General rack specifications
A standard equipment rack is nominally 19 inches wide (including
mounting hardware) and follows a standard set by the Electronics
Industry Alliance (EIA)
The 19-inch rack standard is called EIA-310-D, which is essentially
equivalent to IEC-60297-3-100 or DIN 41494 in other regions.

post rack can be used for mounting the hdHost PS, airhost PS or
hd33 PS remote
Racks may be open or closed
Racks must be secured with floor or ceiling according to appropriate
local building or seismic codes.
Reinforce equipment racks with support brackets or rails as
necessary to accommodate the weight of units
Rack mounting and clearances
The rack should be mounted to the floor and levelled. Adhere to
any applicable local or seismic guidelines for equipment installation.
Allow a minimum clearance of 24 in (610 mm) at the rear of the
rack for access to grounding lug and cooling fans.
Rack grounding
Install a ground bar bus on the rack to accept the ground wires from
each unit in the rack.
Use #10 AWG ground cable from the main facility ground to the
rack grounding bus bar.
Rack cable management
Install 1RU cable management trays above and below units in the
rack and vertical cable management trays for managing RF, optical,
