Rack rails are leveraged from Dell PowerEdge HS5620:
- To support serviceability from only the front of the system (Cold Aisle Serviceability) for R670 and R770 only where the cold-aisle storage modules are offered, rack rails with blind mate to rear AC power connections shall be part of the R670 and R770 offering.
- "Blind mate" means:
- Shall remove and install the rack without entering the hot aisle behind the system, in example locating the system on the rails and pushing into the rack until it is seated properly.
- Only AC power connection shall be provisioned as blind mate. No other rear cables are plugged in when the system uses these rails.
- The new Front Node (See Storage section) has all the necessary IO for cold aisle serviceability.
