Hitachi GR2000 manual

GR2000-20 (unit: mm). The steps are as follows:

1. Prepare the 19-inch rack, considering the dimensions of the router chassis.

The inner depth of the rack must accommodate the depth of the router chassis plus minimum cable clearance (30mm for interface cables and 70m for power cables) and minimum airway clearance (30mm). For GR2000-20 and GR2000-20 (depth 600 mm), the inner depth of the rack must be at le 700mm. If a rack with a door is selected, make sure that the distance between the chassis front end and the inner surface of the door satisfies t said minimum cable clearance (30mm).

2. ￿￿Mount the load-bearing guide rail (accessory of the rack) on the rack. Make s that the guide rail can sustain the mass of the chassis (max. 160kg per GR2000-20H and max. 190kg per GR2000-20). Align the guide rails to suppo the bottom of the chassis and, if another router is to be mounted above this router, to secure a space of 1U (44.45 mm) or more on top of the router when mounted.

The width of the opening of the rack must accommodate the width of the router chassis plus minimum allowance of 10mm for the thickness of me brackets to be attached to both sides of the chassis. For GR2000-20H and GR2000-20 (width 440 mm), the width of the opening of the rack must be least 450mm.
