• Do not stand under overhanging load.
• Do not use on uneven surface, incline or decline (major ramps).
• Do not stack loads.
• Do not operate while under the influence of drugs or alcohol.
• Do not support ladder against LIFT TOOL.
• Tipping hazard. Do not push or lean against load with raised platform.
• Do not use as a personnel lifting platform or step. No riders.
• Do not stand on any part of lift. Not a step.
• Do not climb on mast.
• Do not operate a damaged or malfunctioning LIFT TOOL machine.
• Crush and pinch point hazard below platform. Only lower load in areas clear of personnel and

obstructions. Keep hands and feet clear during operation.

• 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, fingers, 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)

CAUTION: If the System slide rails are installed above EIA location 29U, the [ServerLIFT

] tool (or

other qualified lift tool) must be used as a safety precaution for servicing. Position the lift tool

platform slightly below the bottom of the System drawer to account for the slight downward flex

when the drawer is extended out fully on its slides. Then gently raise the lift tool platform to stably

contact the bottom of the drawer, minding not to over force it as it could put upward stress to the

slide rails. A service-qualified ladder may have to be used to reach or properly work around the

System at such heights. While using a ladder, do not lean on or against the system drawer or lift

tool during service, and follow safe practices. (C051)
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)

About this task

Important: The 5U92 disk enclosure is heavy. Before you install the expansion enclosure in the rack for

the first time or replace it in the rack to complete a service task, review and implement the following

tasks:
• Always use a suitably rated mechanical lift or four persons to raise the enclosure to install it in the rack.

Even after the drives, power supply units, secondary expander modules, canisters, fans, and top cover

are removed, the enclosure weighs 43 kg (95 lbs).

• Install the disk enclosure in the lowest position in the rack. Figure 27 on page 36 shows an example.
