Seismically hardened two-post electronic equipment rack

Abstract

A two-post mounting rack includes a frame bottom, a frame top, a pair of frame uprights interconnected between the frame bottom and the frame top, and a base assembly for supporting the frame bottom on a surface. One or more of the frame bottom, the frame top, the pair of frame uprights, and the base assembly are seismically hardened. Each frame upright has a closed cross-sectional shape. Each frame upright includes a flange with apertures adapted to provide a mounting location for cable management projections. The base assembly includes two separate end gusset members. Each end gusset member includes two corner gussets. Each corner gusset includes a floor plate and a riser plate. The two corner gussets in each end gusset member are connected by a bridge member. The frame top includes an upper cross-member and two lateral reinforcement plates.

       3 . The seismically hardened two-post mounting rack of  claim 1 , wherein the closed cross-sectional shape is fabricated by welding together an inner channel member and an outer channel member. 
   
   
       4 . The seismically hardened two-post mounting rack of  claim 3 , wherein each of the inner and outer channel members is generally Unshaped in cross section. 
   
   
       5 . The seismically hardened two-post mounting rack of  claim 4 , wherein the inner and outer channel members jointly define the closed cross-sectional shape. 
   
   
       6 . The seismically hardened two-post mounting rack of  claim 4 , wherein the inner channel member has wings extending outwardly at either side of the U shape of the inner channel member at an angle that is generally perpendicular to opposing sides of the U shape. 
   
   
       7 . The seismically hardened two-post mounting rack of  claim 6 , wherein the wings are welded to the interior base of the U shape of the outer channel member to define the closed cross-sectional shape. 
   
   
       8 . The seismically hardened two-post mounting rack of  claim 1 , further comprising a base assembly for supporting the frame bottom on a surface. 
   
   
       9 . The seismically hardened two-post mounting rack of  claim 1 , further comprising a power outlet attached to the frame bottom. 
   
   
       10 . The seismically hardened two-post mounting rack of  claim 1 , further comprising a power strip attached to a frame upright. 
   
   
       11 . The seismically hardened two-post mounting rack of  claim 1 , further comprising one or more cable guides attached to a frame upright. 
   
   
       12 . The seismically hardened two-post mounting rack of  claim 1 , further comprising a cable raceway attached to the frame top. 
   
   
       13 . A seismically hardened two-post mounting rack comprising:
