Issue: 
We need to know if the tabs on the horizontal cable troughs will mount to the rails when vertical cable managers AR7580A, AR7585 or AR7588 are also installed. 

Product Line:
NetShelter SX Wide cabinets, vertical cable management and horizontal troughs. 

Environment: 
All 750mm wide NetShelter SX cabinets: AR7580A, AR7585, AR7588, AR8008BLK, AR8016ABLK; all serial numbers. 

Cause: 
A customer wants to use both vertical finger-style vertical cable managers and horizontal cable troughs on the mounting rails of a 750mm wide NetShelter SX cabinet. 

Resolution: 

Yes, when using vertical cable managers such as AR7580A, AR7585 and AR7588 you can still install the cable troughs which run front to rear: AR8008BLK or AR8016ABLK. 

Additionally, you may also use the roof brush strips AR7714 (5 per pack) to close off the holes in the cable managers and prevent hot air recirculation. 
The finger-style cable managers are a 2-piece item, and both pieces are required to fully populate one vertical mounting rail in the cabinet. 
One set of AR7580A requires 6 roof brush strips. 
One set of AR7585 requires 6 roof brush strips. 
One set of AR7588 requires 6 roof brush strips. Note: the vertical mounting rails for 48U cabinets have 7 thru-holes but the AR7588 only has 6. The center thru-hole in the mounting rails is covered by the AR7588.
