3.5.1. Sealing the Holes of the Top Plate of the Cabinet
Holes are reserved at the top of the cabinet to facilitate smooth on-site installation as well as the connection
of the rack on the top of the machine room. After the cabinet is installed on the site, seal the remaining holes
using rubber plugs and bolts. Use M13.5 rubber plugs to seal four holes at the top of the cabinet and M12x30
bolts to seal 8 holes at the top plate of the cabinet. This prevents water from entering the cabinet.
Figure 3-24 shows the sealing the holes on the top plate of the cabinet.
