will not work.).

• A 5U space in the lower 20U of the rack. If planning to install above the 20U mark, a customer-

provided mechanical lift must be made available.

CAUTION: If installed in a closed-or multi-unit rack assembly, the operating ambient temperature 

of the rack environment may be greater than room ambient temperature. Therefore, install the 

equipment in an environment compatible with the maximum ambient temperature (Tma) 

specified by the manufacturer. For more information, see the Technical Specifications section in
