The ETSI (European Telephone Standard) brackets are similar to the 19” 

brackets but use 
metric dimensions.   

The 

optional 23” 
brackets and the 
ETSI brackets 
come as a pair in a 
package along with 
the necessary 
screws for 
attaching the 
brackets to the 
sides of the 
Magnum Hub unit.  

The following instructions need to be follow up before installations- 

A) Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the 

operating ambient temperature of the rack environment may be greater than room 

ambient. Therefore, consideration should be given to installing the equipment in an 

environment compatible with the maximum ambient temperature (Tma) specified by the 

manufacturer.  

B) Reduced Air Flow - Installation of the equipment in a rack should be such that the 

amount of air flow required for safe operation of the equipment is not compromised.  

C) Mechanical Loading - Mounting of the equipment in the rack should be such that a 

hazardous condition is not achieved due to uneven mechanical loading.  

D) Circuit Overloading - Consideration should be given to the connection of the 

equipment to the supply circuit and the effect that overloading of the circuits might have 

on overcurrent protection and supply wiring. Appropriate consideration of equipment 

nameplate ratings should be used when addressing this concern.  

E) Reliable Earthing - Reliable earthing of rack-mounted equipment should be 

maintained. Particular attention should be given to supply connections other than direct 

connections to the branch circuit (e.g. use of power strips)."
