Issue: 
The AR8008BLK and AR8016ABLK are designed to install into the mounting rails of NetShelter SX 750mm wide cabinets. 

Product Line: 
NetShelter Cable Management

Environment: 
AR8008BLK and AR8016ABLK; all ranges and serial numbers. 

Cause: 
Customers need to move cables horizontally from front to rear in a 600mm wide NetShelter cabinet. 

Resolution:   
Yes, the AR8008BLK and AR8016ABLK can be installed in the narrower 600mm wide NetShelter cabinets when paired with a cable manager like AR8603A. 
The AR8603A has two large brush-stripped sections that allow cables to feed through. Each of these areas has slots to support up to two of the cable side channels. (4 cable side channels total) 
When the AR8603A are installed in the same U-space in the front and rear of the cabinet cable side channels can run between them. 
Some customers installing the AR8603A in the front of the cabinet may notice that the cable manager will interfere with the door closing when the rails are in their forward most position. This issue can be overcome by installing the cable manager to the rear of the front rails so the cable fingers are facing inward.
