Page: 337 / 410

Each GR2000 model can be mounted in a 19-inch rack conforming to JIS and EI
standards. When you choose this style of installation, ensure that the rack and t
router meet the minimum service clearance requirements, the cooling requiremen
and the general rules as previously mentioned. Then, follow one of the procedure
below depending on the scale of the subject model: small, medium, or large.
6.3.4.1 Rack-Mount Installation of Small-Scale Chassis—GR2000-2S, GR2000-4, GR2000-4S,
GR2000-6H
Figure 6-27 to Figure 6-30 show the rack-mount installation of GR2000-2S,
GR2000-4, GR2000-4S and GR2000-6H (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 on the front end for interfa
cables and 70mm on the rear end for power cables). For GR2000-2S/4S/
(depth 480 mm), the inner depth of the rack must be at least 580mm. For
GR2000-4 (depth 600 mm), the inner depth of the rack must be at least
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).
