Attention notices
An attention notice indicates the possibility of damage to a program, device, or
system, or to data. An exclamation point symbol may accompany an attention
notice, but is not required. A sample attention notice follows:
A hazardous electrical condition with less severity than
electrical danger.
A generally hazardous condition not represented by other
safety symbols.
A hazardous condition due to the use of a laser in the
product. Laser symbols are always accompanied by the
classification of the laser as defined by the U. S.
Department of Health and Human Services (for example,
Class I, Class II, and so forth).
Attention: Do not bend a fibre cable to a radius less than 5 cm (2 in.);
you can damage the cable. Tie wraps are not recommended for optical
cables because they can be easily overtightened, causing damage to the
cable.
Safety notices v
Laser safety

Rack safety
Rack installation
About this task
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.
Safety notices vii
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)
viii IBM System Storage: N7000 Series Hardware and Service Guide
Rack relocation (19" rack)
About this task
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)
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 7-Mode, a cluster 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 7-Mode, 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 (ACP) 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.
xxii IBM System Storage: N7000 Series Hardware and Service Guide
Disk Any hard disk drive
Disk shelf or shelf
Any storage expansion unit containing hard disk drives.
ESH The controller module of Fibre Channel disk storage expansion units.
IOM The Input/Output module of SAS disk storage expansion units.
Loop or Fibre-Channel Arbitrated Loop
One or more daisy-chained Fibre Channel storage expansion units
connected to an N series storage system.
Motherboard tray
The system controller module that executes the software on an N7000
series system. The motherboard tray is at the rear of the N7000 series
system.
Node The system controller module that executes the software on an N series
system. There is one node in the single-controller models; there are two
nodes in active/active or high availability models.
Stack or SAS stack
A stack of one or more SAS storage expansion units using IOM modules
connected to the storage system. The maximum number of storage
expansion units in a stack of storage expansion units and the number of
storage expansion unit stacks in a configuration are dependent on the type
of storage system.
Command conventions
You can enter commands on the system console or from any client that can obtain
access to the storage system using a Telnet session. In examples that illustrate
commands executed on a UNIX workstation, the command syntax and output
might differ, depending on your version of UNIX.

v 7-mm nut driver (required if removing or installing storage expansion units)
Handling static-sensitive devices
About this task
Attention: The N7000 series 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.
1
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.
