Explain and Identify PowerMax 2000 and 8000 Cabling POWERMAX-INSTALL Practice Questions (Page 1)

Questions 1–5

   You are reviewing a fabric diagram for a PowerMax 8000. It shows that engine A's director 1 connects to I/O bay 1 and I/O bay 2, but engine B's director 1 connects only to I/O bay 1. What is the most likely reason for this asymmetric cabling?

   • AEngine B's director 1 has a lower workload and does not need redundancy.
   • BThe system is configured with a single I/O bay for some directors to save on cabling costs.
   • CIt is a mistake in the diagram that must be corrected.
   • DThere may be a second link from engine B's director 1 to I/O bay 2 that is not shown, or the configuration intentionally uses a different redundancy scheme.

   A technician is performing a service procedure that requires replacing a power cable in a PowerMax 8000. The system is running in a redundant configuration. What must the technician do before disconnecting the old power cable?

   • AVerify that the other power supply is operational and carrying the load.
   • BRemove the power supply from the enclosure first.
   • CPower down the enclosure to avoid any electrical risk.
   • DDisconnect the cable quickly to minimize downtime.

   During a PowerMax 8000 installation, you notice that the power cables from the two power supplies in an engine enclosure are plugged into the same PDU. What is the potential risk of this configuration?

   • AIt creates a single point of failure if the PDU fails.
   • BIt violates the cable length specification for power cables.
   • CIt causes electromagnetic interference with data cables.
   • DIt prevents the power supplies from load-balancing.

   You are planning the physical installation of a PowerMax 2000. The fabric diagram indicates that each engine enclosure must connect to both I/O bays. What is the minimum number of cables required per engine to achieve this, assuming each engine has two directors and each director needs one link to each I/O bay?

   • AEight cables per engine, two from each director to each I/O bay.
   • BOne cable per engine, using a fan-out to both I/O bays.
   • CTwo cables per engine, one to each I/O bay.
   • DFour cables per engine, one from each director to each I/O bay.

   During a PowerMax 8000 installation, you are connecting power cables to the engine enclosures. What is the correct procedure for securing the power cables to the enclosure?

   • ALeave the cables loose so they can be easily disconnected for maintenance.
   • BPlug the cables in and ensure they are fully seated, then use the retention clips or latches provided.
   • CUse cable ties to secure the cables to the rack rails.
   • DWrap the cables around the enclosure handles to prevent strain.
