4 IBM Elastic Storage System 3000: Hardware Planning and Installation Guide

• Connect and disconnect cables as described in the following procedures when installing,
moving, or opening covers on this product or attached devices.
To disconnect:
1. Turn off everything (unless instructed otherwise).
2. Remove the power cords from the outlets.
3. Remove the signal cables from the connectors.
4. Remove all cables from the devices.
To connect:
1. Turn off everything (unless instructed otherwise).
2. Attach all cables to the devices.
3. Attach the signal cables to the connectors.
4. Attach the power cords to the outlets.
5. Turn on the devices.
• Sharp edges, corners and joints might be present in and around the system. Use care when
handling equipment to avoid cuts, scrapes and pinching. (D005)
DANGER: Heavy equipment–personal injury or equipment damage might result if mishandled.
(D006)
DANGER: Serious injury or death can occur if loaded lift tool falls over or if a heavy load falls off
the lift tool. Always completely lower the lift tool load plate and properly secure the load on the lift
tool before moving or using the lift tool to lift or move an object. (D010)
DANGER: Racks with a total weight of > 227 kg (500 lb.), Use Only Professional Movers! (R003)
DANGER: Do not transport the rack via fork truck unless it is properly packaged, secured on top of
the supplied pallet. (R004)
DANGER:
Main Protective Earth (Ground):
This symbol is marked on the frame of the rack.
The PROTECTIVE EARTHING CONDUCTORS should be terminated at that point. A recognized or
certied closed loop connector (ring terminal) should be used and secured to the frame with a lock
washer using a bolt or stud. The connector should be properly sized to be suitable for the bolt or
stud, the locking washer, the rating for the conducting wire used, and the considered rating of the
breaker. The intent is to ensure the frame is electrically bonded to the PROTECTIVE EARTHING
CONDUCTORS. The hole that the bolt or stud goes into where the terminal conductor and the lock
washer contact should be free of any non-conductive material to allow for metal to metal contact.
All PROTECTIVE EARTHING CONDUCTORS should terminate at this main protective earthing
terminal or at points marked with . (R010)

Latest revision manual available on vendor's website.
• Test verify stabilizer brake function before each use. Do not over-force moving or rolling the
LIFT TOOL with stabilizer brake engaged.
• Do not raise, lower or slide platform load shelf unless stabilizer (brake pedal jack) is fully
engaged. Keep stabilizer brake engaged when not in use or motion.
• Do not move LIFT TOOL while platform is raised, except for minor positioning.
• Do not exceed rated load capacity. See LOAD CAPACITY CHART regarding maximum loads at
center versus edge of extended platform.
• Only raise load if properly centered on platform. Do not place more than 200 lb (91 kg) on
edge of sliding platform shelf also considering the load's center of mass/gravity (CoG).
• Do not corner load the platform tilt riser accessory option. Secure platform riser tilt option to
main shelf in all four (4x) locations with provided hardware only, prior to use. Load objects are
designed to slide on/off smooth platforms without appreciable force, so take care not to push

•No Forks. Never lift or move bare LIFT TOOL MACHINE with pallet truck, jack or fork lift.
•Mast extends higher than platform. Be aware of ceiling height, cable trays, sprinklers, lights, and
other overhead objects.
•Do not leave LIFT TOOL machine unattended with an elevated load.
•Watch and keep hands, ngers, and clothing clear when equipment is in motion.
•Turn Winch with hand power only. If winch handle cannot be cranked easily with one hand, it is
probably over-loaded. Do not continue to turn winch past top or bottom of platform travel.
Excessive unwinding will detach handle and damage cable. Always hold handle when lowering,
unwinding. Always assure self that winch is holding load before releasing winch handle.
•A winch accident could cause serious injury. Not for moving humans. Make certain clicking sound
is heard as the equipment is being raised. Be sure winch is locked in position before releasing
handle. Read instruction page before operating this winch. Never allow winch to unwind freely.
Freewheeling will cause uneven cable wrapping around winch drum, damage cable, and may
cause serious injury. (C048, part 2 of 2)
CAUTION:
High levels of acoustical noise are (or could be under certain circumstances) present.
Use approved hearing protection and/ or provide mitigation or limit exposure. (L018)
CAUTION: Removing components from the upper positions in the rack cabinet improves rack
stability during a relocation. Follow these general guidelines whenever you relocate a populated
rack cabinet within a room or building.
• 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 conguration of the rack cabinet as you
received it. If this conguration is not known, you must observe the following precautions.
– 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.
• If the rack cabinet you are relocating was supplied with removable outriggers they must be
reinstalled before the cabinet is relocated.
• Inspect the route that you plan to take to eliminate potential hazards.
Chapter 1. Notices 7

• Verify that the route that you choose can support the weight of the loaded rack cabinet. Refer to
the documentation that comes with your rack cabinet for the weight of a loaded rack cabinet.
• Verify that all door openings are at least 760 x 230 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 10 degrees.
• When the rack cabinet is in the new location, complete the following steps:
– 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 conguration 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 the pallet and bolt the rack cabinet to the
pallet. (R002)

General safety
When you service the Elastic Storage System 3000 , follow general safety guidelines.
Use the following general rules to ensure safety to yourself and others.
• Observe good housekeeping in the area where the devices are kept during and after maintenance.
• Follow the guidelines when lifting any heavy object:
1. Ensure that you can stand safely without slipping.
2. Distribute the weight of the object equally between your feet.
3. Use a slow lifting force. Never move suddenly or twist when you attempt to lift.
4. Lift by standing or by pushing up with your leg muscles; this action removes the strain from the
muscles in your back. Do not attempt to lift any objects that weigh more than 18 kg (40 lb) or objects
that you think are too heavy for you.
• Do not perform any action that causes a hazard or makes the equipment unsafe.
• Before you start the device, ensure that other personnel are not in a hazardous position.
• Place removed covers and other parts in a safe place, away from all personnel, while you are servicing
the unit.
• Keep your tool case away from walk areas so that other people cannot trip over it.
• Do not wear loose clothing that can be trapped in the moving parts of a device. Ensure that your sleeves
are fastened or rolled up above your elbows. If your hair is long, fasten it.
• Insert the ends of your necktie or scarf inside clothing or fasten it with a nonconducting clip,
approximately 8 cm (3 in.) from the end.
• Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your clothing.
Remember: Metal objects are good electrical conductors.
• Wear safety glasses when you are hammering, drilling, soldering, cutting wire, attaching springs, using
solvents, or working in any other conditions that might be hazardous to your eyes.
