Safety notices

A danger notice indicates the presence of a hazard that has the potential of causing

death or serious injury. A caution notice indicates the presence of a hazard that has

the potential of causing moderate or minor personal injury.

Note: For translated safety notices, see Systems Safety Notices (G229-9054). This

document is included on the DR550 Documentation CD.

Electrical safety

Observe the following safety instructions during installation and service activities.

DANGER

v

An electrical outlet that is not correctly wired could place hazardous

voltage on 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.

v Before installing or removing signal cables, ensure that the power cables

for the system unit and all attached devices are unplugged.

v When adding or removing any additional devices to or from the system,

ensure that the power cables for those devices are unplugged before the

signal cables are connected. If possible, disconnect all power cables from

the existing system before you add a device.

v Use one hand, when possible, to connect or disconnect signal cables to

prevent a possible shock from touching two surfaces with different

electrical potentials.

v During an electrical storm, do not connect cables for display stations,

printers, telephones, or station protectors for communications lines.

v To prevent electrical shock hazard, disconnect all power cables from the

electrical outlet before relocating the system.

CAUTION:

v This product is equipped with a three-wire power cable and plug for the

user's safety. Use this power cable with a properly grounded electrical outlet

to avoid electrical shock.

v The DR550 DR2 is configured with two mainline power cords.

Laser safety

This equipment contains Class 1 laser products, and complies with FDA radiation

Performance Standards, 21 CFR Subchapter J and the international laser safety

standard IEC 60825-1.

CAUTION:

Data processing environments can contain equipment transmitting on system

links with laser modules that operate at greater than Class 1 power levels. For

this reason, never look into the end of an optical fiber cable or open receptacle.

Attention: In the United States, use only SFP or GBIC optical transceivers that

comply with the FDA radiation performance standards, 21 CFR Subchapter J.

Internationally, use only SFP or GBIC optical transceivers that comply with IEC

standard 60825. Optical products that do not comply with these standards may

produce light that is hazardous to the eyes.

Rack safety

DR550 Rack installation

DANGER

v

Always lower the leveling pads on the rack cabinet.

v Always install stabilizer brackets on the rack cabinet.

v Rack-mounted devices are not to be used as a shelf or work space. Do not place any

object on top of rack-mounted devices.

v Each rack cabinet might have more than one power cord. Be sure to disconnect all

power cords in the rack cabinet before servicing any device in the rack cabinet.

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.

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 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.

v 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 may become unstable if more than one drawer at a time is pulled

out.

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)

xii DR550 Version 4.5 Problem Determination and Service Guide

DR550 Rack relocation

CAUTION:

Follow these general guidelines whenever a populated rack cabinet is relocated

within a room or building:

v If the rack cabinet that is being relocating is part of a suite of rack cabinets,

detach the rack cabinet from the suite.

v Inspect the route that you plan to take when moving the rack to eliminate

potential hazards.

v 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.

v Verify that all door openings are at least 760 x 2030 mm (30 x 80 in.).

v Ensure that all devices, shelves, drawers, doors, and cables are secure.

v Ensure that the four leveling pads are raised to their highest position.

v Ensure that there is no stabilizer bracket installed on the rack cabinet during

movement.

v Do not use a ramp inclined at more than ten degrees.

v Once the rack cabinet is in the new location, do the following:

– Lower the four leveling pads.

– Install stabilizer brackets on the rack cabinet.

v

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.

Safety inspections

Perform the following safety checks to identify unsafe conditions. Be cautious of

potential safety hazards that are not covered in the safety checks. If unsafe

conditions are present, determine how serious the hazards are and whether you

should continue before you correct the problem.

Removing AC power

Perform the following steps to remove the AC power:

1. Ensure customer system activity has stopped.

2. Perform a controlled system shutdown.

3. Set the power switches on the DR550 components to the off position.

4. For a DR550 DR2, set the power switch on the DR550 rack, located in front

upper right corner, to the off position.

5. Disconnect the power cables from the power source.

DANGER

Multiple

power cords. (L003)

Safety notices xiii

External machine checks

Perform the following external machine checks:

1. Verify that all external covers are present and are not damaged.

2. Ensure that all latches and hinges are in correct operating condition.

3. Check the power cable for damage.

4. Check the external signal cable for damage.

5. Check the cover for sharp edges, damage, or alterations that expose the internal

parts of the device.

6. Correct any problems that you find.

Internal machine checks

Perform the following internal machine checks:

1. Check for any non-IBM changes that might have been made to the machine. If

any are present, obtain the Non-IBM Alteration Attachment Survey form, number

R009, from the IBM

®

branch office. Complete the form and return it to the

branch office.

2. Check the condition of the inside of the machine for:

v Metal or other contaminants

v Indications of water or other fluid

v Fire

v Smoke damage

3.

Check for any obvious mechanical problems, such as loose components.

4. Check any exposed cables and connectors for wear, cracks, or pinching.
