AX100-Series

Adding a Disk Module

Revision A02

November 22, 2004

Configuration Rules and Recommendations

The following rules and recommendations apply to all AX100-Series

systems.

◆If possible, all drives in an AX100-Series enclosure should have

the same speed and capacity.

◆All disks in a disk pool should have the same capacity. Since all

disks in a pool are bound to match the smallest capacity disk, you

will waste disk space if the disks do not have the same capacity.

◆All disks in a disk pool should have the same speed.

◆You cannot use disk modules in slots 0-3 as hot spares. You can

configure a hot spare in any other slot; AX100-Series enclosures

allow unused slots (with filler modules) between drives.

For additional information about disk pools and other disk

configuration topics, refer to the appropriate Planning Your

AX100-Series Storage System Configuration description on the

AX100-Series support website.

Adding a Disk Module

Handling FRUs

This section describes the precautions that you must take and the

general procedures you must follow when removing, installing, and

storing disk drive modules or any other Field Replaceable Unit

(FRU).

Power Issues and

FRUs AX100-Series storage systems are designed to be powered up

continually. Disks and power supplies are hot repairable; that is, you

can replace faulty units while the system is running. Front bezels

should always be attached and each compartment should contain a

FRU or filler panel to ensure EMI compliance and proper air flow

over the FRUs.

You should not remove a faulty FRU until you have a replacement

available.

When you replace or install FRUs, you can inadvertently damage the

sensitive electronic circuits in the equipment by simply touching

them. Electrostatic charge that has accumulated on your body

discharges through the circuits. If the air in the work area is very dry,

running a humidifier in the work area will help decrease the risk of

ESD damage. Follow the procedures below to prevent damage to the

equipment.

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 foam packaging, foam cups,

cellophane wrappers, and similar items.

◆Do not remove replacement or upgrade FRUs from their antistatic

packaging until you are ready to install them.

◆Before you service a storage system, gather together the ESD kit

and all other materials you will need. Once servicing begins,

avoid moving away from the work site; otherwise, you may build

up an electrostatic charge.

◆An ESD wristband is supplied with your storage system. To use

it, attach the clip of the ESD wristband (strap) to any bare

(unpainted) metal on the storage system; then put the wristband

around your wrist with the metal button against your skin.

Handling FRUs

◆Use the ESD kit when handling any FRU. If an emergency arises

and the ESD kit is not available, follow the procedures in the

Emergency Procedures (Without an ESD Kit) section.

Emergency

Procedures (Without

an ESD Kit)

In an emergency when an ESD kit is not available, use the following

procedures to reduce the possibility of an electrostatic discharge by

ensuring that your body and the subassembly are at the same

electrostatic potential.

These procedures are not a substitute for the use of an ESD kit.

Follow them only in the event of an emergency.

◆Before touching any FRU, touch a bare (unpainted) metal surface

of the cabinet or storage system.

◆Before removing any FRU from its antistatic bag, place one hand

firmly on a bare metal surface of the storage system, and at the

same time, pick up the FRU while it is still sealed in the antistatic

bag. Once you have done this, do not move around the room or

touch other furnishings, personnel, or surfaces until you have

installed the FRU.

◆When you remove a FRU from the antistatic bag, avoid touching

any electronic components and circuits on it.

◆If you must move around the room or touch other surfaces before

installing a FRU, first place the FRU back in the antistatic bag.

When you are ready again to install the FRU, repeat these

procedures.

Adding a Disk Module

CAUTION

Disk modules are extremely sensitive electronic components.

Always handle a disk module gently, and observe the following

guidelines:

◆Whenever possible or practical, replace a disk module with

another of the same model. Refer to the AX100 support website

or contact your sales/service representative for a list of

approved disk replacements.

◆Follow the instructions in the preceding section, Handling

FRUs.

◆Disk modules are sensitive to the extreme temperatures

sometimes encountered during shipping. We recommend that

you leave new disk modules in their shipping material, and

expose the package to ambient temperature for at least four

hours before attempting to use the new modules in your

system.

◆Always wear a properly attached ESD wristband when

removing or replacing a disk module.

◆When removing a disk module, pull the module partially out of

the slot, then wait 30 seconds for the drive to spin down before

removing it.

◆Place modules on a soft, antistatic surface, such as an

industry-standard antistatic foam pad or the container used to

ship the module. Never place a disk module directly on a hard

surface.

◆Never hit modules, stack modules, or allow them to tip over or

fall.

◆Avoid touching any exposed electronic components and circuits

on the disk module.

◆Do not remove a faulty disk module until you have a replacement

module (with the same or an approved part number) or a filler

module available. The part number (PN005xxxxxx) appears on

the front of the module.

You must remove the storage system’s front bezel to gain access to

the disk modules. The bezel is required for EMI compliance when the

storage system is powered up. Remove it only to replace or add a

disk module.

Adding a Disk Module

Unlocking and Removing the Front Bezel

Follow these steps to remove the front bezel and gain access to the

disk modules. Refer to Figure 1.

1. Insert the key that shipped with your storage system into the

bezel lock, and turn it to release the lock.

2. Press the two latch buttons on the bezel surface toward each other

to release the bezel from the cabinet.

3. Pull the bezel off the cabinet and put it on a clean, static-free

surface.

Removing a Disk Filler Module

Locate the slot where you want to install the disk module, and

remove the filler module, as shown in Figure 2.

Figure 2 Removing a Disk Filler Module

Installing a Disk Module

1. Make sure an ESD wristband is attached to your wrist and the

storage system (see the precautions on Page 3).

2. Align the module with the guides in the slot.

3. Gently push the module completely into the slot. To ensure that

the module seats completely, push in on the disk label as you

engage the latch. See Figure 3.

4. Use Navisphere® Express to verify that the new disk is

operational.

a. From a network-connected station, start Navisphere® Express

for the AX100-Series storage system by entering the IP address

in a browser window. (Refer to the release notes on the AX100

support website for a list of supported browsers.)

b. In the navigation pane, under View, click components.

c. Scan the list of components to verify that the new disk is

Normal; that is, recognized and working properly.

5. Remove and store the ESD wristband and continue to the next

section to install the front bezel.

Installing and Locking the Front Bezel

Refer to Figure 4 as you do the following:

1. Align the bezel with the storage system.

2. Gently push the bezel into place on the cabinet until it latches.

support website or the documentation CD for configuration and

planning guidance, and to the Navisphere Express online help for

detailed information.
