Rack safety

Rack installation

DANGER

Observe

the following precautions when working on or

around your IT rack system:

v Heavy equipment - personal injury or equipment damage

might result if mishandled.

v Always lower the leveling pads on the rack cabinet.

v Always install stabilizer brackets on the rack cabinet.

v To avoid hazardous conditions due to uneven mechanical

loading, always install the heaviest devices in the bottom of the rack cabinet. Always install servers and optional devices starting from the bottom of the rack cabinet.

v Rack-mounted devices are not to be used as shelves or work

spaces. Do not place objects on top of rack-mounted devices.

viii

v Each rack cabinet might have more than one power cord. Be

sure to disconnect all power cords in the rack cabinet when directed to disconnect power during servicing.

v Connect all devices installed in a rack cabinet to power

devices installed in the same rack cabinet. Do not plug a power cord from a device installed in one rack cabinet into a power device installed in a different rack cabinet.

v An electrical outlet that is not correctly wired could place

hazardous voltage on the metal parts of the system or the devices that attach to the system. It is the responsibility of the customer to ensure that the outlet is correctly wired and grounded to prevent an electrical shock.

(R001 part 1 of 2

CAUTION:

v Do not install a unit in a rack where the internal rack ambient

temperatures will exceed the manufacturer’s recommended ambient temperature for all your rack-mounted devices.

v Do not install a unit in a rack where the air flow is compromised. Ensure

that air flow is not blocked or reduced on any side, front, or back of a unit used for air flow through the unit.

v Consideration should be given to the connection of the equipment to the

supply circuit so that overloading of the circuits does not compromise the supply wiring or overcurrent protection. To provide the correct power connection to a rack, refer to the rating labels located on the equipment in the rack to determine the total power requirement of the supply circuit.

v (For sliding drawers.) Do not pull out or install any drawer or feature if the

rack stabilizer brackets are not attached to the rack. Do not pull out more than one drawer at a time. The rack might become unstable if you pull out more than one drawer at a time.

v (For fixed drawers) This drawer is a fixed drawer and should not be moved

for servicing unless specified by manufacturer. Attempting to move the drawer partially or completely out of the rack may cause the rack to become unstable or cause the drawer to fall out of the rack.

CAUTION: Removing components from the upper positions in the rack cabinet improves rack stability during relocation. Follow these general guidelines whenever you relocate a populated rack cabinet within a room or building:

v Reduce the weight of the rack cabinet by removing equipment starting at

the top of the rack cabinet. When possible, restore the rack cabinet to the configuration of the rack cabinet as you received it. If this configuration is not known, you must do the following:

– Remove all devices in the 32U position and above.

– Ensure that the heaviest devices are installed in the bottom of the rack

cabinet.

– Ensure that there are no empty U-levels between devices installed in

the rack cabinet below the 32U level.

– If the rack cabinet you are relocating is part of a suite of rack cabinets,

detach the rack cabinet from the suite.

– Inspect the route that you plan to take when moving the rack to

eliminate potential hazards.

– Verify that the route that you choose can support the weight of the

loaded rack cabinet. Refer to the documentation that came with your rack cabinet for the weight of a loaded rack cabinet.

– Verify that all door openings are at least 760 x 2030 mm (30 x 80 in.).

– Ensure that all devices, shelves, drawers, doors, and cables are secure.

– Ensure that the four leveling pads are raised to their highest position.

– Ensure that there is no stabilizer bracket installed on the rack cabinet

during movement.

– Do not use a ramp inclined at more than ten degrees.

– Once the rack cabinet is in the new location, do the following:

- Lower the four leveling pads.

- Install stabilizer brackets on the rack cabinet.

- If you removed any devices from the rack cabinet, repopulate the rack cabinet from the lowest position to the highest position.

If a long distance relocation is required, restore the rack cabinet to the

–

configuration of the rack cabinet as you received it. Pack the rack cabinet in the original packaging material, or equivalent. Also, lower the leveling pads to raise the casters off of the pallet and bolt the rack cabinet to the pallet.

Chapter 1. Preparing for the installation

This chapter describes the preparation requirements for first-time installation of the IBM EXN1000 Storage Expansion Unit (model number 2861-001).

This chapter discusses the following topics:

v “Required manuals, tools and equipment” v “Handling static-sensitive devices” v “Planning and organizing the installation” on page 2 v “Before you begin your installation” on page 7

Required manuals, tools and equipment

In addition to this document, you need the following manuals:

v Installation and Setup Instructions for your storage system

v EXN1000 Installation and Setup Instructions v Hardware and Service Guide for your storage system

Required tools and equipment for installation

You must supply the following tools and equipment:

v Ethernet LAN cables v Fibre Channel cables v Console (for example, a PC or laptop) v #2 Phillips screwdriver and slotted screwdriver v Pointed tool for setting switches v 7-mm nut driver v Antistatic ESD strap and grounding leash

Handling static-sensitive devices

Attention: The EXN1000 expansion unit uses electronic components that are sensitive to static electricity. Static discharge from your clothing or other fixtures around you can damage these components. Put on an antistatic ESD strap and grounding leash to free yourself of static electricity before touching any electronic components.

Attention: Static electricity can damage electronic devices and your system.

To avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them.

To reduce the possibility of electrostatic discharge (ESD), observe the following precautions:

v Limit your movement. Movement can cause static electricity to build up

around you.

v Handle the device carefully, holding it by its edges or its frame. v Do not touch solder joints, pins, or exposed printed circuitry. v Do not leave the device where others can handle and possibly damage the

device.

v While the device is still in its static-protective package, touch it to an

unpainted metal part of the system unit for at least two seconds. This drains static electricity from the package and from your body.

v Remove the device from its package and install it directly into your system

unit without setting it down. If it is necessary to set the device down, place it in its static-protective package. Do not place the device on your system unit cover or on a metal table. Take additional care when handling devices during cold weather because heating reduces indoor humidity and increases static electricity.

installation.

Before you begin your installation

Before you install one or more EXN1000 expansion units in a rack, you need to understand the following information:

v EXN1000 expansion unit numbering v Drive addressing v Speed setting v Supported disk drives v Drive bay requirements

Chapter 1. Preparing for the installation 7

Attention: Verify that all shelf IDs are correct and sequential in the individual loop(s). If this system was configured by manufacturing, there are labels on the outside of the packaging carton and on the side of the expansion unit chassis to indicate which loop on which node (Filer 1 or 2) that shelf should be located. Make certain the expansion units are placed and cabled according to these labels. The filer nodes may also have a label on the packaging carton and chassis side to clearly distinguish the nodes (Filer 1 and Filer 2).

EXN1000 expansion unit numbering

Each EXN1000 expansion unit in a loop must have a unique ID. A valid shelf ID is from 1 through 7. ID 1 is used for the first EXN1000 in a new loop, or if the filer also contains disks, then ID 2 is used for the EXN1000 closest to the N series storage system controller (which uses ID 1). Shelf IDs for additional expansion units are incremented sequentially from the number of the first expansion unit (either 1 or 2).

Each EXN1000 expansion unit shipped with an N series storage system has its assigned ID already set on its back panel and has a shelf ID label already placed on its front bezel.

You must ensure that the EXN1000 expansion unit has the correct shelf ID number on the label. If you change the shelf ID of the expansion unit by changing the ID switch at the rear of the unit, replace the shelf ID label to match the new shelf ID for the unit.

Note: Additional shelf ID labels are supplied with your unit.

The shelf ID label is on the right side of the unit, as shown in the following illustration.

Shelf 1

Drive Bays

013

Loop ID

29 - 16

Figure 1. Shelf ID label

8910111213 3 2 1 0

IBM sets the disk shelf IDs at the factory on configured systems, using an ID switch on the back panel. If you order additional EXN1000 expansion units, you must set the disk shelf ID and apply the correct labels provided with the EXN1000.

Note: If you enter a shelf ID that is not from 1 through 7, the drive addresses

default to those of a shelf with the ID switch set to 7 even though the Shelf ID indicator in the front operation panel displays a dash (-).

The example in the following illustration shows an EXN1000 expansion unit with the disk shelf ID set to 2.

Figure 2. EXN1000 shelf ID

Drive addressing

In addition to identifying the disk shelf ID and the direction of the drive bays, the ID label on the right side of the EXN1000 expansion unit includes the drive address. The drive address identifies the disks in the EXN1000 expansion unit. The last sheet of the quick reference cards that come with your EXN1000 expansion unit shows the seven disk shelf IDs and their corresponding drive addresses.

Speed setting

Make sure that all expansion unit speed switches are set to the correct position for your application.

v If connecting to an N3700 storage system, the speed switch must be set to

the 1Gb position.

v If connecting to any other N series storage system, the speed switch must

be set to the 2Gb position.

The speed setting switch is located on the circuit board inside the

Note:

AT-FCX module. In order to set or adjust the speed setting, you must remove the AT-FCX module. See “Replacing an AT-FCX module” on page 35.

The speed setting must be set before you power on the expansion unit.

Figure 4. EXN1000 speed setting switch

Supported disk drives

For the types of disks the EXN1000 expansion unit supports, visit the following Web site:

www.ibm.com/storage/nas/

Note: You should not mix different drive types in the same expansion unit.

Drive bay requirements

For enclosure services monitoring to work, drive bays 0 and 1 must contain a disk. In addition, the EXN1000 expansion unit must be populated with at least 5 hard disk drives to ensure proper operation.

Attention: All drive bays in the expansion must contain either a hard disk drive or a drive blank cover to maintain proper air flow and cooling.

The 14 drive bays in the EXN1000 expansion unit are numbered 0 through 13 from right to left, as shown in Figure 1 on page 8. Hard disk drives should be populated in adjacent drive bays in the expansion unit in this sequence, beginning with drive bay 0.

The N series storage system uses the enclosure services monitoring method to monitor environmental conditions of the EXN1000 expansion unit. Enclosure services conditions are communicated to the N series storage system through the AT-FCX module.

The following table describes the three stages of enclosure services monitoring.

Chapter 1. Preparing for the installation 11

Table 4. Stages of enclosure services monitoring

Stage Device What it does...

1 N series storage system Uses a subset of SCSI-3

commands to monitor the EXN1000 expansion unit for data related to disk presence, temperature, power supply units, and fan status.

2 N series storage system Sends the commands

through its Fibre Channel interface to the AT-FCX I/O module on the EXN1000 expansion unit.

3 AT-FCX module Collects the requested data

and sends it to the storage appliance.

Chapter 2. Connecting an EXN1000 expansion unit

This chapter describes how to connect a single EXN1000 expansion unit or a loop of EXN1000 expansion units to a supported N series storage system or to other expansion units. This chapter also describes how to ground your system and how to connect your system to power.

This chapter discusses the following topics:

v “Handling fiber-optic cables” v “Connecting EXN1000 expansion units” on page 14 v “Grounding EXN1000 expansion units” on page 15 v “Connecting the EXN1000 expansion unit to a power source” on page 15 v “Hot-adding an EXN1000 expansion unit to an existing loop” on page 15

Handling fiber-optic cables

Before you use fiber-optic cables, read the following precautions.

Attention: To avoid damage to the fiber-optic cables, follow these guidelines:

v Do not route the cable along a folding cable-management arm. v When attaching to a device on slide rails, leave enough slack in the cable so

that it does not bend to a radius of less than 38 mm (1.5 in.) when extended or become pinched when retracted.

v Route the cable away from places where it can be snagged by other devices

in the rack cabinet.

v Do not overtighten the cable straps or bend the cables to a radius of less

than 38 mm (1.5 in.).

v Do not put excess weight on the cable at the connection point. Be sure that

the cable is well supported.

Connecting EXN1000 expansion units

This section describes the requirements for connecting the EXN1000 expansion unit to N series storage systems and other expansion units. For detailed instructions about how to install and connect one or more EXN1000 expansion units in a rack, refer to the Installation and Setup Instructions.

v IBM strongly recommends using optical (fibre channel) cabling whenever

possible.

v Refer to the IBM System Storage N series Introduction and Planning Guide for

details about the maximum number of drive loops, maximum number of expansion units or hard disk drives per loop, maximum total storage capacity, and maximum total number of hard disk drives for configurations using your N series storage system. (For example, you can connect a maximum of one loop of three fully populated expansion units to an N3700.)

v Multipath looping is recommended for all configurations to provide

additional redundancy. This includes single or dual controller and single or multiple EXN1000 expansion units.

v Do not mix Fibre Channel EXN2000 or EXN4000 and SATA EXN1000

expansion units in the same loop.

EXN1000 expansion unit cabling requirements

You must meet the cabling requirements discussed in the following sections when connecting the EXN1000 AT-FCX module to an N series storage system or to other expansion units.

For the latest information on cabling requirements, see the Installation and Setup Instructions and the Hardware and Service Guide for your storage system.

Connecting the expansion unit directly to the N series storage system

When connecting the EXN1000 to an N series storage system, you must use appropriate cables and connectors according to the following guidelines:

v For direct connections to N3700 storage systems with system serial

numbers between 13-00032 and 13-01000 (in general, these are N3700 systems shipped prior to January 31, 2006): Use a NAS-to-EXP fibre

channel copper cable (#2020 or 2022). For attachment to an N3700 Model A10, one NAS-to-EXP fibre channel copper cable is required. For attachment to an N3700 Model A20, two NAS-to-EXP fibre channel copper cables are required.

v For direct connections to N3700 storage systems with system serial

numbers 13-01001 or higher (in general, these are N3700 systems shipped after January 31, 2006): Use an LC-to-LC fibre channel optical cable and 2

SFPs for attachment to an N3700 Model A10. Use 2 LC-to-LC fibre channel optical cables and 4 SFPs for attachment to an N3700 Model A20.

v For direct connections to all other N series storage systems: Use an

LC-to-LC fibre channel optical cable and one SFP.

Connecting

the expansion unit to other expansion units

When connecting the EXN1000 to other expansion units, IBM strongly recommends using LC-to-LC fibre channel optical cables. You must use 2 SFPs per LC-to-LC fibre channel optical cable.

Note: SFP-to-SFP fibre channel copper cables may also be used for

connections (to a maximum of three meters) between expansion units.

Grounding EXN1000 expansion units

For proper grounding, you must daisy-chain the EXN1000 expansion units together with the provided braided copper cables and screws. If possible, you should ground the N series storage system to the EXN1000.

Each EXN1000 expansion unit is shipped with a 0.25m (~6 inch) braided copper cable and an M5 x 0.5 inch Phillips head screw. The copper cable has a hole on each end for grounding shelf-to-shelf.

For detailed instructions about how to ground connected EXN1000 expansion units in a rack, refer to the Installation and Setup Instructions for your storage system.

Connecting the EXN1000 expansion unit to a power source

The EXN1000 expansion unit is shipped with two power supplies, installed in bay PSU1 and bay PSU2, respectively, and an AC power cord for each power supply. You must have separate circuit breakers for each power supply.

For detailed instructions about how to connect EXN1000 expansion units to a power source, refer to the EXN1000 Installation and Setup Instructions.

Hot-adding an EXN1000 expansion unit to an existing loop

This section provides information about how to hot-add an EXN1000 expansion unit to an existing loop. It also tabulates the error messages that appear on your N series storage system console if the attempt at hot-adding was unsuccessful.

Note: The hot-added EXN1000 expansion unit must have new drives that will

be used as spares only.

