Projected Temperature Vs Energy Output
To ensure adequate cooling in systems using an extractor fan assembly, all
unused front panel space must be covered with blank filler panels and the rear
door must be closed.
Weight and Balance
Slide-mounted products and work surface/keyboard products need weight and
balance calculations performed to determine the need for ballast to reduce the
risk of cabinet instability. The worksheets for both are provided on the following
pages. If both slide-mounted and work surface/keyboard products are being
used, calculate both and add the results.
Slide-Mounted Products
To reduce the risk of rack instability when operator serviceable, slide-mounted
products are installed, use the following worksheet to determine the need for
additional counterweight ballast. If there are no operator serviceable, slide-
mounted products in the rack, this worksheet can be ignored.
An operator serviceable, slide mounted product is defined as any product which
can be extended from the rack for servicing without requiring the use of any tool.
A product requiring the use of a tool to facilitate servicing or extending the
product is the definition of trained service personnel serviceable only. When a
trained service personnel serviceable only product is extended, the use of the
rack stabilizer assembly is required, but counterweight ballast is not. See Figure
11.
