where 

U  (mounting height) is multiple of the height unit 1U = 44.45 mm = 1¾” 

HP (mounting width) is a multiple of the horizontal pitch (HP) 

maximum of 84 HP 

1 HP = 5.08 mm 

Total width of the modular chassis = 482.6 mm = 19”.  

 

 
 

DISPOSAL 
 
Meaning of the "WEEE" logo found in labels 

The following symbol is applied in accordance with the EC WEEE (Waste Electrical and 
Electronic Equipment) Directive. 
This symbol (

valid only in countries of the European Community

) indicates that the 

product it applies to must NOT be disposed of together with ordinary domestic or industrial 
waste but must be sent to a differentiated waste collection system. 
The end user is therefore invited to contact the supplier of the device, whether the Parent 
Company or a retailer, to initiate the collection and disposal process after checking the 
contractual terms and conditions of sale.
