Installation 

Before installing the equipment, it is necessary to take the 
following precautions: 

1.) 

If the equipment is mounted in an enclosed or multiple rack 

assembly, the environmental temperature around the equipment 
must be less than or equal to 50

0

C. 

2.) 

If the equipment is mounted in an enclosed or multiple rack 

assembly, adequate air flow must be maintained for proper and 
safe operation. 

3.) 

If the equipment is mounted in an enclosed or multiple rack 

system placement of the equipment must not overload or load 
unevenly the rack system. 

4.) 

If the equipment is mounted in an enclosed or multiple rack 

assembly, verify the equipment’s power requirements to prevent 
overloading of the building/s electrical circuits. 

5.) 

 

If the equipment is mounted in an enclosed or multiple rack 

assembly verify that the equipment has a reliable and 
uncompromised earthing path.

 

6.) 

 

If  the intra-building wiring (cabling) is involved with 

this product, then it is recommended to have shielded cable and 
the shield is grounded at both ends.

well as connection of the various Ethernet media types. 

 

3.1 

Locating Magnum 4K220 Switches 

 

The location of a Magnum 4K-Series Switch is dependent on the physical 

layout of the network.  Typically the Switch is placed in a central wiring location where 

groups of network devices need to be connected in order to communicate with each 

other. These Switches are typically rack mounted in a wiring closet (see Section 3.3.2 

below), but they have rubber feet and can also be installed on a shelf or table top.  

Locate an AC receptacle that is within six feet (2 meters) of the intended 

Magnum 4K-Series site.  The rugged metal case of the Magnum 4K-Series will 

normally protect it from accidental damage in a lab or workplace setting.  Maintain an 

open view of the front to visually monitor the status LEDs.  Keep an open area around 

the unit so that cooling can occur from the small fan on the left side, while the unit is in 

operation. See figure below.
