Cautions and warnings apply when you are installing or servicing components in the cabinet. Only a technically-qualified field engineer should service the system.
Failure to observe these precautions can kill or injure personnel or damage the system.
General Cabinet Servicing
Do not extend more than one chassis in a cabinet at a time.
Do not compromise the weight distribution in the cabinet when removing or installing chassis.
Some chassis can weigh 50 pounds or more. If you must remove a chassis from the rack, two or more people may be required.
Power on/off switches or buttons on chassis do not completely remove AC power. Do not service a non-hot-pluggable component unless the power off procedure has been performed and the AC power cord has been unplugged from the chassis .
The cabinet contains more than one AC power cord. To remove all power from the cabinet, you must disconnect all AC power cords from the site power source. Install the power outlets so they are near the equipment and easily accessible.
Do not plug unauthorized equipment into the AC feeder box. The AC feeder box provides at least 200 volts which will damage 120 volt equipment.
Hazardous electrical conditions may be present on chassis and on power, telephone, and communications cables. Take appropriate precautions.
AC Input Rating Labels
AC input rating labels indicate the supply voltage and maximum number of Amps for the following cabinet components.
- Cabinets with AC feeder boxes contain two or four AC feeder boxes per cabinet. AC feeder boxes are mounted inside the rack on the right and left sidewalls. Each AC feeder box has one label.
- Cabinets with AC boxes (blue and orange). AC boxes are mounted in U spaces at the bottom of the cabinet. Each AC box has one label.
The AC input rating label is located next to the AC power cord that connects to site power. (The site power cord is the power cord that leaves the cabinet through the top or bottom openings in the cabinet.)
Electrostatic Discharge Protection
Not following electrostatic discharge (ESD) precautions can damage your system.
Failure to completely and correctly seat a component, board, or adapter can result in damage to these parts.
ESD can damage disk drives, boards, adapters, and other parts. However, the chassis can withstand normal levels of environmental ESD while you are hot-swapping components.
Perform all service procedures only at an ESD workstation.
Wear an anti-static wrist strap attached to an unpainted metal surface on the rack or chassis when handling parts.
Always handle boards and adapters carefully and only by their edges.
After removing a board or adapter from its protective wrapper or from a chassis, place it component-side up on a grounded, static-free surface, or on a conductive foam pad.
Do not use the board or adapter protective wrapper in place of a grounded, static-free surface or conductive foam pad.
Do not slide a board or adapter over any surface.
Do not use equipment mounted on slides or rails as a shelf or work space.
Only push cabinet from front. Only roll over solid floor tiles.
To avoid power overload in a processing/storage cabinet, only cabinet builds documented in the "Cabinet Builds for Aster" section of the Product and Site Preparation Guide, Hardware Installation Guide, or Hardware Service Guide are supported. Gray shaded areas in the cabinet build illustrations designate locations that do not support chassis. Installing chassis in these locations may result in a power overload if power to one side of the cabinet is lost.
Cabinets with Type A power do not support as many chassis in the cabinets as cabinets with Type B, C, or D power.
