Some CRUs have the majority of their weight in the rear of the component. Ensurethat the back end of the CRU is supported while installing or removing it. Droppinga CRU could result in personal injury or damage to the equipment.

Summary of tasks for replacing a BBU

To replace a BBU you must complete the tasks below in the order in which they appear.This document provides instructions for completing each task.

1. Identify the faulted BBU.

2. Remove the faulted BBU from the base module.

Before you begin

Preparing the system

Take the following actions to prepare the system for this maintenance activity.

Disabling call home

Use Unisphere or naviseccli to disable call home for the storage system during thismaintenance activity. You can disable call home responses for a user determined time periodbetween the 30 minute minimum and the 240 minute maximum.

Note: The procedure below details how to disable call home using Unisphere. As an alternative youcan use naviseccli on a Windows management client to disable call home:

naviseccli eventmonitor -monitor -disableresponse -user -password -scope 0 -server -time

1. Log in to the storage system or the Unisphere domain that contains the storage system.

2. From Unisphere, select System Monitoring and Alerts Notification and select theDistributed Monitors tab.

3. Right click on the name of SP A in the list of distributed monitors for the storage systemon which you are disabling call home and select Disable/Enable Responses.

The Disable/Enable Responses dialog box appears.

4. Select the Disable Responses check box and set a time period during which responseswill be disabled for the anticipated maintenance activity. Then click OK.

In the popup that appears, click Yes to confirm.

5. Repeat these steps for SP B.


Important: YouMUST disable responses on BOTH SP A and SP B to disable the storage system callhome responses.

The storage systemwill not call home or respond to any other template applied to the storagesystem for the specified time period.

Note: Disable/Enable Responses (quiet mode) feature will automatically re-enable call homewhen thetimer you set to disable call home expires. Network connectivity between the storage system and thecall home monitoring station is required for the Software Assistant to automatically enable call homeand verify the call home rules.

Checking the system for faulted hardware

Follow the steps below to verify the status of the system's hardware components.

Diagnosing faulted storage system hardware components

Use this procedure to log in to EMC Unisphere and check for any faulted hardwarecomponents in the storage system.

1. Start Unisphere for the storage system by entering the storage processor IP address in abrowser window.

2. In the system drop-down list on the menu bar, select the system in which you may havea faulted hardware component.

3. Select System Hardware Storage Hardware.

4. Check for any faulted storage hardware components.

Locate the faulted battery backup unit

Follow these steps to locate the faulted battery backup unit:
