Safety notices vii

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.

(R001 part 1 of 2)

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.

viii IBM System Storage: N6200 Series Hardware and Service Guide

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.

(R001 part 2 of 2)

Safety notices ix

Rack relocation (19" 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.

(R002)

x IBM System Storage: N6200 Series Hardware and Service Guide

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.

Fire suppression systems

A fire suppression system is the responsibility of the customer. The customer's own insurance underwriter, local fire marshal, or a local building inspector, or both, should be consulted in selecting a fire suppression system that provides the correct level of coverage and protection.

IBM designs and manufactures equipment to internal and external standards that require certain environments for reliable operation. Because IBM does not test any equipment for compatibility with fire suppression systems, IBM does not make compatibility claims of any kind nor does IBM provide recommendations on fire suppression systems.

Terminology and conventions used in this document

This guide uses the following terminology, command conventions, format conventions and keyboard conventions.

In this document, the term gateway describes IBM N series storage systems that have been ordered with gateway functionality. Gateways support various types of storage, and they are used with third-party disk storage systems. In this case, disk storage for customer data and the RAID controller functionality is provided by the back-end disk storage system. A gateway might also be used with disk storage expansion units specifically designed for the IBM N series models.

The term filer describes IBM N series storage systems that either contain internal disk storage or attach to disk storage expansion units specifically designed for the IBM N series storage systems. Filer storage systems do not support using third-party disk storage systems.

The terms system or storage system refer to either a gateway by itself or a filer, either by itself or with additional disk drives.

Active/active and high-availability terms

active/active configuration

In the Data ONTAP 7.2 and 7.3 release families, refers to a pair of storage systems (sometimes called nodes) configured to serve data for each other if one of the two systems stops functioning. Also sometimes referred to as active/active pairs.

cluster

In the Data ONTAP 7.1 release family, refers to a pair of storage systems (sometimes called nodes) configured to serve data for each other if one of the two systems stops functioning. In Data ONTAP 8.x ,acluster is a group of connected nodes (storage systems) that share a global namespace and that you can manage as a single virtual server or multiple virtual servers, providing performance, reliability, and scalability benefits.

HA (high availability)

In Data ONTAP 8.x, the recovery capability provided by a pair of nodes (storage systems), called an HA pair, that are configured to serve data for each other if one of the two nodes stops functioning.

HA pair

In Data ONTAP 8.x, a pair of nodes (storage systems) configured to serve data for each other if one of the two nodes stops functioning.

Storage terms

ACP Alternate Control Path is a protocol that enables Data ONTAP to manage

and control the storage expansion unit storage subsystem using a separate network from the data path, so management communication is not dependent on the data path being intact and available.

AT-FCX

The controller module of the EXN1000 serial advanced technology attachment (SATA) storage expansion unit.

Preparing for the installation 3

Handling static-sensitive devices

CAUTION: This system 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.
