Table 41 Third-party rack requirements (continued)
Description
The customer rack should have redundant power zones, one on each side of the rack with
separate PDU power strips. Each redundant power zone should have capacity for the
maximum power load. NOTE: Dell EMC is not responsible for any failures, issues, or
outages resulting from failure of the customer provided PDUs.
Cables for the product must be routed in such a way that it mimics the standard ECS
Appliance offering coming from the factory. This includes dressing cables to the sides to
prevent drooping and interfering with service of field replaceable units (FRUs).
Optical cables should be dressed to maintain a 1.5 inches bend radius.
Cables for third-party components in the rack cannot cross or interfere with ECS logic
components in such a way that they block front to back air flow or individual FRU service
activity.
All DAEs should be installed in sequential order from bottom to top to prevent a tipping
risk.
WARNING
Opening more than one DAE at a time creates a tip hazard. ECS racks provide an
integrated solution to prevent more than one DAE from being open at a time.
Customer racks will not be able to support this feature.
Customer rack must be capable of supporting the weight of ECS equipment.
