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

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

Terminology
In this and other IBM N series documents, the term filer or storage system
describes IBM N series models that either contain internal disk storage or
attach to the disk storage expansion units specifically designed for the IBM N
series storage systems. There are three disk storage expansion units
specifically designed for the IBM N series:
v IBM EXN4000 fibre-channel disk storage expansion unit
v IBM EXN2000 fibre-channel disk storage expansion unit
v IBM EXN1000 serial advanced technology attachment (SATA) storage
expansion unit
Note:
This guide uses the following terms:
v Active-Active configuration (sometimes referred to as clustered configuration)
refers to a High Availability system with at least two nodes that share
resources to provide redundancy.
v AT-FCX refers to the EXN1000 module.
v Device carrier refers to the container that encases a fan/power supply unit
or a disk.
v Disk applies to any SATA disk encased in its device carrier.
v Disk shelf or expansion unit refers to any shelf or expansion unit containing
hard disk drives.
v Loop refers to one or more daisy-chained EXN1000 expansion units
