• The system requires space at the rear of the rack for system brackets and cables.
• Only ac power drawers are supported in the rack or cabinet. It is strongly recommended to use a power
distribution unit that meets the same specifications as IBM power distribution units to supply rack
power (for example, feature code 7188). Rack or cabinet power distribution devices must meet the
drawer voltage, amperage, and power requirements, as well as that of any additional products that are
connected to the same power distribution device.
The rack or cabinet power receptacle (power distribution unit, uninterruptible power supply, or multi-
outlet strip) must have a compatible plug type for your drawer or device.
• The rack or cabinet must be compatible with the drawer-mounting rails. The rail-mounting pins and
screws must fit securely and snugly into the rack or cabinet rail-mounting holes. The mounting rails
and mounting hardware that are provided with IBM products are designed and tested to safely support
the product during operation and service activities, and to safely support the weight of your drawer
or device. The rails must facilitate service access by allowing the drawer to be safely extended,
if necessary, forward, backward, or both. Some rails, with IBM features for non-IBM racks, provide
drawer-specific anti-tip brackets, rear lock-down brackets, and cable management guides that require
clearance on the rear side of the rails.
Note: If the rack or cabinet has square holes on the mounting flanges, an adapter might be required.
• The rack or cabinet must have stabilization feet or brackets installed in the front of the rack, or have
another means of preventing the rack/cabinet from tipping while the drawer or device is pulled into its
extreme front service positions.
Note: Examples of some acceptable alternatives: The rack or cabinet might be securely bolted to the
floor, ceiling or walls, or to adjacent racks or cabinets in a long and heavy row of racks or cabinets.
• If present, front and rear doors must be able to open far enough to provide unrestrained access for
service or be easily removable. If doors must be removed for service, it is the responsibility of the
customer to remove them before service.
• Front and rear doors must not violate the previously defined front and rear rack space that is required
for the system.
• The rack or cabinet must provide adequate front-to-back ventilation.
Note: Rack doors must be fully perforated to provide proper front-to-back airflow for mounted
Information Technology (IT) equipment. The total door area must result in a minimum of 45% opening
area. Rear doors must not create back pressure that can interfere with the enclosure fan operation.
