Verify the Rack Meets the Specifications for Installing a KMA

Verify the rack is compatible before installing the KMA. The rack should be a standard, RETMA 19-inch, four post rack or cabinet.

Note:

Two-post racks are not supported by the T7-1 or T8-1 servers. The T4-1 server can be installed in a four post or two post rack or cabinet.

Only 9.5 mm square hole and M6 round mounting holes are supported.

The sliding rails are compatible with racks which meet the following standards:

• Horizontal opening and unit vertical pitch conforming to ANSI/EIA 310-D-1992 or IEC 60927 standards.
• Distance between front and rear mounting planes between 610 mm and 915 mm (24 in. to 36 in.).
• Clearance depth to a front cabinet door must be at least 27 mm (1.06 in.).
• Clearance depth to a rear cabinet door at least 900 mm (35.5 in.) to incorporate cable management or 700 mm (27.5 in.) without cable management.
• Clearance width between structural supports and cable troughs and between front and rear mounting planes is at least 456 mm (18 in.).

Provide adequate service clearance for rack components:

• Front service clearance 48.5 in. (1.23 m) minimum
• Rear service clearance 36 in. (914.4 mm) minimum

Consider the total weight when you place equipment into the rack. To prevent an unbalanced situation:

• Load equipment in a rack from the bottom to the top.
• Install the heaviest equipment on the bottom and the lightest on the top.
• Install an anti-tilt bar (if necessary) to provide additional stability.

Verify there is adequate cooling for the servers.

• Ensure that the temperature in the rack does not exceed the maximum ambient rated temperatures for all of the equipment installed in the rack.
• Ensure that there is adequate cooling to support all of the equipment in the rack.

Verify the rack has the proper power connections and ground.

• When removing power from any equipment, make sure it does not effect other equipment in the rack.
