Mounting the Wide Bank 28 DS3
4-8 July 2004 Wide Bank 28 DS3 - Release 2.4
If other crossbar structures are used to mount the Wide Banks, align the units vertically, as
shown in Figure 4-3, to provide a conduit for convective air flow.
Using a 19-inch rack and crossbars 710-0003, six units can be mounted in each of three
horizontal rows, for a total of 18 Wide Banks. Do not mount any other Wide Banks
(horizontally) above or below the vertically-mounted units. Fan trays may be mounted below,
and fuse panels above but no heat-dissipating equipment or passive structures that impede
natural air flow.
Using a 23-inch rack and crossbars 710-0004, eight units can be mounted in each of three
horizontal rows, for a total of 24 Wide Banks. Do not mount any other Wide Banks
(horizontally) above or below the vertically-mounted units. Fan trays can be mounted below,
and fuse panels above but no heat-dissipating equipment or passive structures that impede
natural air flow.
