Best practices for deployment in rows
Baying kits are used to physically connect adjacent racks to create a row of two or more units. Racks that
are bayed together with a baying kit are more stable and reduce the potential tipping of the rack. If racks
are secured together with baying kits, the side feet installed on each end of the row of racks are
considered optional.
If gaps are created between racks that could allow airflow from the rear of the rack, these gaps should be
sealed with an appropriate material that will not cause particulate or electro-static discharge issues.
Fixed stabilizers are anti-tip side feet (front and side) that provide stability and support when equipment is
installed, removed, or accessed within the rack. Rack rows with four or more bayed racks do not need a
stabilizer kit installed. For single racks or bays of three racks, with no component exceeding 100 kg (220
lb), a standard 600 mm stabilizer is required.
If a standard 600 mm (23.62 in) or 800 mm (31.50 in) front stabilizing foot is installed on a stand-alone
rack, the side feet, provided with the fixed stabilizer kit, should also be installed.
A heavy duty 600 mm (23.62 in) front stabilizer foot is required in any of the following situations:
•
A single rack-mountable component weighing 100 kg (220 lb) or greater is installed in a stand-
alone rack.
•
A row of three or fewer racks are bayed together.
•
Side feet, which are included in the stabilizer kits, should also be installed to stabilize the rack.
