Safety notices

Important

Each caution and danger statement in this documentation is labeled with a number. You can use this number to cross-reference an English-language CAUTION or DANGER statement with converted versions of the caution or danger statement in the Safety Notices Translation document (PN G229-9054).

For example, if a caution statement is labeled D005, conversions for that caution statement are in the Safety Notices conversion document under D005. Be sure to read all caution and danger statements in this documentation before you complete the procedures. Read any additional safety information that comes with your system or optional device before you install the device.

Danger: Overloading a branch circuit is potentially a fire hazard and a shock hazard under certain conditions. To avoid these hazards, ensure your system electrical requirements do not exceed branch circuit protection requirements. Refer to the information that is provided with your device or the power rating label for electrical specification (D002)

Danger: If the receptacle has a metal shell, do not touch the shell until you have completed the voltage and grounding checks. Improper wiring or grounding might place dangerous voltage on the metal shell. If any of the conditions are not as described, STOP. Ensure that the improper voltage or impedance conditions are corrected before proceeding. (D003)

Danger: Hazardous voltage, current, or energy levels are present inside any component that has the label that is attached. Do not open any cover or barrier that contains this label. (L001)

CAUTION: The weight of this part or unit is between 18 and 32 kg (39.7 and 70.5 lb). It takes two persons to safely lift this part or unit. (C009)

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. Although shining light into one end and looking into the other end of a disconnected optical fiber to verify the continuity of optic fibers might not injure the eye, this procedure is potentially dangerous. Therefore, verifying the continuity of optical fibers by shining light into one end and looking at the other end is not recommended. To verify continuity of a fiber optic cable, use an optical light source and power meter. (C027)

Danger: High Leakage Current. Earth connection is essential before connecting supply. (LT020)

CAUTION: A hot surface nearby. (L007)

DANGER: Multiple power cords. The product might be equipped with multiple AC power cords or multiple DC power cables. To remove all hazardous voltages, disconnect all power cords and power cables. (L003)

(R001 part 1 of 2):

DANGER: Observe the following precautions when working on or around your IT rack system:

• Heavy equipment–personal injury or equipment damage might result if mishandled.
• Always lower the leveling pads on the rack cabinet.
• Always install stabilizer brackets on the rack cabinet unless the earthquake option is to be installed.
• 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.

• Rack-mounted devices are not to be used as shelves or workspaces. Do not place objects on top of rack-mounted devices. In addition, do not lean on rack-mounted devices and do not use them to stabilize your body position (for example, when working from a ladder).
• Each rack cabinet might have more than one power cord.
  • For AC-powered racks, be sure to disconnect all power cords in the rack cabinet when directed to disconnect power during servicing.
  • For racks with a DC power distribution panel (PDP), turn off the circuit breaker that controls the power to the system units, or disconnect the customer’s DC power source, when directed to disconnect power during servicing.
• 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 that is installed in one rack cabinet into a power device that is installed in a different rack cabinet.
• An electrical outlet that is not correctly wired might 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 2 of 2):

CAUTION:

• Do not install a unit in a rack where the internal rack ambient temperatures exceed the manufacturer's recommended ambient temperature for all your rack-mounted devices.
• 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.
• 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 on the equipment in the rack to determine the total power requirement of the supply circuit.
• (For sliding drawers.) Do not pull out or install any drawer or feature if the rack stabilizer brackets are not attached to the rack or if the rack is not bolted to the floor. 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.
• (For fixed drawers.) This drawer is a fixed drawer and must not be moved for servicing unless specified by the manufacturer. Attempting to move the drawer partially or completely out of the rack might cause the rack to become unstable or cause the drawer to fall out of the rack.

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.

• 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 observe the following precautions:
  • Remove all devices in the 32U position (compliance ID RACK-001) or 22U (compliance ID RR001) and above.
  • Ensure that the heaviest devices are installed in the bottom of the rack cabinet.
  • Ensure that there are little-to-no empty U-levels between devices that are installed in the rack cabinet below the 32U (compliance ID RACK-001) or 22U (compliance ID RR001) level, unless the received configuration specifically allowed it.
• 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.
• 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 that is installed on the rack cabinet during movement.
• Do not use a ramp that is 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 or in an earthquake environment bolt the rack to the floor.
  • 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 of the pallet and bolt the rack cabinet to the pallet. (R002)