Chapter 2. Connecting an EXN1000 expansion unit 15

Attention: It is recommended that you stop all I/O processes before hot-adding an EXN1000 to an existing loop. Perform a hot-add only during off-peak times.

To hot-add an EXN1000 expansion unit to an existing loop, complete the following steps:

1. Put on the antistatic ESD strap and grounding leash.

2. Verify that you received the disk shelf ID labels.

3. Install the new EXN1000 expansion unit in the rack, cable and ground the

EXN1000, and connect the power cables to the EXN1000, as described in the Installation and Setup Instructions you received with your N series product.

CAUTION:

Do not turn on the power to the EXN1000 expansion unit yet.

After you have completed the installation steps described in the Installation and Setup Instructions, continue with Step 4.

4. Verify that all the cables are securely fastened.

CAUTION:

Poorly secured cables cause the N series storage system to panic over an open loop.

5. If you have not done so, give the EXN1000 expansion unit a unique disk shelf ID. It is recommended that you choose a number which is one higher than the previous shelf (or ID 1 if this is the first EXN1000 in the loop).

a. Press the small buttons on the switch on the rear of the EXN1000

expansion unit, using the + button to raise the number and the button to lower the number to a valid ID from 1 through 7. Refer to Figure 2 on page 9 for an illustration.

Only use disk shelf ID 7 if it is the last ID available. If you

Note:

change a disk shelf ID, you must power-cycle the EXN1000 expansion unit for the new ID to take effect. The disk shelf ID display on the front of the EXN1000 expansion unit blinks until you power-cycle the EXN1000 expansion unit.

b. Verify that the disk shelf ID is not being used in the loop by entering

the following command at the console:

fcstat device_map adaptername

c. Select the correct matching shelf ID label, reference Figure 1 on page 8,

and attach it to the right flange of the new EXN1000 expansion unit.

CAUTION:

An invalid disk shelf ID causes the N series storage system to panic.

6. Turn on the power to the EXN1000 expansion unit. Yo u must wait 30 seconds for the shelf electronics to finish initializing.

7. In 60 seconds, the N series storage system recognizes the hot-added EXN1000 expansion unit.

Error messages

The following error messages appear on your N series storage system console if your attempt at hot-adding the EXN1000 expansion unit is unsuccessful.

Table 5. N series storage system console error messages

Error message Explanation

Open loop panic One of two reasons cause this error message to appear:

v The shelf-to-shelf cable between the now second-to-last unit

and the newly added EXN1000 expansion unit is defective or is not securely fastened.

v The speed of the newly added EXN1000 expansion unit is

incorrectly set.

Soft address panic

One of two reasons cause this error message to appear:

v There is an invalid disk shelf ID. v The power was turned on before the disk shelf ID was

changed and the EXN1000 expansion unit was not power-cycled after the disk shelf ID was changed.

v “Removing a power supply” on page 34 v “Installing a power supply” on page 35

Chapter 4. Replacing EXN1000 expansion unit devices 33

Rules for replacing power supplies

When replacing a power supply on your EXN1000 expansion unit, observe the following rules:

v Yo u do not need to turn off the power to the expansion unit when you

replace one power supply, only the power supply that is being replaced.

v If you are replacing both power supplies in the same EXN1000 expansion

unit, replace them one at a time to avoid powering down the EXN1000 expansion unit.

v Although a single fan failure in one of the power supplies is not a critical

event, it is recommended that you install a new power supply when one of the two fans in either power supply stops working.

v When hot-swapping power supplies, remove and install the power supplies

within two minutes.

Attention: Your EXN1000 can run with one power supply removed for a maximum of two minutes. The airflow through your EXN1000 is degraded when only one power supply is present and operating. Therefore, if the power supplies are not replaced within two minutes, the system halts and no data is accessible.

v Have the replacement power supply close by and ready to install before

removing the old one.

CAUTION: Never remove the cover on a power supply fan unit. There are no serviceable parts inside these components. If you suspect a problem with one of these parts, contact a service technician.
