Physical Installation

Mounting the Wide Bank 28 DS3

Vertical Mounting in a Standard EIA or WECO Rack

This mounting configuration requires an ambient air temperature below 77

F (25

C),

without supplemental cooling. In spaces where ambient temperature can rise above

F, install a fan tray (600 CFM or more) below the rows of Wide Banks. The fan tray

must direct the air up through the units.

The Wide Banks can be vertically mounted in either a standard EIA/WECO 19-inch

rack or a standard EIA/WECO 23-inch rack using the mounting brackets shipped with

the unit, and optional Carrier Access Vertical Mount Crossbars (PN 710-0003 for 19-

inch racks and PN 710-0004 for 23-inch racks). See Figure 4-4 for an illustration of

mounting in both sizes of racks.
